La présente invention se rapporte au domaine des dispositifs chirurgicaux destinés à assurer le raccourcissement osseux, notamment d'os metatarsien, pour des raisons médicales ou chirurgicales diverses. La présente invention concerne un implant chirurgical pour assurer raccourcissement osseux et la solidarisation de deux parties osseuses entre elles. 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.
La presente invention concerne également les ancillaires équipements chirurgicaux nécessaires à la mise en place correcte l'implant chirurgical dans le canal médulaire de chacune des parties osseuses à solidariser après raccourcissement. 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.
Dans certaines pathologies, et par exemple dans la chirurgie du pied, le praticien, à savoir le chirurgien, peut être amené à raccourcir un ou plusieurs métatarses en vue de soulager le patient. 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.
II est déjà connu de réaliser ce type de raccourcissement selon plusieurs techniques opératoires. De manière générale, la plupart des opérations de raccourcissement osseux, en particulier d'os métatarsiens, s'effectuent au niveau articulaire. Cette technique opératoire, largement répandue, implique un contact et une dégradation ou des lésions de l'intégrité des capsules articulaires, ce qui, après intervention, provoque chez le patient qui a été opéré, l'apparition de ,raideurs au niveau articulaire notamment. On connaît également la technique générale de raccourcissement osseux dans laquelle le chirurgien, après avoir raccourci de la longueur nécessaire la partie osseuse à raccourcir, assure la solidarisation des deux parties osseuses à l'aide d'une agrafe à compression. 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.
Cette technique de raccourcissement n'est pas d'application générale, s'avère souffrir d'inconvénients liés à la sécurite du maintien des parties osseuses solidarisées, et principalement à difficulté de mise place de l'agrafe et des parties osseuses à solidariser avec une position parfaite. En particulier, le recours à des agrafes à compression rend la mise en place des parties osseuses à solidariser extrêmement difficile lorsqu'une direction axiale précise doit être respectée entre les deux parties osseuses. 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.
Les objets assignés à l'invention visent en conséquence à proposer un nouvel implant chirurgical ne présentant pas les inconvénients des dispositifs de l'art antérieur et qui soit facilement mis place avec une excellente précision, tout en procurant un excellent maintien des parties osseuses à solidariser. 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. .
Un objet complémentaire de l'invention vise à proposer un nouvel implant chirurgical pour raccourcissement osseux permette un bon maintien de l'implant et des parties osseuses à solidariser et qui évite en particulier tout risque de rotation relatif entre les deux parties osseuses. Un autre objet de l'invention vise à proposer un nouvel implant chirurgical pour raccourcissement osseux particulièrement simple à fabriquer et à réaliser, tout en étant facilement adaptable à différents types de situations chirurgicales et à différentes tailles d'os. Un autre objet de l'invention vise à proposer un nouvel implant chirurgical pour raccourcissement osseux dont l'implantation dans le canal médulaire des os à solidariser est particulièrement simple. 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.

que cela est représenté aux figures 2 à 4, l'implant chirurgical conforme à l'invention se présente sous la forme d'un élément oblong, sensiblement cylindrique comportant une partie antérieure 1 prolongée directement ou indirectement par une partie postérieure 2, située dans son prolongement axial. La partie antérieure 1 est formée par tête d'ancrage 3 apte à être insérée et bloquée axialement en position dans le canai médulaire 4 d'une première partie osseuse P1 issue d'un élément osseux P au préalable raccourci. 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.
D'une manière générale, l'implant chirurgical conforme à l'invention est destiné à assurer le raccourcissement d'un élément osseux P (fig ), et en particulier d'un os métatarse, dont on a retiré une portion intermédiaire M pour obtenir deux parties osseuses, respectivement de tête P1, et d'extrémité P2. 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.
De manière classique, le raccourcissement est effectué par le praticien en effectuant deux coupes parallèles dans la section mediane de l'élément osseux P, les deux coupes étant réalisées à distance correspondant à la longueur de raccourcissement requise par l'opération chirurgicale à effectuer. Dans ce type de technique opératoire, le raccourcissement est donc réalisé sans risques de lésions des capsules articulaires du métatarse. La tête d'ancrage 3 peut être avantageusement pourvue, au moins dans sa partie distale 5, d'un orifice central 6 s'étendant à travers toute la longueur de l'implant et destiné à servir d'organe centrage concentrique à l'axe de symétrie du canal médulaire 4, coopération et enfilement autour d'un ancillaire de pose mis en place et fixé provisoirement sur la tête 7 de la première partie osseuse P1. Selon cette variante, l'implant conforme à l'invention est un implant canulé. Selon l'invention, la tête d'ancrage 3 est pourvue à sa périphérie d'un filetage 8, constant ou non, permettant son vissage dans le canal médullaire 4 de la partie osseuse P l. 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.
Avantageusement, la tête d'ancrage 3 est autotaraudeuse et comprend par exemple trois usinages autotaraudants 10 s'étendant sur tout ou sur une partie de la longueur de la partie antérieure 1, à partir de l'orifice central 6. 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.
De manière avantageuse, les usinages autotaraudants définissent deux faces actives 11, 12 pour former deux pans d'une valeur angulaire variable, et par exemple de l'ordre de 90 , les usinages étant réalisés à travers l'épaisseur du filetage 8 et en partie à travers la racine de la tête d'ancrage 3. 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.
Dans l'exemple de réalisation préférentielle, illustré aux figures 2 à 4, l'implant chirurgical selon l'invention comporte une partie intermédiaire 15, de préférence lisse et de forme cylindrique, située entre l'extrémité terminale de la tête d'ancrage 3 et l'extrémité proximale la partie postérieure 2. La présence de la partie intermédiaire 15 est optionnelle, la partie postérieure 2 pouvant s'étendre directement à partir de l'extrémité terminale de la tête d'ancrage 3. La présence d'une partie intermédiaire lisse 15 a néanmoins pour avantage de laisser une certaine liberté au praticien quant à la profondeur d'implantation de la tête d'ancrage 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.
La partie postérieure 2 de l'implant chirurgical conforme à l'invention se présente sous la forme d'un corps 20 de forme allongée etendant selon l'axe longitudinal XX' de l'implant à partir de l'extrémité terminale de la partie intermédiaire 15 ou selon une variante, directement à partir de la tête d'ancrage 3. Le corps 20 est apte à être inséré par coulissement dans le canal médulaire 4 de la seconde partie osseuse et à y être bloqué, cette dernière étant destinée à être solidarisée avec la première partie osseuse P1. A cette fin, le corps 20 comprend moyen de blocage 21. Avantageusement, le moyen de blocage est moyen élastique 21, susceptible de se déformer selon un sens radial interne, en considération de l'axe longitudinal XX' de l'implant pour permettre et faciliter l'insertion axiale de la partie postérieure 2 tout en assurant un blocage axial et anti-rotation, dans le canal médulaire 4, tout en exerçant des forces de frottement suffisantes contre parois internes du canal médulaire 4, une fois la partie postérieure 2 insérée et mise en place pour assurer le blocage de l'implant. 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.
Selon une variante préférentielle de l'invention, telle illustrée figures 2 à 4, le moyen élastique 21 est formé par au moins fente longitudinale 22 ménagée dans le corps 20, de préférence selon une position médiane de la section du corps, et sur une longueur suffisante former une paire d'ailettes flexibles 21A en vue de permettre une deformation radiale significative de la partie postérieure 2 et la création forces de frottement, et en particulier d'anti-rotation, également significatives lorsque les ailettes 21A sont en position de repos elastique libre. Selon cette configuration, la fente 22 peut s'étendre sur totalité de la longueur du corps 21 jusqu'à la partie intermédiaire 15, la fente étant d'une largeur suffisante pour permettre une déformation radiale interne deux ailettes 21A résultant de la présence de la fente afin de permettre une élasticité suffisante pour faciliter l'insertion. 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.
Selon variante de réalisation préférentielle illustrée aux figures 2 à le moyen élastique 21 est formé par deux fentes longitudinales 22, ménagées avantageusement selon des plans sensiblement perpendiculaires le long du corps 21. Selon cette configuration préférentielle, la paire de fentes 22 définit quatre ailettes 21A sur le corps 21. 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.
Avantageusement, les ailettes 21A définissent, en position de repos élastique, un volume sensiblement tronconique orienté pour que grande base soit située vers l'extrémité terminale de la partie postérieure 2. 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.
Pour améliorer la tenue de l'implant, et notamment pour améliorer l'effet de blocage en rotation de la seconde partie osseuse P2, la partie postérieure 2 présente, au moins sur la partie distale du corps 20, moyens anti-rotation réalisés sous la forme d'une section transversale polygonale, afin de créer des arêtes de blocage. De manière particulièrement avantageuse, la section transversale polygonale présente une section hexagonale telle qu'illustré aux figures 2 à 4. D'autres formes de moyens anti-rotation sont bien évidemment envisageables. 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.
Pour améliorer la facilité d'insertion de la partie postérieure 2, l'implant chirurgical présente au niveau de la partie distale du corps 20, un chanfrein d'entrée 24, au niveau de l'extrémité des quatre ailettes 21A destiné à favoriser l'introduction de l'implant dans le canal médulaire 4. Pour ameliorer la stabilité axiale et en rotation, la surface externe des ailettes 21A peut être conformée pour définir des moyens d'accrochage, du genre encoches, nervures s'étendant à la périphérie partie postérieure 2, de manière circonférencielle continue ou discontinue. 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.
L'implant chirurgical selon l'invention se présente ainsi sous forme d'une pièce monobloc, qui peut être réalisée, à titre d'exemple, soit en alliage métallique, du genre titane ou bien encore en matériau biorésorbable. 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.
La mise en place d'un l'implant chirurgical canulé selon l'invention s'effectue avantageusement à l'aide d'un ancillaire de pose (figures 5 à 7) se présentant sous la forme d'une broche 30 mise en place au centre la tête de l'os métatarsien de la première partie osseuse P1. La broche 30 se présente sous la forme d'une tige pleine 31, avantageusement effilée à sa pointe et a pour fonction essentielle de servir de pièce de guidage et de centrage lors de l'introduction et du vissage de la tête d'ancrage 3. Une fois la broche 30 posée, le praticien enfile l'implant, et en particulier la tête d'ancrage 3 autour de la broche à travers l'orifice central 6, qui se trouve ainsi parfaitement guidé axialement. Grâce à un tournevis de préhension canulé 40 dans lequel la partie postérieure 2 de l'implant est montée, la tête d'ancrage 3 est vissée dans le canal médulaire 4 de la première partie osseuse P1 et progresse axialement grâce aux usinages autotaraudants 10 jusqu ce que la partie intermédiaire 15, qui sert de repère visuel, vienne sensiblement au niveau de l'extrémité de la première partie osseuse . Dans cette position, le tournevis et la broche sont alors retirés, la partie postérieure 2 étant alors inséree en force par déformation élastique des ailettes 21A du corps dans le canal médulaire 4 de la seconde pièce osseuse P2. L'emmanchement se poursuit jusqu'à la solidarisation surfacique des deux parties osseuses P1, P2. 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.
Ainsi, un ancillaire de pose d'un implant chirurgical canulé pour raccourcissement osseux comporte une broche de guidage 30 destinée à être enfilée longitudinalement dans l'orifice central 6 de l'implant. Avantageusement, la tige pleine 31, sensiblement cylindrique et réalisée en matériau métallique par exemple, sera d'un diametre sensiblement équivalent celui de l'orifice central 6 formant la canulation de l'implant afin d'empecher la déformation interne du moyen élastique 21 lorsque l'implant enfilé dans un chambrage de réception prévu intérieurement dans le tournevis 40. Cette particularité permet le blocage rotation de l'implant, ce qui autorise son vissage et l'application d'un couple de rotation. 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.
L'ancillaire comporte également un tournevis de préhension 40 canulé au moins dans sa partie terminale 41 pour constituer le chambrage de réception destiné à recevoir et à bloquer axialement par butée et en rotation l'ensemble formé par la broche de guidage 30 sur laquelle est enfilée la partie postérieure 2 de l'implant. 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.
Grâce à l'implant chirurgical conforme à l'invention, il est ainsi possible de positionner facilement et de manière extrêmement précise les deux parties osseuses P1, P2, qui sont axialement parfaitement alignées, tout en étant bloquées l'une et l'autre en rotation grâce à la déformation élastique réversible de la partie postérieure 2. A titre de variante complémentaire, il est bien évidemment possible de réaliser plus de quatre ailettes 21A niveau du corps 20. 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.
A titre purement informatif, les dimensions respectives des différentes parties d'un implant chirurgical conforme à l'invention sont par exemple -partie antérieure: environ mm, - partie intermédiaire: environ 2 mm, - partie postérieure : environ 10 mm. 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.
- diamètre : - environ 4 au niveau de la tête d'ancrage, -environ 3 ; 3 ; 4 mm (selon les tailles d'implant) au niveau de partie postérieure, valeur mesurée lorsque la partie postérieure est en repos libre.- 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.
