Abstract:

The use of large-diameter femoral heads in total hip arthroplasty appears to reduce the risk for dislocation, and potentially improve articular wear. Moreover, large-diameter total hip femoral heads have been determined to increase range of motion. The purpose of this study was to report our experiences with this new device. In our patient cohort, many patients have done extremely well in the short-term with this new device, and it seems these patients function better than those with a standard total hip arthroplasty. The patients who experience less pain are able to return to full activities postoperatively. The preliminary results of this study are encouraging, and large femoral head prosthesis appears to be a great choice for orthopaedic surgeons in primary total hip arthroplasty.
