Abstract
An interlocking reversed hip prosthesis including an acetabular cup being implanted in the acetabular cavity having an acetabular articular ball, firmly attached to the central portion of the cup via Morse taper. The femoral component having a hemispherical cup attached to the neck of the implant via Morse taper in a modular fashion thereby allowing use of several length necks. After implantation of the acetabular cup and the femoral cup, the two members are assembled together for relative movement. The acetabular cup secured by several screws or resorbable fixation studs. During range of motion, the edge of the femoral cup becomes inserted into space located between the acetabular cup and the acetabular ball and becomes restrained thus reducing the likelihood of dislocation during extreme range of motion.
