Definitions
- the disclosed device, system, and method relate to implants and, more particularly to implants for installation in an appendage for treating a variety of skeletal maladies including hammer toe.
- Hammer toe is a deformity of the toe that affects the alignment of the bones adjacent to the proximal interphalangeal (PIP) joint.
- Hammer toe can cause pain and can lead to difficulty in walking or wearing shoes.
- a hammer toe can often result in an open sore or wound on the foot.
- surgery may be required to correct the deformity by fusing one or both of the PIP and distal interphalangeal (DIP) joints.
- the most common corrective surgery includes the placement of a pin or rod in the distal, middle, and proximal phalanxes of the foot to fuse the PIP and DIP joints.
- the pin or rod is cut at the tip of the toe, externally of the body.
- a plastic or polymeric ball is placed over the exposed end of the rod, which remains in the foot of the patient until the PIP and/or DIP joints are fused in approximately 6 to 12 weeks.
- This conventional treatment has several drawbacks such as preventing the patient from wearing closed toe shoes while the rod or pin is in place, and the plastic or polymeric ball may snag a bed sheet or other object due to it extending from the tip of the toe resulting in substantial pain for the patient.
- Another conventional implant includes a pair of threaded members that are disposed within adjacent bones of a patient's foot. The implants are then coupled to one another through male-female connection mechanism, which is difficult to install in situ and has a tendency to separate.
- Yet another conventional implant has a body including an oval head and a pair of feet, which are initially compressed.
- the implant is formed from nitinol and is refrigerated until it is ready to be installed.
- the head and feet of the implant expand due to the rising temperature of the implant to provide an outward force on the surrounding bone when installed.
- the temperature sensitive material may result in the implant deploying or expanding prior to being installed, which requires a new implant to be used.
- an improved intramedullary implant for treating hammer toe and other maladies of the skeletal system is desirable that provides active compression across a joint and maintains compression thereafter so as to greatly increase the fusion rate.
- the implant should be insertable with minimal disruption to the DIP joint while optimizing compression and fixation at the PIP joint.
- Such an improved implant could find efficacy in Hammertoe surgery.
- An intramedullary implant system includes a body from each opposite end of which project a pair of beams arranged about a longitudinal axis of the body.
- the beams are each fixed to the body and each has a coupling latch with a bore so that the coupling latch of each of the beams of a pair may be releasably coupled to the other beam of the pair of beams by a removable coupling rod.
- a flexible tail projects from one end of the removable coupling rod projects outwardly.
- Each of the pair of beams is movable between (i) a coupled and biased position wherein the coupling rod is located in each bore of each latch so that the implant may be inserted into a respective bone with at least a portion of the flexible tail protruding from the implant, and (ii) an uncoupled position for internally gripping the respective bone.
- the beams of each pair in the uncoupled position diverge away from the longitudinal axis of the body wherein an outer surface of each beam is adapted to form a compressive engagement with the respective bone when disposed in the uncoupled position.
- a body has an end from which project a pair of beams arranged about a longitudinal axis of the body.
- the beams are each fixed to the body with the end of one of the beams being releasably coupled to the other beam of the pair by a removable coupling rod.
- a flexible tail projects from one end of the coupling rod.
- the beams are each deflectable between (i) a coupled and biased position for insertion of the beams into a respective bone and with at least a portion of the flexible tail positioned within a bone, and (ii) an uncoupled position for gripping the respective bone, the pair of beams in the uncoupled position being arranged so as to form a compressive engagement with the respective bone.
- a first k-wire is provided from one end of which extends a flexible tail.
- a body is provided from opposite ends of which project at least one pair of beams arranged about a longitudinal axis of the body.
- the beams are each fixed to the body and each have a coupling latch with a bore so that the coupling latch of each of the beams of a pair may be releasably coupled to the other beam of the pair of beams by the k-wire such that each of the pair of beams is movable between (i) a coupled and biased position wherein the k-wire is located in each bore of each latch so that the implant may be inserted into a respective bone and (ii) an uncoupled position wherein the k-wire is removed from each bore of each latch so that the beams of each pair diverge away from the longitudinal axis of the body wherein an outer surface of each beam is adapted to form a compressive engagement with the respective bone when disposed in the uncoupled position.
- a method for implanting a device within a bone includes opening and debriding a target bone system.
- a canal is formed through the target bone system, and a k-wire is provided that has a flexible tail extending from one end.
- An implant is also provided that includes a body from opposite ends of which project at least one pair of beams arranged about a longitudinal axis of the body wherein the body defines a passageway along the longitudinal axis.
- the beams are each fixed to the body and each has a coupling latch with a bore.
- the latch of each beam is releasably coupled to one another by inserting the k-wire into the latch bores thereby biasing the beams.
- the implant and k-wire are inserted into the canal along with the flexible tail, often protruding from the patient's body.
- the flexible tail By pulling upon the flexible tail so as to decouple and remove the k-wire from the latches, the beams are thereby decoupled and released from their biased state so that a portion of each beam engages the surface of the surrounding bone that defines the canal.

- Implant 2 may be manufactured from conventional implant metal, such as stainless steel or titanium.
- the implants are manufactured out of shape memory materials (SMA) or alloys such as nickel titanium to enhance fixation.
- SMA shape memory materials
- Nitinol sold by Memry Corporation of Menlo Park, Calif.
- the implants are preferably made of nitinol, a biocompatible, shape memory metal alloy of titanium and nickel.
- the metal's properties at the higher temperature (austenite phase) are similar to those of titanium.
- the temperature at which the implants will undergo the shape transformation can be controlled by the manufacturing process and the selection of the appropriate alloy composition.
- Nitinol has a very low corrosion rate and has been used in a variety of medical implants, e.g., orthodontic appliances, stents, suture anchors, etc. Implant studies in animals have shown minimal elevations of nickel in the tissues in contact with the metal; the levels of titanium are comparable to the lowest levels found in tissues near titanium hip prostheses.
- the SMA is selected to have a temperature transformation range such that the implant undergoes a transition from austenite to stress-induced martensite under the influence of deformation forces.
- the distal and proximal beams of implant 2 are deflected inwardly, toward one another and then released, they are already at a temperature such that they automatically attempt to reform to their original shape.
- implant 2 is prepared for use in corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot, as follows.
- Distal pair of beams 6 are loaded so that they each deflect inwardly, toward one another until latch-plate 38 is located adjacent to latch-plate 34 with bore 36 a and bore 36 b overlapping one another.
- proximal pair of beams 8 are also loaded so that they each deflect inwardly, toward one another until latch-plate 58 is located adjacent to latch-plate 54 with bore 56 a and bore 56 b overlapping one another.
- a coupling rod such as k-wire 60
- k-wire 60 is inserted through bores 56 a, 56 b, through-bore 18 , and bores 36 a bore 36 b, thereby coupling distal pair of beams 6 and proximal pair of beams 8 in their respective optimally biased state.
- k-wire 60 includes a proximal portion 63 that has a smaller diameter than the distal portion of the k-wire thereby defining a shoulder 67 at the transition 69 between diameters. Shoulder 67 is often sized so as to engage the outer surface of latch-plate 54 and thereby prevent k-wire 60 from further travel into implant 2 beyond transition 69 .
- a k-wire 61 comprises a flexible tail 62 that is terminated by a second k-wire 64 .
- Flexible tail 62 may be fashioned from woven, non-woven, knitted, braided or crocheted materials, any of which can included but not be limited to standard surgical sutures, polymer or fiberous cords, metal wire or tape, or the like, and may be formed from a single multiple strands of metals, polymers, or other bio compatible materials. Often, flexible tail 62 comprises a metal braid or cable.
- K-wire 61 may have a circular, oval or flattened cross-sectional profile similar to that of K-wire 60 b ( FIGS. 20-23 ).
- Implant 2 is used in systems and methods for corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot or elsewhere in bones of the human or animal body, as follows.
- the PIP joint is first opened and debrided and an initial k-wire 75 ( FIG. 5 ) is inserted through the axis of the middle phalanx A and out the distal end of the toe.
- Initial k-wire 75 is then removed distally from the distal tip of the toe ( FIGS. 5A and 6 ).
- a canal D is defined through distal and proximal portions of the PIP joint.
- Canal D extends for a distance into middle phalanx A along the path defined previously by k-wire 75 such that a counter-bore shoulder 71 is defined at the transition between the diameters of canal D and the passageway formed by the prior insertion of k-wire 75 .
- Shoulder 71 is often sized so as to engage the outer surface of a latch-plate 54 or 34 and thereby prevent implant 2 from further distal travel into middle phalanx A.
- an implant 2 that has been coupled to a k-wire 60 or 61 is inserted through broached canal D ( FIGS. 7 and 7B ) such that k-wire 60 travels through middle phalanx A and distal phalanx B with distal end portion 63 projecting outwardly from the end of distal phalanx B.
- flexible tail 62 travels through middle phalanx A and distal phalanx B with distal end portion 63 projecting outwardly from the end of distal phalanx B.
- Flexible tail 62 may often be employed to ease implantation.
- a cord 62 provides the flexibility that is often needed by the surgeon to position the implant within the patient's bone, while maintaining tensile strength for removing k-wire 61 from the implant during deployment.
- flexible tail 62 and k-wire are left protruding from the patient's foot F by the surgeon so as to allow the patient to slip on a shoe G or other foot wear ( FIG. 9E ).
- a rigid k-wire was left protruding from the patient's toe by the surgeon, when the surgery was completed. This arrangement prevented the patient from wearing shoes which often precluded the patient from returning to work based upon work place safety regulations.
- implant 2 travels down the longitudinal axis of middle phalanx A until the constrained distal beams 6 are adjacent shoulder 71 within broached canal D ( FIG. 7 ). Once in position, end portions of distal pair of beams 6 are located adjacent to shoulder 71 within middle phalanx A and proximal pair of beams 8 project outwardly from the open end of canal D at the proximal end of middle phalanx A.
- the joint is re-aligned and closed by moving the distal and middle phalanxes so that proximal pair of beams 8 is caused to enter the open end of canal D in proximal phalanx C ( FIG. 8 ). In this position, proximal pair of beams 8 are located within canal D in proximal phalanx C and the joint is closed around implant 2 .
- k-wire 60 is moved distally ( FIG. 9 ) so as to disengage from latch-plates 54 and 58 of proximal beams 8 thereby decoupling and releasing beams 44 and 46 from their optimally biased state.
- k-wire 64 is moved distally ( FIG. 8B and 9C )) thereby pulling flexible tail 62 and k-wire 61 so as to disengage from latch-plates 54 and 58 of proximal beams 8 thereby decoupling and releasing beams 44 and 46 from their optimally biased state.
- superior beam 44 and inferior beam 46 spring outwardly, away from one another, until their respective barbs 50 a and 50 b engage the surface of the surrounding bone that defines broached canal D. Since superior beam 44 and inferior beam 46 are still biased, i.e., continue to store some elastic energy, but are geometrically shortened by an amount 6 . Barbs 50 a and 50 b compressively engage the surface of the surrounding bone so as to “bite” into the bone, thus enhancing the retention of implant 2 . It should be noted that the respective shortening of the moment arm of proximal pair of beams 8 applies an active compressive force to articulating surfaces of the PIP joint.
- K-wire 60 continues to be decoupled and withdrawn from implant 2 , through through-bore 18 of cannulated body 4 until distal end 70 slips past through-bores 36 a, 36 b in latch-plates 34 and 38 of distal pair of beams 6 so as to entirely decouple k-wire 60 from implant 2 ( FIG. 9 ).
- superior beam 24 and inferior beam 26 spring outwardly, away from one another and away from their optimally biased state into a partially biased state in which distal pair of beams 6 engage the surface of the bone that defines broached canal D.
- cantilevered distal pair of beams 6 move into their second partially biased state, they will also shorten.
- This geometric effect applies an active compressive force to the articulating surfaces of the PIP joint while proximal pair of beams 8 maintain cortical fixation on either side of the joint.
- barbs 30 a and barbs 30 b are caused to bite into the bone that defines broached canal D by the outward force of superior beam 24 and inferior beam 26 moving into their partially biased state. The biting of barbs 30 a and 30 b into the bone greatly enhances the compressive load exerted by proximal pair of beams 8 .
- an implant 2 that has been coupled to a k-wire 60 is inserted through broached canal D ( FIG. 6A ).
- implant 2 travels along the longitudinal axis of middle phalanx A until the constrained proximal beams 8 are adjacent the end of broached canal D within proximal phalanx C ( FIG. 7A ).
- k-wire 60 is moved distally ( FIG. 8A ) so as to disengage distal portion 63 from latch-plates 34 and 38 of proximal beams 8 thereby decoupling and releasing beams 24 and 26 from their optimally biased state.
- superior beam 24 and inferior beam 26 spring outwardly, away from one another, until their respective barbs 30 a and 30 b engage the surface of the surrounding bone that defines broached canal D. Since superior beam 24 and inferior beam 26 are still biased, i.e., continue to store some elastic energy, but are geometrically shortened by an amount ⁇ , barbs 30 a and 30 b compressively engage the surface of the surrounding bone so as to “bite” into the bone, thus enhancing the retention of implant 2 . It should be noted that the respective shortening of the moment arm of proximal pair of beams 8 applies an active compressive force to articulating surfaces of the PIP joint while distal pair of beams 6 maintain cortical fixation via barbs 30 a and 30 b.
- proximal pair of beams 8 With proximal pair of beams 8 fully seated within the proximal phalanx C, the joint is compressed axially so as to fully seat proximal pair of beams 8 within broached canal D ( FIG. 8A ).
- K-wire 60 continues to be decoupled and withdrawn from implant 2 , through through-bore 18 of cannulated body 4 until proximal end 70 slips past through-bores 56 a, 56 b in latch-plates 54 and 58 of distal pair of beams 6 so as to entirely decouple k-wire 60 from distal pair of beams 6 ( FIG. 9A ).
- distal pair of beams 6 spring outwardly, away from one another and away from their optimally biased state into a partially biased state in which distal pair of beams 6 engage surface of the bone that defines broached canal D.
- cantilevered distal pair of beams 6 move into their second partially biased state, they will also shorten their length. This geometric effect applies an active compressive force to the articulating surfaces of the PIP joint while distal pair of beams 6 maintain cortical fixation.
- barbs 50 a located on an outer surface 51 of superior beam 44 and barbs 50 b located on outer surface 52 of inferior beam 46 are caused to bite into the bone that defines broached canal D by the outward force of superior beam 44 and inferior beam 46 moving into their partially biased state.
- the biting of barbs 30 a, 30 b, 50 a and 50 b into the internal bone surfaces at both sides of the joint, coupled with the geometric shortening of both proximal beams 8 and distal beams 6 greatly enhances the compressive load exerted across the PIP joint.

Abstract
An intramedullary implant system, and method for placement within a bone system are provided by the invention. The implant includes a body with at least one pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body and each have an end. The end of one of the beams of a pair is releasably coupled to the other beam of the pair by a k-wire from one end of which extends a flexible tail. The beams are each deflectable between (i) a coupled and biased position for insertion of the beams into a respective bone, and (ii) an uncoupled position for gripping bone. The beams of each pair in the uncoupled position being arranged so as to compressively engage the bone.
Description
- This application is a continuation-in-part application of co-pending U.S. application Ser. No. 14/179,172, filed on Feb. 12, 2014, the entirety of which is incorporated by reference herein.
- The disclosed device, system, and method relate to implants and, more particularly to implants for installation in an appendage for treating a variety of skeletal maladies including hammer toe.
- Hammer toe is a deformity of the toe that affects the alignment of the bones adjacent to the proximal interphalangeal (PIP) joint. Hammer toe can cause pain and can lead to difficulty in walking or wearing shoes. A hammer toe can often result in an open sore or wound on the foot. In some instances, surgery may be required to correct the deformity by fusing one or both of the PIP and distal interphalangeal (DIP) joints.
- The most common corrective surgery includes the placement of a pin or rod in the distal, middle, and proximal phalanxes of the foot to fuse the PIP and DIP joints. The pin or rod is cut at the tip of the toe, externally of the body. A plastic or polymeric ball is placed over the exposed end of the rod, which remains in the foot of the patient until the PIP and/or DIP joints are fused in approximately 6 to 12 weeks. This conventional treatment has several drawbacks such as preventing the patient from wearing closed toe shoes while the rod or pin is in place, and the plastic or polymeric ball may snag a bed sheet or other object due to it extending from the tip of the toe resulting in substantial pain for the patient.
- Another conventional implant includes a pair of threaded members that are disposed within adjacent bones of a patient's foot. The implants are then coupled to one another through male-female connection mechanism, which is difficult to install in situ and has a tendency to separate.
- Yet another conventional implant has a body including an oval head and a pair of feet, which are initially compressed. The implant is formed from nitinol and is refrigerated until it is ready to be installed. The head and feet of the implant expand due to the rising temperature of the implant to provide an outward force on the surrounding bone when installed. However, the temperature sensitive material may result in the implant deploying or expanding prior to being installed, which requires a new implant to be used.
- Accordingly, an improved intramedullary implant for treating hammer toe and other maladies of the skeletal system is desirable that provides active compression across a joint and maintains compression thereafter so as to greatly increase the fusion rate. The implant should be insertable with minimal disruption to the DIP joint while optimizing compression and fixation at the PIP joint. Such an improved implant could find efficacy in Hammertoe surgery.
- An intramedullary implant system is provided that includes a body from each opposite end of which project a pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body and each has a coupling latch with a bore so that the coupling latch of each of the beams of a pair may be releasably coupled to the other beam of the pair of beams by a removable coupling rod. A flexible tail projects from one end of the removable coupling rod projects outwardly. Each of the pair of beams is movable between (i) a coupled and biased position wherein the coupling rod is located in each bore of each latch so that the implant may be inserted into a respective bone with at least a portion of the flexible tail protruding from the implant, and (ii) an uncoupled position for internally gripping the respective bone. The beams of each pair in the uncoupled position diverge away from the longitudinal axis of the body wherein an outer surface of each beam is adapted to form a compressive engagement with the respective bone when disposed in the uncoupled position.
- In another embodiment of a intramedullary implant system, a body has an end from which project a pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body with the end of one of the beams being releasably coupled to the other beam of the pair by a removable coupling rod. A flexible tail projects from one end of the coupling rod. The beams are each deflectable between (i) a coupled and biased position for insertion of the beams into a respective bone and with at least a portion of the flexible tail positioned within a bone, and (ii) an uncoupled position for gripping the respective bone, the pair of beams in the uncoupled position being arranged so as to form a compressive engagement with the respective bone.
- In a further embodiment of an intramedullary implant system a first k-wire is provided from one end of which extends a flexible tail. A body is provided from opposite ends of which project at least one pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body and each have a coupling latch with a bore so that the coupling latch of each of the beams of a pair may be releasably coupled to the other beam of the pair of beams by the k-wire such that each of the pair of beams is movable between (i) a coupled and biased position wherein the k-wire is located in each bore of each latch so that the implant may be inserted into a respective bone and (ii) an uncoupled position wherein the k-wire is removed from each bore of each latch so that the beams of each pair diverge away from the longitudinal axis of the body wherein an outer surface of each beam is adapted to form a compressive engagement with the respective bone when disposed in the uncoupled position.
- A method for implanting a device within a bone is provided that includes opening and debriding a target bone system. A canal is formed through the target bone system, and a k-wire is provided that has a flexible tail extending from one end. An implant is also provided that includes a body from opposite ends of which project at least one pair of beams arranged about a longitudinal axis of the body wherein the body defines a passageway along the longitudinal axis. The beams are each fixed to the body and each has a coupling latch with a bore. The latch of each beam is releasably coupled to one another by inserting the k-wire into the latch bores thereby biasing the beams. The implant and k-wire are inserted into the canal along with the flexible tail, often protruding from the patient's body. By pulling upon the flexible tail so as to decouple and remove the k-wire from the latches, the beams are thereby decoupled and released from their biased state so that a portion of each beam engages the surface of the surrounding bone that defines the canal.

In the description, relative terms such as “horizontal,” “vertical,” “up,” “down,” “top,” and “bottom” as well as derivatives thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion. These relative terms are for convenience of description and normally are not intended to require a particular orientation. Terms including “inwardly” versus “outwardly,” “longitudinal” versus “lateral,” and the like are to be interpreted relative to one another or relative to an axis of elongation, or an axis or center of rotation, as appropriate. Terms concerning attachments and the like, such as “coupled” and “coupling” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly, temporarily or permanently, through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise. The term “operatively coupled” is such an attachment or connection that allows the pertinent structures to operate as intended by virtue of that relationship.
- Referring to
FIGS. 1-4 , animplant 2 is provided that includes a cannulatedbody 4, a distal pair ofcantilevered beams 6, and a proximal pair ofcantilevered beams 8. More particularly, cannulatedbody 4 often comprises an elongate bar having adistal end 14 and aproximal end 15. A through-bore 18 is often defined centrally through the bar alonglongitudinal axis 17 so as to define openings atdistal end 14 andproximal end 15. - Distal pair of
beams 6 comprise asuperior beam 24 and aninferior beam 26 arranged in spaced confronting relation to one another atdistal end 14 of cannulatedbody 4. In many of the embodiments of the invention, pairs of beams will be arranged symmetrically aboutlongitudinal axis 17 ofbody 4, often so as to be bisected by the axis.Superior beam 24 is fixed todistal end 14 of cannulatedbody 4, and in some embodiments, is formed integral withcannulated body 4. One ormore barbs 30 a are located on anouter surface 31 ofsuperior beam 24, often oriented transversely acrossouter surface 31. A latch-plate 34 extends inwardly, towardinferior beam 26, from a free end ofsuperior beam 24. A bore 36 a is defined through latch-plate 34.Inferior beam 26 is fixed todistal end 14 of cannulatedbody 4, and in some embodiments, is formed integral withcannulated body 4. One ormore barbs 30 b are located on a distalouter surface 32 ofinferior beam 26, often oriented transversely acrossouter surface 32. A latch-plate 38 extends inwardly, towardsuperior beam 24 and latch-plate 34, from a free end ofinferior beam 26. A bore 36 b is defined through latch-plate 38. - Distal pair of
beams 6 are cantilevered to cannulatedbody 4 atdistal end 14, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When distal pair ofbeams 6 are loaded during normal use, they each deflect inwardly, toward one another. Advantageously,superior beam 24 is greater in length thaninferior beam 26 so that, when deflected to a optimally biased state, i.e., the beams are deflected so that a desirable amount of elastic energy is stored, with latch-plate 34 is located in overlapping adjacent relation to latch-plate 38 withbore 36 a and bore 36 b overlapping and communicating relation to one another (FIGS. 3-4 ). As a result, while distal pair ofbeams 6 are loadedbores bore 18 atdistal end 14 of cannulatedbody 4. - Proximal pair of
beams 8 comprise asuperior beam 44 and aninferior beam 46 arranged in spaced confronting relation to one another atproximal end 15 of cannulatedbody 4.Superior beam 44 is fixed toproximal end 15 of cannulatedbody 4, and in some embodiments, is formed integral withcannulated body 4. One ormore barbs 50 a are located on anouter surface 51 ofsuperior beam 44, often oriented transversely acrossouter surface 51. A latch-plate 54 extends inwardly, towardinferior beam 46, from a free end ofsuperior beam 44. A bore 56 b is defined through latch-plate 54.Inferior beam 46 is fixed toproximal end 15 of cannulatedbody 4, and in some embodiments, is formed integral withcannulated body 4. One ormore barbs 50 b are located on a distalouter surface 52 ofinferior beam 46, often oriented transversely acrossouter surface 52. A latch-plate 58 extends inwardly, towardsuperior beam 44 and latch-plate 54, from a free end ofinferior beam 46. A bore 56 a is defined through latch-plate 58. - As with distal pair of
beams 6, proximal pair ofbeams 8 are also cantilevered to cannulatedbody 4, but atproximal end 15, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When proximal pair ofbeams 8 are loaded during normal use, they each deflect inwardly, toward one another. Advantageously,superior beam 44 is greater in length thaninferior beam 46 so that, when deflected to a optimally biased state, latch-plate 58 is located adjacent to latch-plate 54 withbore 56 a and bore 56 b overlapping one another. As a result, bores 56 a and 56 b often will be arranged in substantially coaxial relation to the open end of through-bore 18 atproximal end 15 of cannulatedbody 4. - When cantilevered distal pair of
beams 6 and proximal pair ofbeams 8 move into their respective second partially biased state, they undergo a so-called “large deflection” in accordance with classical beam theory. In other words, the moment arm of each ofsuperior beam inferior beam FIG. 4 , it will be understood by those skilled in the art that when distal pair ofbeams 6 and proximal pair ofbeams 8 are arranged in their optimally biased state, the distance β measured between their outer most barbs is at a maximum, but when cantilevered distal pair ofbeams 6 and proximal pair ofbeams 8 are allowed to move into their respective second partially biased state, the distance θ measured between the outer most barbs is at a minimum. Thus, there is a differential in the length of the beams, δ, between their optimally biased state and their second partially biased state. This difference δ represents an available amount of compressive engagement or “bite” of the barbs into the bone that defines broached canal D. -
Implant 2 may be manufactured from conventional implant metal, such as stainless steel or titanium. In several preferred embodiments, however, the implants are manufactured out of shape memory materials (SMA) or alloys such as nickel titanium to enhance fixation. One example of such an alloy is Nitinol sold by Memry Corporation of Menlo Park, Calif. The implants are preferably made of nitinol, a biocompatible, shape memory metal alloy of titanium and nickel. The metal's properties at the higher temperature (austenite phase) are similar to those of titanium. The temperature at which the implants will undergo the shape transformation can be controlled by the manufacturing process and the selection of the appropriate alloy composition. Nitinol has a very low corrosion rate and has been used in a variety of medical implants, e.g., orthodontic appliances, stents, suture anchors, etc. Implant studies in animals have shown minimal elevations of nickel in the tissues in contact with the metal; the levels of titanium are comparable to the lowest levels found in tissues near titanium hip prostheses. In most embodiments of the invention, the SMA is selected to have a temperature transformation range such that the implant undergoes a transition from austenite to stress-induced martensite under the influence of deformation forces. Thus, when the distal and proximal beams ofimplant 2 are deflected inwardly, toward one another and then released, they are already at a temperature such that they automatically attempt to reform to their original shape. - Referring to
FIGS. 5-9A ,implant 2 is prepared for use in corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot, as follows. Distal pair ofbeams 6 are loaded so that they each deflect inwardly, toward one another until latch-plate 38 is located adjacent to latch-plate 34 withbore 36 a and bore 36 b overlapping one another. Likewise, proximal pair ofbeams 8 are also loaded so that they each deflect inwardly, toward one another until latch-plate 58 is located adjacent to latch-plate 54 withbore 56 a and bore 56 b overlapping one another. Once in this arrangement, a coupling rod, such as k-wire 60, is inserted throughbores bore 18, and bores 36 abore 36 b, thereby coupling distal pair ofbeams 6 and proximal pair ofbeams 8 in their respective optimally biased state. In some embodiments, k-wire 60 includes aproximal portion 63 that has a smaller diameter than the distal portion of the k-wire thereby defining ashoulder 67 at thetransition 69 between diameters.Shoulder 67 is often sized so as to engage the outer surface of latch-plate 54 and thereby prevent k-wire 60 from further travel intoimplant 2 beyondtransition 69. In another embodiment shown inFIG. 9B , a k-wire 61 comprises aflexible tail 62 that is terminated by a second k-wire 64.Flexible tail 62 may be fashioned from woven, non-woven, knitted, braided or crocheted materials, any of which can included but not be limited to standard surgical sutures, polymer or fiberous cords, metal wire or tape, or the like, and may be formed from a single multiple strands of metals, polymers, or other bio compatible materials. Often,flexible tail 62 comprises a metal braid or cable. K-wire 61 may have a circular, oval or flattened cross-sectional profile similar to that of K-wire 60 b (FIGS. 20-23 ). -
Implant 2 is used in systems and methods for corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot or elsewhere in bones of the human or animal body, as follows. The PIP joint is first opened and debrided and an initial k-wire 75 (FIG. 5 ) is inserted through the axis of the middle phalanx A and out the distal end of the toe. Initial k-wire 75 is then removed distally from the distal tip of the toe (FIGS. 5A and 6 ). Using a broach or similar instrument (not shown) a canal D is defined through distal and proximal portions of the PIP joint. Canal D extends for a distance into middle phalanx A along the path defined previously by k-wire 75 such that acounter-bore shoulder 71 is defined at the transition between the diameters of canal D and the passageway formed by the prior insertion of k-wire 75.Shoulder 71 is often sized so as to engage the outer surface of a latch-plate implant 2 from further distal travel into middle phalanx A. - Once the surgical site has been prepared in the foregoing manner, an
implant 2 that has been coupled to a k-wire FIGS. 7 and 7B ) such that k-wire 60 travels through middle phalanx A and distal phalanx B withdistal end portion 63 projecting outwardly from the end of distal phalanx B. In the alternative,flexible tail 62 travels through middle phalanx A and distal phalanx B withdistal end portion 63 projecting outwardly from the end of distal phalanxB. Flexible tail 62 may often be employed to ease implantation. In one embodiment, acord 62 provides the flexibility that is often needed by the surgeon to position the implant within the patient's bone, while maintaining tensile strength for removing k-wire 61 from the implant during deployment. In one embodiment,flexible tail 62 and k-wire are left protruding from the patient's foot F by the surgeon so as to allow the patient to slip on a shoe G or other foot wear (FIG. 9E ). Traditionally, a rigid k-wire was left protruding from the patient's toe by the surgeon, when the surgery was completed. This arrangement prevented the patient from wearing shoes which often precluded the patient from returning to work based upon work place safety regulations. - With either arrangement,
implant 2 travels down the longitudinal axis of middle phalanx A until the constraineddistal beams 6 areadjacent shoulder 71 within broached canal D (FIG. 7 ). Once in position, end portions of distal pair ofbeams 6 are located adjacent toshoulder 71 within middle phalanx A and proximal pair ofbeams 8 project outwardly from the open end of canal D at the proximal end of middle phalanx A. Next, the joint is re-aligned and closed by moving the distal and middle phalanxes so that proximal pair ofbeams 8 is caused to enter the open end of canal D in proximal phalanx C (FIG. 8 ). In this position, proximal pair ofbeams 8 are located within canal D in proximal phalanx C and the joint is closed aroundimplant 2. - Once in the foregoing arrangement, k-
wire 60 is moved distally (FIG. 9 ) so as to disengage from latch-plates proximal beams 8 thereby decoupling and releasingbeams wire 64 is moved distally (FIG. 8B and 9C )) thereby pullingflexible tail 62 and k-wire 61 so as to disengage from latch-plates proximal beams 8 thereby decoupling and releasingbeams superior beam 44 andinferior beam 46 spring outwardly, away from one another, until theirrespective barbs superior beam 44 andinferior beam 46 are still biased, i.e., continue to store some elastic energy, but are geometrically shortened by anamount 6.Barbs implant 2. It should be noted that the respective shortening of the moment arm of proximal pair ofbeams 8 applies an active compressive force to articulating surfaces of the PIP joint. K-wire 60 continues to be decoupled and withdrawn fromimplant 2, through through-bore 18 of cannulatedbody 4 untildistal end 70 slips past through-bores plates beams 6 so as to entirely decouple k-wire 60 from implant 2 (FIG. 9 ). As a consequence,superior beam 24 andinferior beam 26 spring outwardly, away from one another and away from their optimally biased state into a partially biased state in which distal pair ofbeams 6 engage the surface of the bone that defines broached canal D. Here again, it will be understood by those skilled in the art that as cantilevered distal pair ofbeams 6 move into their second partially biased state, they will also shorten. This geometric effect applies an active compressive force to the articulating surfaces of the PIP joint while proximal pair ofbeams 8 maintain cortical fixation on either side of the joint. Advantageously,barbs 30 a andbarbs 30 b are caused to bite into the bone that defines broached canal D by the outward force ofsuperior beam 24 andinferior beam 26 moving into their partially biased state. The biting ofbarbs beams 8. - In an alternative embodiment illustrated in
FIGS. 6A-9A , once the surgical site has been prepared as described hereinabove, animplant 2 that has been coupled to a k-wire 60 is inserted through broached canal D (FIG. 6A ). In this way,implant 2 travels along the longitudinal axis of middle phalanx A until the constrainedproximal beams 8 are adjacent the end of broached canal D within proximal phalanx C (FIG. 7A ). Once in position, k-wire 60 is moved distally (FIG. 8A ) so as to disengagedistal portion 63 from latch-plates proximal beams 8 thereby decoupling and releasingbeams superior beam 24 andinferior beam 26 spring outwardly, away from one another, until theirrespective barbs superior beam 24 andinferior beam 26 are still biased, i.e., continue to store some elastic energy, but are geometrically shortened by an amount δ,barbs implant 2. It should be noted that the respective shortening of the moment arm of proximal pair ofbeams 8 applies an active compressive force to articulating surfaces of the PIP joint while distal pair ofbeams 6 maintain cortical fixation viabarbs - With proximal pair of
beams 8 fully seated within the proximal phalanx C, the joint is compressed axially so as to fully seat proximal pair ofbeams 8 within broached canal D (FIG. 8A ). K-wire 60 continues to be decoupled and withdrawn fromimplant 2, through through-bore 18 of cannulatedbody 4 untilproximal end 70 slips past through-bores plates beams 6 so as to entirely decouple k-wire 60 from distal pair of beams 6 (FIG. 9A ). As a consequence, distal pair ofbeams 6 spring outwardly, away from one another and away from their optimally biased state into a partially biased state in which distal pair ofbeams 6 engage surface of the bone that defines broached canal D. Here again, it will be understood by those skilled in the art that as cantilevered distal pair ofbeams 6 move into their second partially biased state, they will also shorten their length. This geometric effect applies an active compressive force to the articulating surfaces of the PIP joint while distal pair ofbeams 6 maintain cortical fixation. Advantageously,barbs 50 a located on anouter surface 51 ofsuperior beam 44 andbarbs 50 b located onouter surface 52 ofinferior beam 46 are caused to bite into the bone that defines broached canal D by the outward force ofsuperior beam 44 andinferior beam 46 moving into their partially biased state. The biting ofbarbs proximal beams 8 anddistal beams 6, greatly enhances the compressive load exerted across the PIP joint. - Numerous changes in the details of the embodiments disclosed herein will be apparent to, and may be made by, persons of ordinary skill in the art having reference to the foregoing description. For example, and referring to
FIGS. 10-12 ,implant 82 is provided that includes abody 84, a distal pair ofcantilevered beams 86, and a proximal pair of cantilevered beams 88. Unlike cannulatedbody 4 ofimplant 2,body 84 defines an elongate, channel or groove 90 having adistal end 94 and aproximal end 95. Distal pair ofbeams distal end 94 ofbody 84. Eachbeam distal end 94 and in some embodiments, is formed integral withbody 84. One ormore barbs 96 are located on an outer surface of eachdistal beam groove 90 extends through an inner portion ofbody 84. An open-endedgroove 100 a is defined as a channel through an inner distal portion ofdistal beam 86 b (FIG. 10 ) that is sized so as to slidingly receive a sharpened portion of a k-wire 60 a. Distal pair ofbeams body 84, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When distal pair ofbeams - Proximal pair of
beams proximal end 95 ofbody 84. One ormore barbs 96 are located on an outer surface of eachproximal beam groove 100 b is defined as a channel through an inner distal portion ofproximal beam 88 a (FIGS. 10 and 11 ) that is sized so as to slidingly receive a rounded portion of k-wire 60 b. As with distal pair ofbeams beams body 84 but atproximal end 95, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When proximal pair ofbeams -
Implant 82 is prepared for use in corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot in much the same way asimplant 2. More particularly, distal pair ofbeams groove 90 ofbody 84 and groove 100 a are arranged in substantially coaxial relation to one another. Likewise, proximal pair ofbeams groove 90 ofbody 84 and groove 100 b are arranged in substantially coaxial relation to one another. Once in this arrangement, k-wire 60 a is inserted throughgroove 100 a, open-endedgroove 90, and groove 100 b, thereby coupling distal pair ofbeams beams - As with
implant 2, removal and decoupling of k-wire 60 causes distal pair ofbeams beams barbs 96 are caused to bite compressively into the bone that defines the broached canal by the force of distal pair ofbeams beams barbs 96 into the bone greatly enhances the compressive load exerted byimplant 82. When distal pair ofbeams beams wire 60 is fully decoupled, the elongate channel or groove 90 having adistal end 94 and aproximal end 95 is again able to slidingly receive k-wire 60. The sharpenedportion 60 a of k-wire 60 is, e.g., driven proximally through the tip of the patient's toe and throughdistal end 94 andproximal end 95 ofgroove 90 ofimplant 82 to achieve temporary stabilization of outlying joints (e.g., the MTP joint). - Implants in accordance with the general principles of the invention may be take a variety of configurations. Referring to
FIGS. 13-17 , aproximal beam 86 a anddistal beam 88 b, may be arranged on their respective ends ofbody 84 with somewhat thinner or variable cross-sections so as to allow for adjustments in spring force to a predetermined level as may be needed for a particular therapy. Referring toFIGS. 18-19 , it will be understood thatimplant 2 may incorporate an inferior latch-plate corresponding beam FIGS. 20-23 ,implant 2 may have any peripheral shape. Often,implant 2 will have a circular or elliptical peripheral shape so as to be better suited for disposition through drilled canal D. It should be noted that with circular or elliptical embodiments ofimplant 2, bores 36 a, 36 b or 56 a, 56 b may be defined with one or more partially flattenedwalls 110 so as to allow for sufficient wall thickness in latch plate and for engagement with a correspondingly shaped k-wire 60 b. This arrangement allows the surgeon to rotationallyorient implant 2 relative to the bone surface that defines broached canal D. As shown inFIGS. 24 and 27 , animplant 112 may be formed so as to bend at or adjacent to the central portion ofbody 4 a. In these embodiments, distal pair ofbeams 6 or proximal pair ofbeams 8 may be arranged and oriented at an angle relative tobody 4 a. A similarly shaped k-wire also comprised of Nitinol to insert throughbend 60 c is coupled and decoupled during use ofimplant 112 in a manner previously disclosed herein. - Turning now to
FIGS. 28-29 , animplant 122 is provided that includes abody 124, a distalcantilevered beam 126, and a proximalcantilevered beam 128.Body 124 defines an throughbore 130 and has a distal end 134 and a proximal end 135.Proximal beam 126 projects longitudinally outwardly from distal end ofbody 124, while distal cantileveredbeam 128 projects longitudinally outwardly from the proximal end ofbody 124. One or more barbs 136 are located on an outer surface of each of distal end 134 and a proximal end 135. A latch-plate 140 extends inwardly from a free end of proximalcantilevered beam 126 and a second latch-plate 142 extends inwardly from a free end of distal cantileveredbeam 128. Abore 146 a is defined through latch-plate 140 and abore 146 b is defined through latch-plate 142.Cantilevered beams body 124, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When cantilevered beams 124, 126 are loaded during normal use, they each deflect inwardly. Advantageously, cantileveredbeams body 124. -
Implant 122 is prepared for use in corrective surgery at the distal B, middle A, and proximal C phalanxes of the foot in much the same way asimplant 2. More particularly, proximalcantilevered beam 126 and distalcantilevered beam 128 are loaded so that they each deflect inwardly, toward the longitudinal axis of throughbore 130 ofbody 124 so that bore 146 a of latch-plate 140 and bore 146 b of latch-plate 142 are arranged in substantially coaxial relation to one another. Once in this arrangement, k-wire 60 is inserted throughbore 130, bore 146 a, and bore 146 b, thereby coupling distal cantileveredbeam 126, and proximalcantilevered beam 128 in their respective optimally biased state. - As with other implant embodiments, decoupling of k-
wire 60 causes proximalcantilevered beam 126 and distalcantilevered beam 128 to spring outwardly and away from one another and away from the longitudinal axis of throughbore 130 ofbody 124 thereby shortening their lengths so as to apply an active compressive force to the articulating surfaces of the PIP joint. Advantageously,barbs 96 are caused to bite into the bone compressively by the outward force of proximalcantilevered beam 126 and distalcantilevered beam 128 shortening as they move into their respective partially biased state. The biting ofbarbs 96 into the internal bone surfaces at both sides of the joint, coupled with the geometric shortening of both proximal and distal beams, greatly enhances the compressive load exerted byimplant 122 across the joint. Referring toFIGS. 30 and 31 , it will be understood that animplant 122 a may be formed having distal cantileveredbeam 126 a and proximalcantilevered beam 128 a that are arranged on the same side ofbody 124 rather than diagonally as inimplant 122. - Referring to
FIGS. 32-36 ,implant 150 is provided that includes abody 154 and a single pair of cantilevered beams 156 and a mating structure suitable for joiningimplant 150 to atherapeutic device 157 via interconnection withblind bores body 154. More particularly, single pair of cantilevered beams 156 comprise asuperior beam 160 and aninferior beam 162 arranged in spaced confronting relation to one another at an end ofbody 154.Superior beam 160 is fixed to an end ofbody 154, and in some embodiments, is formed integral therewith. One ormore barbs 96 are located on an outer surface ofsuperior beam 160, often oriented transversely across the outer surface. A latch-plate 164 extends inwardly, towardinferior beam 162, from a free end ofsuperior beam 160. Abore 166 is defined through latch-plate 164.Inferior beam 162 is fixed to an end ofbody 154, and in some embodiments, is formed integral therewith. One ormore barbs 96 are located on an outer surface ofinferior beam 162, often oriented transversely across the outer surface. A latch-plate 168 extends inwardly, towardsuperior beam 160 and latch-plate 164, from a free end ofinferior beam 162. Abore 170 is defined through latch-plate 168.Cantilevered beams body 154, i.e., supported or clamped at one end and capable of storing elastic energy when loaded or pre-loaded at the other end or along their length. When cantilevered beams 160, 162 are coupled and preloaded during normal use, they each deflect inwardly. -
Implant 150 is prepared for use in surgery at a variety of orthopedic locations throughout a patient in much the same way asimplant 2. More particularly, single pair ofbeams blind bore 151 b are arranged in substantially coaxial relation to one another. Once in this arrangement, k-wire 60 is inserted throughbore 166, bore 170, andblind bore 151 b, thereby coupling single pair ofbeams implant 2, decoupling of k-wire 60 causes single pair ofbeams barbs 96 are caused to bite into the bone compressively by the outward force of pair ofbeams barbs 96 into the bone greatly enhances the compressive load exerted byimplant 150. - Implants in accordance with the general principles of the foregoing embodiment of the invention may be take a variety of configurations.
