Even small changes in local bone mass that are not visible with conventional radiographs can be detected using dual xray absorptiometry. Commonly there is a loss of 10% to 45% of the periprosthetic bone mass during the first years after total hip arthroplasty. Recent studies have suggested that this bone loss is not necessarily progressive and some degree of restoration of bone density around implants may occur. Current data suggest that there is active bone remodeling in the proximal femur in response to prosthetic implantation. Such response differs between different stem designs and type of fixation.
