We measured bone mineral density (BMD) in the proximal femur by dual-energy X-ray absorptiometry (DEXA) 20 patients after cemented total hip arthroplasty over a period of one year. found statistically significant reduction periprosthetic BMD six months on medial side and lateral adjacent to mid distal thirds prosthesis. At year operation there was mean 6.7% region calcar 5.3% increase femoral shaft tip implant. These changes reflect pattern reduced stress increased around They support current concepts remodelling response prosthetic implantation.
