Development of a new femoral implant for revision hip arthroplastty

The fixation of the cementless femoral implants used in revision total hip arthroplasty is mostly obtained in the distal part. Since in this region the medullar canal geometry is close to a circular cylinder, the implants should show some features in order to prevent rotation and subsidence under physiological loads. This paper proposes a new design for a modular femoral implant that includes a part with longitudinal splines and a threaded part. A finite element analysis estimates the stress in bone and relative micromotion.
