Abstract

Disclosed is a bone fusion or implant, method and system for arthrodesis of a human ankle fusing the distal end of a tibia, talus and/or a calcaneus bone by employing a single anatomically lateral incision to the tibia, fibula, talus and calcaneus region, removing some or all of a fibula in the incision area and attaching the implant to the tibia, talus and/or calcaneus in a generally central area of the ankle. The removed portion of the fibula is morsilized and made into a paste and mixed with an autologous platelet concentrate that is applied as a bone graft to the implant site thereby enhancing the arthrodesis site and enhancing hemostasis.

Description

Disclosure

Tibia-Talus-Calcaneus (T-T-C) Locking Plate

Field of Disclosure

The field of the present invention relates to a method and device for repairing or fusing damaged, deteriorating, or fractured tibia, talus and calcaneus bones in the ankle region. More particularly, the present invention relates to both a method and device for treating tibia, talus and/or calcaneus bones that are affected by illness or injury using lateral incision(s) and joint fusion(s).

Background of Disclosure

Implants are foreign devices which may be inserted into any bone. The utilization of implants in the treatment of bone fractures with plates, screws, intramedullary nails and rods are well known to those in the art. Various types of implants exist in the prior art, each composed of different materials and having different shapes with various degrees of functionality.

Intramedullary nails are adapted for insertion into the medullary canal of a bone or bones. Intramedullary nails have been limited in their application to long or large bones and such use has been widely known for long or large bones of the upper extremities (humerus, radius, ulna) and lower extremities (femur, tibia, fibula). Use of intramedullary nails allows physicians to secure fractured bones, maintain a desired length, and prohibit rotary motion while the bone heals and has time to rehabilitate. Intramedullary nails are also used for the fusion of bones. In an arthrodesis model the tibia, talus and calcaneus fracture repair failed at lower loads over time, resulting in cracks or breaks, as compared to blade. (Chiodo, Christopher P., Acevedo, Jorge L, Sammarco, V. James, Parks, Brent G., Boucher, Henry R., Myerson, Mark S., Schon, Lew C; "Intramedullary Rod Fixation Compared with Blade-Plate-and-Screw Fixation for Tibiotalocalcaneal Arthrodesis: A Biomechanical Investigation"; The Journal of Bone & Joint Surgery, Vol. 85- A, Number 12, Pgs.2425-2428, December 2003)

Plates that incorporate a series of holes for screw insertion are also typical implants for the fixation of bones and joints. Plates to be used may be linearly straight or may have some curvatures or undulations, depending on the anatomical location and bone size. These curvatures or undulations are for placement for conforming to the bone circumferential shape and/or diameter. The hole positioning may provide for straight or angular insertion of the fasteners or screws that are to be used. Fasteners generically , include all attaching means by which an implant may be attached to or connected with bone.

Such fasteners are inserted through a fastener hole or slot, also described as transfixation holes and screw holes. The use of plate locking screws is optional depending upon the severity of the bone damage. Static locking, by insertion of screws in proximal and distal locations, neutralizes rotational stresses while preventing shortening of the limb.

Generally, tibiotalocalcaneal fixation with plates requires either anterior and/or posterior incision and anterior and/or posterior placement of the respective implant device in relation to the T-T-C interface. One risk factor involving anterior implantation is that the implant is placed close to the skin and therefore there is increased risk of wound dehisence, and ultimately, removal of the implant.

While there is much in the art regarding implants, there is a need for a lower infection risk implant and method for arthrodesis of the T-T-C region of a human foot. Such an implant and procedure may likely have any or all of the similar properties, features, and characteristics of the above mentioned implant methodologies, but greatly reduces the risk of wound dehisence by providing an implant that is further from the skin surface than the present anterior implant methodologies.

Detailed Description of the Drawings

Figure IA is an isometric view of a T-T-C implant [100] showing the holes [105] which may have internal threads [110] for a locking feature [115] that would lock a fastener [120] (Ref. Figure 1C) to the implant [100]. The holes [105] may be perpendicular to the longitudinal surface [125] of the implant [100] or may be angled to provide a fastener direction of various configurations that are overlapping, parallel, divergent or convergent.

The implant [100] also has a distal end [130] that is larger than the longitudinal plane [125] that is angled at, or about, thirty degrees within a range of fifteen to forty five degrees. The distal end [130] also contains holes [105] of various configurations that provide direction for a fastener [120] that are overlapping, parallel, divergent or convergent. The implant [100] is made of a biocompatible material that would typically be titanium or stainless steel and be malleable to be shaped to meet the contours and undulations of a patients bone structures and shapes.

Figure IB is an isometric view of a T-T implant [155] which has a distal end that is angled at ninety-degrees to the longitudinal plane [125].

Figure 1C is an isometric view of a fastener [120], in this case a typical orthopaedic screw [135]. The screw [135] has a wide spiral thread [140] for insertion into a bone and a narrow external thread [145] at the head [150] that secures with the hole internal threads [110] (Ref. Figure IA) of the implant [100] (Ref. Figure IA).

Figure 2 A is a lateral skeletal view of the right foot [200] showing the distal end of the tibia [205], distal end of the fibula [210], talus [215] and calcaneus [220] as well as the midfoot region [225] and phalanges [230].

Figure 2B is a lateral skeletal view of the right foot [200] showing the implant [100] fastened to the tibia [205], talus [215] and calcaneus [220] using screws [135] to secure the implant [100]. A portion of the fibula [210] is shown removed allowing for access to the lateral aspect of the tibia [205] as well as the implant [100] being centrally located within the distal portion of the leg away from the skin (not shown).

The portion of the fibula [210] which has been removed is ground or pulverized to form a cortical-calcaneous bone graft packing [240] (not shown) that may be mixed with an autologous platlet concentrate and packed over the fastened implant [100] to aid in hemostasis. The lateral fastening of the implant [100] acts to secure, or fuse, the tibia [205], talus [215] and calcaneus [220] and act as an implant and stabilize the fusion of the skeletal structure.

Figure 2C is a lateral skeletal view of the right foot [200] showing the implant T-T [155] fastened to the tibia [205] and talus [215] only. An alternative method would be to reshape the implant [100] to secure the tibia [205] and calcaneous [220] should the talus [215] be removed.

Figure 3 is an anterior view of the tibia [205], talus [215] and calcaneus [220] showing the implant [100] and phantom views of potential locations of the fasteners [120] or screws [135] within the T-T-C region. The fibula [210] is partially removed.

Overview of Surgical Technique for T-T-C (Tibial-Talar-Calcaneal), T-T (Tibial- Talar) and T-C (Tibial-Calcaneal) Arthrodesis

In the present disclosure the patient is placed on the operating room table in the supine (face up) position. As prior art, the posterior approach to T-T-C arthrodesis requires a prone position (face down) which is more dangerous for the patient from an anesthesia perspective. It is also more difficult to align the patient's lower extremity in the correct position with the patient face down.

An extensive anatomically lateral incision is performed over the fibula exposing the distal twelve (12) to fourteen (14) centimeters of the fibula. This section of fibula is surgically removed and cleaned of all soft tissue. The fibula section is then morsilized and mixed with autologous platelet concentrate to form a bone graft for additional healing in the arthrodesis site. The posterior approach requires a second surgical site for harvesting bone graft frequently from the hip.

The T-T-C, T-T or T-C joint surfaces are debrided of all articular cartilage so raw bone is exposed for the arthrodesis. If the talus exhibits avascular necrosis or is destroyed, a tibial-calcaneal arthrodesis can be performed either without an interpositional graft or with an interpositional graft such as a femoral head in order to maintain length of the extremity.

The foot is placed in alignment with the second metatarsal aligned with the tibial crest and the ankle at zero degrees of dorsiflexon. A temporary Steinman pin is placed from the plantar aspect of the heel into the distal tibia. X-rays are taken at this time to check alignment. Cannulated screws are placed from the distal tibial metaphysis across the arthrodesis sites to get compression. One cannulated screw is placed from the distal anterior tibia into the calcaneus posteriorly. The second screw is placed from the posterior tibia into the medial column of the foot. Placement of these screws are performed under fluoroscopic guidance and through the single lateral incision site.

The lateral T-T-C, T-T or T-C locking plate implant is contoured to the patient's anatomy. A large fixed angle locking screw is placed first into the sustentaculum of the calcaneus which is the densest part of the bone. Polyaxial screws are then placed for additional fixation into the calcaneus. For additional compression a non-locking screw can be placed by eccentric drilling or a compression device can be applied to the tibia and plate. The remaining fixed angle locking screws are inserted and secured. Fluoroscopic evaluation is performed to check screw lengths and alignment.

The bone graft that was harvested from the fibula and processed is used to fill in any deficits and placed posteriorly through the lateral incision for an extra-articular arthrodesis. The tissues are closed in layers and a drain is placed to prevent postoperative hematoma. Removal the fibula ensures there is adequate soft tissue coverage of the locking plate. An anterior approach with a locking plate manufactured by Synthes has very little soft tissue coverage which can lead to wound dehiscence or pain from the hardware. A post-operative dressing is placed along with a posterior splint. The drain is left in for 24 to 48 hours. Dressings are changed and the patient is placed into a nonweight bearing fracture brace until healing has occurred on X-ray. Healing time is approximiately six to twelve weeks.
