Description

L'invention concerne un ensemble prothétique pour larticulation du genou A prosthetic assembly for the knee larticulation
L'objet de l'invention se rattache au secteur technique des sciences médicales. The object of the invention relates to the technical field of medical sciences.

Il est connu d'employer pour certaines lésions du ge nou, des prothèses destinées à reconstituer l'articulation entre le fémur et le tibia. It is known to use certain lesions nou age, prostheses designed to restore the joint between the femur and tibia. Généralement, ce type de prothèses est limité en nombre ; Generally, this type of prostheses is limited in number; on distingue essentiellement les prothèses trochléo-bicondyliennes monoblocs, les prothèses rotuliennes et les prothèses mono-compartimentaires.Cette limitation en nombre et en forme des prothèses, engendrent certains inconvénients car, en fonction de la lésion à traiter, on peut utiliser seulement le type le plus rapprochant de prothèse de sorte que le résultat obtenu ne peut pas Btre jugé satisfaisant there are essentially monobloc trochléo-bicondylar dentures, prosthetics and patellar prosthesis single-compartimentaires.Cette limitation in number and shape of the prosthesis, cause some inconveniences because, according to the lesion to be treated, only one can use the type more closer prosthesis so that the result is not satisfactory BTRE
En effet, ou bien la prothèse est sous-adaptée au traitement du genou à effectuer ou bien la prothèse est SU- adaptée au traitement à effectuer susceptible d'affecter ainsi les zones non endommagées. Indeed, or the prosthesis is sub-suited to the treatment of the knee to make or SU- the prosthesis is adapted to processing to be performed and may affect non-damaged areas. Par exemple, les prothèses monocompartimentaires ne sont pas conformées pour entre adaptées soit au condyle interne soit au condyle externe De même il n'existe aucune prothèse trochléo-condylienne interne et externe. For example, monocompartimentaires prostheses are not shaped to be adapted between the medial condyle is the lateral condyle Similarly there is no trochléo-condylar internal and external prosthesis.

Le problème étant ainsi posé, l'invention s'est fixée pour but de décomposer, et de moduler, le genou en plusieurs parties correspondant aux différentes lésions possibles et de réaliser, pour chacune de ses parties, une prothèse particuliè- rement bien adaptée en forme et di-mension. The problem is thus posed, the invention is set for purpose of breaking down and to adjust the knee into several portions corresponding to different possible lesions and realize, for each of its parts, a particu- surely prosthesis well adapted form and di-mension.

Dans ce but, on exécute une nouvelle prothèse trochléo- bicondylienne monobloc dont les formes et profils sont déterminés pour s'adapter a l'anatomie du genou notamment du fémur con sidéré selon un échantillon représentattif. For this purpose, it performs a new trochléo- intercondylar monobloc prosthesis whose shapes and profiles are determined to adapt to the anatomy of the knee including con femur stunned in a représentattif sample. À partir de cette prothèse de base qui est convenablement équipée de plots d'ancrage, on réalise : - une prothèse trochléo-condylienne externe, - une prothèse trochléo-condylienne interne, - une prothèse mono-externe, - une prothèse mono-interne, - une prothèse rotulienne. From this basic prosthesis which is suitably equipped with anchor studs, are carried out: - an outer trochléo-condylar prosthesis, - an inner trochléo-condylar prosthesis, - a single external prosthesis, - a mono-internal prosthesis, - a patellar prosthesis.

On a ainsi réalisé un ensemble comprenant pour chaque genou six types différents de prothèses correspondant chacun à la lésion à traiter. There was thus produced a set comprising for each knee six different types of prostheses, each corresponding to the lesion to be treated. D'une manière préférée, chaque type existe en trois tailles : une grande, une petite, une moyenne. In a preferred way, each type comes in three sizes: large, small, medium.

L'invention est exposée ci-après plus en détail a l'aide des dessins qui représentent les formes et profils de chaque type de prothèse, étant souligné que les prothèses illustrées correspondent au genou droit et sont illustrées à l'échel- le 1 correspondant a la grande taille. The invention is described below in more detail with the aid of drawings which represent the shapes and profiles of each type prosthesis is emphasized that the illustrated prostheses correspond to the right knee and are illustrated échel- the corresponding 1 has great size.

La prothèse trochléo-bicondylienne monobloc illustrée figures 1 à 4 comprend une partie (1) qui fait office de bouclier rotulien, prolonge dans un plan perpendiculaire ou sensiblement perpendiculaire par demi-lobes profilés (2) et (3) sépa- rés par une échancrure (4) laissant subsister une partie commune (5) entre lesdits lobes (2) et (3). The monobloc trochléo-intercondylar prosthesis illustrated in Figures 1 to 4 comprises a part (1) which acts as a patellar shield, extends in a plane perpendicular or substantially perpendicular half-lobe profiles (2) and (3) sepa- rated by a notch (4) leaving a joint portion (5) between said lobes (2) and (3). Dans le cas du genou droit, le lobe (2) est profil en section pour correspondre au rayon moyen de courbure du condyle interne. In the case of the right knee, the lobe (2) is cross-sectional profile to match the mean radius of curvature of the medial condyle. Inversement, le lobe (3) est profilé en section pour correspondre en section au rayon de courbure moyen du condyle externe. Conversely, the lobe (3) is profiled in section to correspond in section with radius of curvature of the lateral condyle.

La prothèse trochléo-condylienne interne (figures 5, 6, 7 et 8) comprend le bouclier rotulien (1) prolongé d'un coté seulement, dans un plan perpendiculaire ou sensiblement perpendiculaire, par le lobe (2) dont le profil en section correspond au rayon de courbure moyen du condyle interne. Trochléo the inner-condylar prosthesis (Figures 5, 6, 7 and 8) comprises the patellar shield (1) extended on one side only, in a plane perpendicular or substantially perpendicular, with the lobe (2) whose sectional profile is the mean radius of curvature of the medial condyle. A l'opposé du lobe (2), la partie commune t5) est coupée en biseau (ó) selon un angle déterminé correspondant à la course rotulienne normale. In contrast to the lobe (2), the common part t5) is bevelled (O) according to a determined angle corresponding to the normal patellar race.

La prothèse trochl#o-condylienne externe Figures 9 10, 11 et 12) est semblable à la prothèse trochléo-condyli#nne interne, la seule différence résidant dans l'implantation du lobe (3) et de la coupe en biseau (7) qui sont inversés. The prosthesis trochl # o-condylar external Figures 9 10, 11 and 12) is similar to the prosthesis # condyli trochléo-detached house, the only difference being in the implementation of the lobe (3) and the bevel (7) which are reversed.

La prothèse rotulienne (figures 21, 22, 23 et 24) est réalisée à partir du bouclier condylien (d) prolongé dans un plan perpendiculaire ou sensiblement perpendiculaire, par la partie commune (5) dont les extrémités latérales (8) et (9) sont coupées en biseau pour correspondre respectivement à la course rotulienne externe et interne. The patellar prosthesis (Figures 21, 22, 23 and 24) is made from the condylar shield (d) extended in a plane perpendicular or substantially perpendicular, by the common part (5) whose side ends (8) and (9) are cut diagonally to match the patellar outer and inner race respectively.

D'une manière importante, la longueur du bouclier rotulien (1) est déterminée pour recevoir toutes les anatomies possibles (rotules hautes ou basses). Importantly, the length of the patellar shield (1) is determined to receive all the possible anatomies (high or low ball).

La prothèse mono-externe montrée figures 13, 14, 15 et 16 comprend seulement le lobe (3) dont le profil en section cor respond au rayon de courbure moyen du condyle externe. The mono-external prosthesis shown in Figures 13, 14, 15 and 16 only includes the lobe (3) whose profile horn section sponds to the average radius of curvature of the lateral condyle. lsin- verse, la prothèse mono-interne montrée figures 17, 15, 19 et 20, comprend seulement le lobe (2) dont le profil en section correspond au rayon de courbure moyen du condyle interne. lsin- poured, mono-internal prosthesis shown in Figures 17, 15, 19 and 20, includes only the lobe (2) whose sectional profile is the average radius of curvature of the medial condyle.

D'une manière importante, chaque prothèse présente directement ou d'une manière rapportée, en fonction de la nature du matériau la composant, des plots d'ancrage (10). Importantly, each prosthesis has directly or an insert manner according to the nature of the material of the component, the anchor studs (10). Ces plots sont convenablement positionnés en débordement de la face interne des prothèses pour résister aux différentes parties de pression auxquelles est soumise la prothèse. These pads are suitably positioned protruding from the inner face of the prosthesis to withstand the various parts of pressure which is subject the prosthesis.

Selon l'invention, pour chaque type de prothèse, les plots (10)- ont la même implantation et la m#me forme. According to the invention, for each type of prosthesis, the studs (10) - have the same layout and shape me # m. Deux plots sont formés en débordement de la face interne de chacun des lobes (2) et (3), tandis qu'un plot est formé en débordement de la face interne de la partie commune (5) relative au bouclier rotulien. Two pads are formed protruding from the inner face of each of the lobes (2) and (3), while a pad is formed protruding from the inner face of the common part (5) on the patellar shield. La longueur du plot du bouclier rotulien est supérieure à celle des plots relatifs aux lobes (2) et (3). The length of the patellar pad of the shield is higher than that of the studs relative to the lobes (2) and (3).

Les plots d'ancrage des lobes (2) et (3) sont séparés et eventuellement prolongés latéralement par des toiles entretoisées (11). The anchoring pins of the lobes (2) and (3) are separated and optionally extended laterally braced by webs (11).

Selon l'invention, on a donc créé six types de prothè- ses pour chacun des genoux, chaque type étant réalisé de prXf6- rence en trois tailles, soit au total 36 prothèses. According to the invention, so we created six types of prosthesis for each lap, each type being designed prXf6- ence in three sizes, totaling 36 implants.

L'invention ne se limite aucunement à celui de ses modes d'applications non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; The invention is in no way limited to that of its modes of application not only to those embodiments of its various parts have been especially appropriate; elle en embrasse au contraire toutes les variantes. it encompasses all variants.
