Abstract

The device is composed of three pieces (A,B) the first two being used to fix the large trochanter after installing a hip prothesis. The first piece (A) is a clip with 3 or 4 branches (1) with a socket having a central opening. The piece (B) is a screw whose end (5) has a thread screwed into the housing (6) located at the back of the femoral piece tail near the base of the neck. The other end of the screw is a head (4) which is wider than the socket opening. A third piece which places the first two pieces has a threaded end which is screwed temporarily into the femoral piece whilst its other end is a point which enables drilling the trochanter to place it n a good position. Once the clip slides into this piece it is replaced by the screw.

DISPOSITIF D'OSTEOSYNTHESE DUOSTEOSYNTHESIS DEVICE

GRAND TROCHANTER FIXEFIXED BIG TROCHANTER

SUR LA PIECE FEMORALE D'UNEON THE FEMALE PIECE OF A

PROTHESE TOTALE DE HANCHETOTAL HIP PROSTHESIS

L'ostéotomie du grand trochanter pour l'abord chirurgical de la hanche en vue d'implanter une prothèse totale de hanche est considérée comme la voie la plus sûre, mais aussi la plus controversée du fait des faibles moyens d'ostéosynthèse utilisés, du délai tardif de l'appui et des risques de démontage qui risquent de compromettre le résultat final. Le présent dispositif (fig 1) est un mode d'ostéosynthèse par agrafe (A) dont la particularité est d'être fixée par l'intermédiaire d'une vis (B) au dos de la pièce  The osteotomy of the greater trochanter for the surgical approach of the hip in order to implant a total hip prosthesis is considered as the safest route, but also the most controversial because of the weak means of osteosynthesis used, the delay late support and disassembly risks that may compromise the final result. The present device (fig 1) is a staple osteosynthesis mode (A) whose particularity is to be fixed by means of a screw (B) on the back of the part

fémorale après sa mise en place dans la diaphyse fémorale.  femoral after its placement in the femoral shaft.

Le dispositif de base est composé des deux pièces auxquelles est adjointe une 36e (C) dont la fonction est de placer les pièces A et B. * La pièce A (figure 2), est une agrafe métallique à 3 ou 4 branches (1) dont l'extrémité, est recourbée en bec pour assurer l'ancrage osseux. Le centre de cette pièce est occupé par un orifice (2) prolongé à sa face inférieure d'une douille (3) de  The basic device is made up of two pieces to which is added a 36th (C) whose function is to place pieces A and B. * Piece A (figure 2), is a metal staple with 3 or 4 branches (1) the end of which is curved in a beak to ensure bone anchoring. The center of this part is occupied by an orifice (2) extended at its underside by a socket (3) of

quelques mm de longueur.a few mm in length.

* La pièce B est une vis munie d'une tête (4) dont la caractéristique est d'être plus large que le diamètre d'ouverture de l'orifice (2) de la douille (3) de l'agrafe A. Cet artifice permet par vissage d'exercer un effet de serrage sur l'agrafe A. L'autre extrémité de cette pièce B est munie d'un filetage (5) introduit puis vissé dans le logement (6), muni d'un filetage ménagé au dos de la pièce fémorale (fig 3) à proximité  * The part B is a screw provided with a head (4) whose characteristic is to be wider than the opening diameter of the orifice (2) of the socket (3) of the clip A. This device allows by screwing to exert a clamping effect on the clip A. The other end of this part B is provided with a thread (5) introduced then screwed into the housing (6), provided with a thread on the back of the femoral component (fig 3) nearby

du dos de la base de son col.from the back of the base of his collar.

* La pièce C (figure 4) du système sert à permettre la mise en place de la pièce A: c'est une tige munie à une extrémité (7) d'un filetage identique à celui de la pièce B  * The part C (figure 4) of the system is used to allow the positioning of the part A: it is a rod provided at one end (7) with a thread identical to that of the part B

pour être vissé dans le logement (6) de la pièce fémorale.  to be screwed into the housing (6) of the femoral component.

L'autre extrémité de la pièce C est une pointe (8) utilisée pour perforer le grand  The other end of part C is a point (8) used to perforate the large

trochanter lors de son repositionnement sur la surface d'ostéotomie du fémur.  trochanter during its repositioning on the osteotomy surface of the femur.

Cette tige C est munie d'un étalonnage centimétrique (9) pour mesurer l'épaisseur du grand trochanter. Cette mesure permet ensuite de choisir la longueur adéquate de la vis B.  This rod C is provided with a centimeter calibration (9) to measure the thickness of the greater trochanter. This measurement then makes it possible to choose the appropriate length of screw B.

Z, 2792822Z, 2792822

La pièce C sert donc à perforer le grand trochanter (fig 5 et 6), elle permet aussi de mesurer son épaisseur, de fournir la longueur adéquate de la vis B et enfin de guider la pièce A une fois le médaillon trochantérien abaissé puis accroché sur la pièce C: l'agrafe A est en effet placée en introduisant la douille (3) sur la pointe (8) de la pièce C  The part C therefore serves to perforate the greater trochanter (fig 5 and 6), it also makes it possible to measure its thickness, to provide the adequate length of the screw B and finally to guide the part A once the trochanteric medallion is lowered and then hung on part C: the clip A is in fact placed by inserting the sleeve (3) on the tip (8) of part C

(fig 7).(fig 7).

Après que l'agrafe A soit appliquée sur la surface du grand trochanter (figure 8), la pièce C est enlevée en la dévissant de son logement (6), puis elle est remplacée par la  After the clip A is applied to the surface of the greater trochanter (figure 8), the part C is removed by unscrewing it from its housing (6), then it is replaced by the

vis B de longueur adéquate (figure 9).  screw B of adequate length (figure 9).
