The aim of this study was to assess whether a femoral component which retained the neck reduced the incidence of leg-length inequality following total hip arthroplasty. A retrospective review was undertaken of 130 consecutive primary total hip arthroplasties performed between April 1996 and April 2004 using such an implant. There were 102 suitable patients for the study. Standardised pre- and post-operative pelvic radiographs were measured by an independent investigator to the nearest millimetre. The leg-length inequality was reduced from a mean pre-operative value of -0.71 cm to a mean of 0.11 cm post-operatively. Of the 102 patients 24 (23.5%) had an equal leg-length post-operatively, and 95 (93.1%) had a leg-length inequality between -1 cm and 1 cm.
本研究的目的是评估保留股骨颈的股骨假体是否能降低全髋关节置换术后肢体长度不等的发生率。对1996年4月至2004年4月间连续进行的130例使用此类植入物的初次全髋关节置换术进行了回顾性研究。有102例适合该研究的患者。由一名独立研究者对标准化的术前和术后骨盆X线片进行测量，精确到毫米。肢体长度不等从术前平均-0.71 cm降至术后平均0.11 cm。在这102例患者中，24例（23.5%）术后肢体长度相等，95例（93.1%）肢体长度不等在-1 cm至1 cm之间。
