Abstract

The implant, made in one piece e.g. from titanium alloy or a resorbable material, consists of an anterior portion (1) with an anchoring head (3) designed to be inserted and locked axially in the medullary canal of a bone section, and a posterior portion (2) with its body (20) shaped to slide into medullary canal of the bone's other section and be held by sufficient friction to retain the implant in place. The body of the posterior portion has elastic locking surfaces (21) formed by lengthwise grooves (22), to provide the necessary friction forces, especially antirotational.

Description

<B> IMPLANT FOR BONE CHIKE, </ B> <B> AND IN PARTICULAR, </ B> METATARSIEN.

The present invention relates to the field of surgical devices intended to provide bone shortening, in particular of metatarsal bone, for various medical or surgical reasons. The present invention relates to a surgical implant for providing bone shortening and securing two bone parts together.

The present invention also relates to ancillary surgical equipment necessary for the correct placement of the surgical implant in the medial canal of each of the bone parts to be joined after shortening.

In certain pathologies, and for example in foot surgery, the practitioner, namely the surgeon, may have to shorten one or more metatarsals in order to relieve the patient.

It is already known to perform this type of shortening according to several operating techniques. In general, most bone shortening operations, particularly metatarsal bone, are performed at the joint level. This surgical technique, widely used, involves contact and degradation or damage to the integrity of the joint capsules, which, after surgery, causes the patient who has been operated, the appearance of joint stiffness in particular. It is also known the general technique of bone shortening in which the surgeon, after shortening the necessary length of the bone to shorten, secures the two bone parts with a compression staple.

This technique of shortening is not of general application, proves to suffer from disadvantages related to the safety of the maintenance of the solidarized bone parts, and mainly to difficulty placing the staple and the bone parts to be secured with a perfect position. In particular, the use of compression staples makes the placement of bone parts to join extremely difficult when a precise axial direction must be respected between the two bone parts.

The objects assigned to the invention therefore aim at proposing a new surgical implant that does not have the drawbacks of the devices of the prior art and which is easily placed with excellent precision, while providing excellent support for the bone parts to be joined together. .

A complementary object of the invention is to provide a new surgical implant for bone shortening allows good maintenance of the implant and bone parts to be secured and which particularly avoids any risk of relative rotation between the two bone parts. Another object of the invention is to provide a new surgical implant for bone shortening particularly simple to manufacture and to achieve, while being easily adaptable to different types of surgical situations and different sizes of bone. Another object of the invention is to propose a new surgical implant for bone shortening whose implantation in the medullary canal of the bones to be joined is particularly simple.

Another object of the invention is to provide a new surgical ancillary facilitating the establishment of the surgical implant for bone shortening according to the invention, and in particular promoting accurate axial placement of the two bone parts to be joined.

The objectives assigned to the invention are achieved by means of a surgical implant for bone shortening, characterized in that it comprises: an anterior part formed by an anchoring head capable of being inserted and immobilized axially in position in the channel; medulla of a first bony portion, - a posterior portion with a body adapted to be inserted by sliding in the medullary canal of a second bone portion intended to be secured to the first bone part, said body comprising a locking means capable of allow axial insertion of the posterior portion into the medial canal, while exerting sufficient frictional forces against the walls of the medullary canal, once the posterior portion is inserted and in place to lock the implant.

The advantages assigned to the invention are also achieved by means of a surgical ancillary device intended for the placement of a surgical implant for bone shortening according to the invention, characterized in that it is formed by an ancillary device. placing a cannulated surgical implant for bone shortening, characterized by a guide pin (30) for longitudinal threading into the central opening (6) of the implant; ) for receiving and axially locking the guide pin (30) and rotating the posterior portion (2) of the implant which is threaded said guide pin (30), other advantages of the invention will be explained more in detail on reading the description which follows and explanatory drawings provided, solely for explanatory and non-limiting purposes, in which - Figure 1 schematically illustrates a metatarsal bone with mention of the a zone to be removed for shortening.

- Figure 2 illustrates, in a perspective view, an exemplary preferred embodiment of a surgical implant according to the invention.

- Figure 3 illustrates, in a front view, a preferred embodiment of a surgical implant according to the invention.

- Figure 4 illustrates, in a schematic longitudinal sectional view, the establishment of a surgical implant according to the invention in a metatarsal.

- Figure 5 illustrates, in a perspective view, a general view of the components of an ancillary installation according to the invention. - Figure 6 illustrates, in an enlarged perspective view, detail of the end portion of the ancillary of Figure 5.

- Figure 7 illustrates, in a rear perspective view, implant according to the invention, threaded on a guide pin according to the invention.

2 to 4, the surgical implant according to the invention is in the form of a substantially cylindrical oblong element comprising an anterior portion 1 extended directly or indirectly by a posterior portion 2 located in its axial extension. The anterior portion 1 is formed by anchoring head 3 adapted to be inserted and locked axially in position in the medullary cannula 4 of a first bone portion P1 after a bone element P previously shortened.

In general, the surgical implant according to the invention is intended to ensure the shortening of a bone element P (fig), and in particular of a metatarsal bone, from which an intermediate portion M has been removed to obtain two bony parts, respectively head P1, and end P2.

In a conventional manner, the shortening is performed by the practitioner by performing two parallel cuts in the median section of the bone element P, the two cuts being made at a distance corresponding to the length of shortening required by the surgical operation to be performed. In this type of surgical technique, shortening is therefore performed without risk of lesions of the metatarsal joint capsules. The anchoring head 3 may advantageously be provided, at least in its distal portion 5, with a central orifice 6 extending through the entire length of the implant and intended to act as a centering member concentric with the axis. of symmetry of the medial canal 4, cooperation and threading around an ancillary pose placed and provisionally fixed on the head 7 of the first bone portion P1. According to this variant, the implant according to the invention is a cannulated implant. According to the invention, the anchoring head 3 is provided at its periphery with a thread 8, constant or not, allowing its screwing into the medullary canal 4 of the bone part P l.

Advantageously, the anchoring head 3 is self-tapping and comprises, for example, three self-tapping machining operations 10 extending over all or part of the length of the front part 1, starting from the central orifice 6.

Advantageously, the self-tapping machining operations define two active faces 11, 12 to form two faces of variable angular value, and for example of the order of 90, the machining operations being carried out through the thickness of the thread 8 and partly through the root of the anchor head 3.

In the preferred embodiment, illustrated in Figures 2 to 4, the surgical implant according to the invention comprises an intermediate portion 15, preferably smooth and cylindrical, located between the end end of the anchor head 3 and the proximal end the posterior portion 2. The presence of the intermediate portion 15 is optional, the posterior portion 2 may extend directly from the terminal end of the anchor head 3. The presence of a portion However, the smooth intermediate 15 has the advantage of allowing the practitioner some freedom in the depth of implantation of the anchoring head 3.

The posterior portion 2 of the surgical implant according to the invention is in the form of a body 20 of elongated shape extending along the longitudinal axis XX 'of the implant from the end of the intermediate end 15 or alternatively, directly from the anchoring head 3. The body 20 is able to be slidably inserted into the medial canal 4 of the second bone part and to be blocked there, the latter being intended to be joined together with the first bone part P1. To this end, the body 20 comprises locking means 21. Advantageously, the locking means is elastic means 21, capable of deforming in an internal radial direction, in consideration of the longitudinal axis XX 'of the implant to allow and facilitate the axial insertion of the posterior part 2 while ensuring an axial locking and anti-rotation, in the medial canal 4, while exerting sufficient frictional forces against internal walls of the medullary canal 4, once the posterior portion 2 inserted and set up to lock the implant.

According to a preferred variant of the invention, as illustrated in FIGS. 2 to 4, the elastic means 21 is formed by at least a longitudinal slit 22 formed in the body 20, preferably in a median position of the section of the body, and over a length sufficient to form a pair of flexible fins 21A in order to allow a significant radial deformation of the rear portion 2 and the creation of friction forces, and in particular anti-rotation, also significant when the fins 21A are in the elastic rest position free. According to this configuration, the slot 22 may extend over the entire length of the body 21 to the intermediate portion 15, the slot being of sufficient width to allow internal radial deformation two fins 21A resulting from the presence of the slit to allow sufficient elasticity to facilitate insertion.

According to a preferred embodiment illustrated in FIGS. 2 to the elastic means 21 is formed by two longitudinal slots 22 advantageously formed in substantially perpendicular planes along the body 21. According to this preferred configuration, the pair of slots 22 defines four fins 21A on the body 21.

Advantageously, the fins 21A define, in the elastic rest position, a substantially frustoconical volume oriented so that a large base is located towards the terminal end of the posterior portion 2.

To improve the holding of the implant, and especially to improve the rotational locking effect of the second bone portion P2, the rear portion 2 has, at least on the distal portion of the body 20, anti-rotation means made under the shape of a polygonal cross-section, to create blocking edges. Particularly advantageously, the polygonal cross section has a hexagonal section as illustrated in Figures 2 to 4. Other forms of anti-rotation means are of course conceivable.

To improve the ease of insertion of the posterior portion 2, the surgical implant has at the distal portion of the body 20, an inlet chamfer 24, at the end of the four fins 21A for promoting the introduction of the implant into the medial canal 4. To improve the axial and rotational stability, the outer surface of the fins 21A can be shaped to define attachment means, like notches, ribs extending at the periphery posterior portion 2, circumferentially continuous or discontinuous.

The surgical implant according to the invention is thus in the form of a one-piece piece, which can be made, for example, either of metal alloy, of the titanium kind or even of bioabsorbable material.

The establishment of a cannulated surgical implant according to the invention is advantageously carried out using an ancillary laying (Figures 5 to 7) in the form of a pin 30 placed in the center the head of the metatarsal bone of the first bone part P1. Pin 30 is in the form of a solid rod 31, advantageously tapered at its tip and its essential function is to serve as a guide and centering piece during the introduction and screwing of the anchor head 3. Once pin 30 is placed, the practitioner puts the implant, and in particular the anchoring head 3 around the pin through the central orifice 6, which is thus perfectly guided axially. With a cannulated gripping screwdriver 40 in which the posterior portion 2 of the implant is mounted, the anchoring head 3 is screwed into the medial canal 4 of the first bone portion P1 and progresses axially through the self-tapping machining operations 10. that the intermediate portion 15, which serves as a visual cue, comes substantially at the end of the first bone part. In this position, the screwdriver and the spindle are then removed, the posterior portion 2 then being forcefully inserted by elastic deformation of the fins 21A of the body in the medial channel 4 of the second bone piece P2. The fitting continues until the surface joining of the two bone parts P1, P2.

Thus, an ancillary installation of a cannulated surgical implant for bone shortening comprises a guide pin 30 to be threaded longitudinally into the central orifice 6 of the implant. Advantageously, the solid rod 31, substantially cylindrical and made of metal material for example, will be of a diameter substantially equivalent to that of the central orifice 6 forming the cannulation of the implant in order to prevent the internal deformation of the elastic means 21 when the implant threaded into a receiving chamber provided internally in the screwdriver 40. This feature allows the locking rotation of the implant, which allows its screwing and the application of a torque.

The ancillary also comprises a gripping screwdriver 40 cannulated at least in its end portion 41 to form the reception recess for receiving and locking axially by abutment and in rotation the assembly formed by the guide pin 30 on which is threaded the posterior part 2 of the implant.

 Thanks to the surgical implant according to the invention, it is thus possible to easily and extremely accurately position the two bony portions P1, P2, which are axially perfectly aligned, while being both locked together. rotation through the reversible elastic deformation of the rear portion 2. As a complementary variant, it is of course possible to achieve more than four fins 21A level of the body 20.

For purely informational purposes, the respective dimensions of the various parts of a surgical implant according to the invention are for example - anterior part: about mm, - intermediate part: about 2 mm, - posterior part: about 10 mm.

- diameter: - about 4 at the anchor head, -about 3; 3; 4 mm (depending on the implant size) at the posterior part, measured when the posterior part is at rest.
