[Early functional results with the Mayo-hip, a short stem system with metaphyseal-intertrochanteric fixation].

Total hip arthroplasty has become one of the most successful standard procedures in orthopedic surgery. With a more frequent use in young and active patients bone saving procedures become more important. The goal is to save good bone stock for the revision procedure. One example of conservative femoral implants is the Mayo-stem with reported long term results. The stem design allows a metaphyseal intertrochanteric multipoint fixation for primary fixation. The surgical technique is simple. Using a transgluteal approach, the medial preparation of the femoral neck decreases significantly the irritation of the abductor tendons. In a prospective-randomized study, the early functional results with the Mayo-stem were significantly better than the results achieved with a cement-free standard stem. The Mayo-stem may not be indicated for every hip situation. Its use, however, in cases with normal anatomy contributes to save autologeous bone. Therefore, this short stem is a sensible alternative to standard stems.
