Title (EN) POLYETHYLENE HIP JOINT PROSTHESIS WITH EXTENDED RANGE OF MOTION
(FR) PROTHESE DE HANCHE EN POLYETHYLENE AVEC AMPLITUDE ARTICULAIRE ACCRUE
Abstract:
(EN) A hip joint prostheses including an acetabular cup (2) mounted in the hip socket (4) of the pelvis (6) is disclosed. The prosthesis also includes a head (8) which has a radius of curvature complementary to the cavity in the acetabular cup (2). The head (8) is typically made of metal. A neck (10) is connected to the head (8) joining the head (8) to the stem (12). The head (8), and the acetabular cup (2) are designed to allow a great deal of angular articulation. The bearing portions can be made with radiation treated ultrahigh molecular weight polyethylene polymer having substantially no detectable free radicals.
(FR) Cette invention se rapporte à une prothèse de hanche, comprenant un cotyle (2) monté dans la cavité articulaire (4) du bassin (6). Cette prothèse comprend également une tête (8) possédant un rayon de courbure complémentaire de la cavité du cotyle (2). Cette tête (8) est généralement fabriquée en métal. Un col (10) est relié à la tête (8), joignant la tête (8) à la tige (12). La tête (8) et le cotyle (2) sont conçus pour permettre une grande amplitude des mouvements angulaires. Les parties d'appui peuvent être fabriquées en polymère de polyéthylène à poids moléculaire très élevé, traité par rayonnement et ne contenant pour ainsi dire pas de radicaux libres détectables.
