Abstract
A hip joint prosthesis consisting of an artificial femur head and an artificial acetabular socket. The femur head includes a ball head which is received in the acetabular socket, a neck connecting the ball head to a platform and an arcuate stem which is T-shaped in cross section and extends from the platform for insertion into the medullar cavity in a femur. A recess located on the lateral portion of the platform and several steps located along the medial portion of the stem are further provided to securely anchor the prosthesis when it is cemented into the medullar cavity.
