Abstract

Short-stemmed hip implants were established in total hip arthroplasty in the last years. Also patients with secondary osteoarthritis of the hip with pathological anteversion of the femoral neck are treated increasingly using this method. Therefore an investigation was performed to analyze the resulting hip contact force and femoral loading in the proximal femur at the solid model of the “standardized femur”. Two different situations of femoral component anteversion were simulated. Increased hip contact forces and an increase of medial and lateral cortex loads result in the anteverted model. With present level of knowledge about the influence of the hip contact force the use of short-stemmed implants is not uncritically in patients with degenerative osteoarthritis of the hip combined with rotational disorders of the proximal femur. The selection of the tribological pairing is to be considered more strongly regarding the wear behavior.
