Principle of diaphyseal modularity, with high mechanical strength, adaptable to any hip prosthesis

摘要

The hip prosthesis according to the invention comprises an elongate body having a cervical part (C) supporting a spherical head (5) which is intended to engage in an acetabular cavity, a diaphyseal part (D) forming a cervical/diaphyseal angle with the cervical part, and a metaphyseal region (M) of bent shape. The diaphyseal part (D) has the shape of a rod (6) which is rigidly integral with the metaphyseal part (M) and on which there may be engaged a removable and interchangeable diaphyseal sleeve (8, 8'), the outer surface of which has a shape substantially complementary to that of the said femoral cavity. The invention makes it possible to limit the number of shapes of bodies included in one series. <IMAGE>
