Abstract
A hip joint prosthesis includes a first member having a shaft portion and a lateral arm extending toward a joint, the lateral arm being sloped in the direction of the joint and being adapted to receive a joint ball. The lateral arm has significantly greater length in a region adjacent the shaft and measured therealong than its corresponding thickness. A second member can be pushed onto the shaft portion supporting the lateral arm. This second member receives a distal end of the first member, with the second member essentially completely receiving the shaft portion supporting the lateral arm. The first member is joined at its proximal end to a proximal end of the second member. The lateral arm extends through a slit portion in the second member such that the region of the lateral arm adjacent the shaft portion is disposed within the slit portion.
