Abstract

The cotyloidal prosthesis comprises of a cup (100) that has a peripheral groove located on its outside edge. A ribbed band (200) is located in this groove. The band and the cup section have aligned holes (104,105,204,202)through which a retention clips (300) can be located to secure the band and cup.

A cet effet, l'invention concerne une prothèse du type défini ci-dessus, caractérisée en ce que la ceinture est munie à chaque extrémité, d'un perçage sensiblement parallèle à l'axe de la cupule et le bord de la cupule est traversé par deux perçages dans une position correspondant à celle des perçages des extrémités de la ceinture lorsque ces extrémités sont en position enfoncée dans la gorge, pour recevoir une broche de verrouillage en forme de U. La fixation de la ceinture en position escamotée par une broche en forme de U, dont une branche est logée dans chacun des perçages du bord de la cupule et dans le logement  To this end, the invention relates to a prosthesis of the type defined above, characterized in that the belt is provided at each end with a bore substantially parallel to the axis of the cup and the edge of the cup is crossed by two holes in a position corresponding to that of the holes in the ends of the belt when these ends are in the sunken position, to receive a U-shaped locking pin. The fixing of the belt in the retracted position by a pin in U-shaped, one branch of which is housed in each of the holes in the edge of the cup and in the housing

This extraction is done with pliers. There is therefore no risk of losing the spindle. Finally, the operation is done in the axis of the acetabulum, that is to say in the direction of the most
