The aim of this study was to compare return to sport activity between a short femoral cementless stem and a conventional femoral cementless stem in total hip arthroplasty in patients 50 years old and younger.
We retrospectively reviewed 55 patients (61 hips) treated with a short femoral cementless stem and 28 patients (32 hips) treated with a conventional femoral cementless stem 50 years old and younger from December 2009 and December 2014.Their mean age was 39.86 (22-49) years and 38.68 (18-49) years, respectively. The mean follow-up was 54.1 (15-68) months and 52.7 (15-72) months, respectively. They were pre- and postoperatively evaluated by the clinical and radiological examination.
No patients with the short stem had intraoperative fracture, but 1 patient with the conventional stem had intraoperative fracture. At final follow-up, there was no statistically significant difference in Harris Hip Score, and radiographic review level between 2 stems. No hip with the short stem had thigh pain, but 6 hips with the conventional stem had thigh pain at the final follow-up. No component was revised for aseptic loosening in either group. There were no differences observed in the return to sports activity between the 2 groups.
Our study demonstrated that both short cementless stem and conventional cementless stem provided stable fixation and achieved a satisfactory result in patients 50 years old and younger. There is no difference in return to sports activity level after the procedure.
本研究的目的是比较在50岁及以下患者的全髋关节置换术中，短柄非骨水泥型股骨柄与传统非骨水泥型股骨柄在恢复体育活动方面的差异。
我们回顾性分析了2009年12月至2014年12月期间接受短柄非骨水泥型股骨柄治疗的55例患者（61髋）和接受传统非骨水泥型股骨柄治疗的28例患者（32髋），年龄均在50岁及以下。他们的平均年龄分别为39.86岁（22 - 49岁）和38.68岁（18 - 49岁）。平均随访时间分别为54.1个月（15 - 68个月）和52.7个月（15 - 72个月）。通过临床和影像学检查对他们进行术前和术后评估。
使用短柄的患者术中均未发生骨折，但使用传统柄的1例患者术中发生骨折。在末次随访时，两组间Harris髋关节评分及影像学评估水平无统计学显著差异。使用短柄的患者中没有出现大腿疼痛，但在末次随访时，使用传统柄的有6髋出现大腿疼痛。两组均无因无菌性松动而进行翻修的病例。两组在恢复体育活动方面未观察到差异。
我们的研究表明，短柄非骨水泥型股骨柄和传统非骨水泥型股骨柄在50岁及以下患者中均能提供稳定的固定，并取得了满意的结果。术后恢复体育活动的水平没有差异。
