The best treatment for a fractured neck of femur in an old person is considered by many to be replacement hemiarthroplasty which allows the patient to walk immediately on a stable, painless hip. The late results can be marred by acetabular erosion in which the metal head of the prosthesis erodes upwards into the acetabulum to give pain and disability. Here the trial of a new bipolar prosthesis with a dynamic self-aligning outer head is described in 161 fractured necks of femur. No acetabular erosion has been seen with its use over four years.
许多人认为，老年股骨颈骨折的最佳治疗方法是半髋关节置换术，该方法可使患者立即在稳定、无痛的髋关节上行走。后期结果可能会因髋臼磨损而受到影响，在这种情况下，假体的金属头向上侵蚀髋臼，导致疼痛和残疾。本文描述了对161例股骨颈骨折患者使用新型动态自对准外股骨头双极假体的试验情况。在四年多的使用过程中，未发现髋臼磨损情况。
