Biomechanic conception of implant choice for primary total hip replacement in osteoporotic femur neck fractures is presented. Criterion for the choice is a localization of load-bearing surface of dense structure in acetabulum roof zone, i.e. sursile. Absolute indications to total hip replacement, use of bipolar and unipolar hemiprostheses are determined depending on the direction and deviation degree of sursile from horizontal axis of pelvis. Based on suggested conception the retrospective analysis of joint replacement results in 58 patients has been performed. The causes of protrusion and loosing of implants were studied.
