140 patients scheduled for total hip arthroplasty were randomized to receive either a short femoral stem tor conventional-length straight femoral stem. The primary interest of this study was change in periprosthetic bone mineral density, and whether BMD loss was significantly smaller in the short stem group. Patients were assessed over 5-year follow-up. Results demonstrated significantly smaller c...
