Two-part joint prosthesis

Abstract

Abstract The aim of the invention relates to the technical sector of the medical sciences. According to the invention, the inner tibial plate (1) has directly, or has added to it, a guiding and positioning means (3) of which one part cooperates with a complementary notch (A) made anteriorly in the thickness of the body of the tibial spinous processes, being capable of extending beyond the said body into the outer compartment, the said part being arranged to receive a marking member (6) capable of cooperating with the inner edge of the outer condyle at a 90 DEG flexion of the knee so as to indicate an angular cut (C) to be made on the corresponding side of the body of the tibial spinous processes as a function of the rotational effect produced by the tibia relative to the femoral condyles, with a view to ensuring the angular positioning of the outer plate (2) bearing on the resected side of the body, the said outer plate being arranged to receive, with possibility of angular adjustment, a complementary guiding and positioning means (4) capable of cooperating with the means (3) in order to position the bearing surface of each of the inner and outer plates in the same horizontal plane. <IMAGE>
