We compared the results of the metal-on-metal hip resurfacing with the ceramic-on-ceramic total hip arthroplasty (THA) in 2 groups. The preoperative and postoperative ranges of motion (ROMs) were recorded. At the latest follow-up, both of the groups make satisfactory clinical and radiographic results. There was no significant difference in Harris hip score of the 2 groups, but the ROM of the hips in hip resurfacing group was significantly wider than THA group (P < .01). Hip resurfacing has better ROM improvement than THA, with the same pain relief. Its high stability and low dislocation rate allow patients to do early function exercises, which is important for ankylosing spondylitis (AS) patients to avoid reankylosis. Hip resurfacing may be a reasonable option for young AS population.
我们比较了两组金属对金属髋关节表面置换与陶瓷对陶瓷全髋关节置换（THA）的结果。记录了术前和术后的活动范围（ROM）。在最新的随访中，两组均获得了满意的临床和影像学结果。两组的 Harris 髋关节评分无显著差异，但髋关节表面置换组的髋关节 ROM 明显大于 THA 组（P<.01）。髋关节表面置换术比 THA 具有更好的 ROM 改善效果，同时也能缓解疼痛。其高稳定性和低脱位率使患者能够进行早期功能锻炼，这对于强直性脊柱炎（AS）患者避免再融合非常重要。髋关节表面置换术可能是年轻 AS 人群的合理选择。
