Developmental dysplasia of the hip (DDH) encompasses abnormalities in the acetabulum or the femoral head, ranging from mild dysplasia to complete dislocation. The primary goal of DDH treatment is to achieve and maintain a concentric reduction of the hip joint, allowing for normal acetabular and femoral head remodeling.
This retrospective study reviewed records of patients treated for idiopathic DDH between 2016 and 2021 at a single institution. Patients included had undergone either closed or open reduction and completed at least two years of follow-up. Demographic data and radiographic assessments at multiple intervals postreduction were collected and analyzed using IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York, United States).
A total of 41 patients (64 hips) were included, with a mean age at reduction of 6.92 months and a follow-up duration of 51.5 months. Closed reduction was performed on 38 hips, while 26 hips underwent open reduction. The mean age at reduction was significantly lower in the closed reduction group (4.58 months) compared to the open reduction group (10.34 months). The mean preoperative acetabular index (AI) decreased from 37.39 to 19.54 in the closed reduction group and from 36.74 to 19.4 in the open reduction group.
The study found no significant difference between closed and open reduction techniques in acetabular remodeling. While residual dysplasia and avascular necrosis (AVN) were more common in the closed group, the differences were not statistically significant. Further research with larger sample sizes and longer follow-up periods is recommended to confirm these findings.
发育性髋关节发育不良（DDH）包括髋臼或股骨头的异常，范围从轻度发育不良到完全脱位。DDH治疗的主要目标是实现并维持髋关节的同心复位，以允许髋臼和股骨头正常重塑。
这项回顾性研究回顾了2016年至2021年在单一机构接受特发性DDH治疗的患者记录。纳入的患者接受了闭合或开放复位，并完成了至少两年的随访。收集了复位后多个时间点的人口统计学数据和影像学评估，并使用IBM SPSS Statistics for Windows 29版（2023年发布；IBM公司，美国纽约州阿蒙克）进行分析。
共纳入41例患者（64髋），复位时平均年龄为6.92个月，随访时间为51.5个月。38髋进行了闭合复位，26髋进行了开放复位。与开放复位组（10.34个月）相比，闭合复位组复位时的平均年龄显著更低（4.58个月）。闭合复位组术前平均髋臼指数（AI）从37.39降至19.54，开放复位组从36.74降至19.4。
该研究发现闭合复位和开放复位技术在髋臼重塑方面无显著差异。虽然闭合组残余发育不良和缺血性坏死（AVN）更常见，但差异无统计学意义。建议进行更大样本量和更长随访期的进一步研究以证实这些发现。
