For periacetabular osteotomy, traditional approaches usually have a long learning curve. We aimed to evaluate the postoperative results and complications of periacetabular osteotomy under a new double-incision approach.
The records of 58 consecutive patients (65 hips) who underwent periacetabular osteotomy using the new approach were retrospectively reviewed and evaluated. There were 52 women and 6 men with a mean age of 28.1 years at the time of surgery.
The average follow-up period was 35.2 months, during which no patients were converted to total hip arthroplasty. Complications included 6 hips (9.2%) with nerve dysesthesias and 1 hip (1.5%) with delayed wound healing. The mean operative time and intraoperative blood loss were 88.6 min and 402.8 ml, respectively. The mean modified Harris hip score had improved from 72.2 points preoperatively to 91.3 points at the last follow-up. Fifty-five patients (62 hips, 95.4%) were satisfied to their outcomes, and good preoperative functional score was associated with a satisfactory outcome. Furthermore, the average lateral center-edge angle, anterior center-edge angle and acetabular index angle were corrected well after surgery.
Periacetabular osteotomy using modified Smith-Petersen or Bikini approach with posterolateral assisted small incision can be performed safely and with satisfactory results. In addition, this technique shortens the learning curve, and reduces the operating complexity, especially for beginner.
对于髋臼周围截骨术，传统方法通常具有较长的学习曲线。我们旨在评估新双切口入路下髋臼周围截骨术的术后结果和并发症。
回顾性分析了 58 例（65 髋）采用新入路行髋臼周围截骨术患者的临床资料。其中女性 52 例，男性 6 例，平均年龄 28.1 岁。
平均随访 35.2 个月，无患者转为全髋关节置换术。并发症包括 6 髋（9.2%）神经感觉异常和 1 髋（1.5%）切口愈合延迟。平均手术时间和术中出血量分别为 88.6 分钟和 402.8 毫升。改良 Harris 髋关节评分由术前的 72.2 分提高至末次随访时的 91.3 分。55 例（62 髋，95.4%）患者对疗效满意，术前功能评分良好与满意的疗效相关。此外，术后平均外侧中心边缘角、前中心边缘角和髋臼指数角得到良好矫正。
改良 Smith-Petersen 或 Bikini 入路结合后外侧辅助小切口行髋臼周围截骨术安全有效，可缩短学习曲线，降低手术难度，尤其适用于初学者。
