Abstract:
Total hip arthroplasty has become one of the most succesful procedure in orthopaedic surgery. More and more active, young patients undergo primary hip replacement. Bone stock preservation is crucial when performing THR in this group of patients. The short stem design allows a methaphyseal intratrochanteric multipoint, strong primary fixation which is very important for this group of patients. The goal is to save bone stock for the revision operation. This study presents early results of Metha short stems prosthesis. Between April 2006-December 2007, 58 short stem (Metha) were implanted. The Harris Hip Score improved from a mean 64.3 before to 89.7 at follow-up. The Metha stem may not be indicated for every hip diseases. There were only two fractures of femur without any further problems. Despite the short follow-up, Metha prosthesis already represent a valuable alternative for younger patients.
