AIMS Developmental dysplasia of the hip (DDH) describes a pathological relationship between the femoral head and acetabulum. Periacetabular osteotomy (PAO) may be used to treat this condition. The aim of this study was to evaluate the results of PAO in adolescents and adults with persistent DDH. METHODS Patients were divided into four groups: A, adolescents who had not undergone surgery for DDH in childhood (25 hips); B, adolescents who had undergone surgery for DDH in childhood (20 hips); C, adults with DDH who had not undergone previous surgery (80 hips); and D, a control group of patients with healthy hips (70 hips). The radiological evaluation of digital anteroposterior views of hips included the Wiberg angle (centre-edge angle (CEA)), femoral head cover (FHC), medialization, distalization, and the ilioischial angle. Clinical assessment involved the Harris Hip Score (HHS) and gluteal muscle performance assessment. RESULTS Significant improvements in radiological parameters were achieved in all measurements in all groups (p < 0.05). The greatest improvement was in CEA (mean of 19° (17.2° to 22.3°) in Group B), medialization (mean of 3 mm (0.9 to 5.2) in Group C), distalization (mean of 6 mm (3.5 to 8.2) in Group B), FHC (mean of 17% (12.7% to 21.2%) in Group B), and ilioischial angle (mean of 5° (2.3° to 8.1°) in Group B). There were significant improvements in the mean HHS and gluteal muscle performance scores postoperatively in all three groups. CONCLUSION The greatest correction of radiological parameters and clinical outcomes was found in patients who had undergone hip surgery in childhood. Although the surgical treatment of DDH in childhood makes subsequent hip surgery more difficult due to scarring, adhesions, and altered anatomy, it requires less correction of the deformity and has a beneficial effect on the outcome of PAO in adolescence and early adulthood.

青春期髋关节发育不良：儿童截骨术改善了青少年和年轻人髋臼周围截骨术的结果：一项前瞻性研究。

AIMS 发育性髋关节发育不良 (DDH) 描述了股骨头和髋臼之间的病理关系。髋臼周围截骨术 (PAO) 可用于治疗这种情况。本研究的目的是评估 PAO 在患有持续性 DDH 的青少年和成人中的结果。方法将患者分为四组：A、儿童期未接受过DDH手术的青少年（25髋）；B、儿童期接受过DDH手术的青少年（20髋）；C，既往未接受过手术的 DDH 成人（80 髋）；D，健康髋关节患者的对照组（70髋）。髋关节数字前后位的放射学评估包括 Wiberg 角（中心边缘角（CEA））、股骨头覆盖（FHC）、内侧、远端和髂坐角。临床评估涉及哈里斯髋关节评分 (HHS) 和臀肌性能评估。结果 在所有组的所有测量中均实现了放射学参数的显着改善（p < 0.05）。最大改善是 CEA（B 组平均 19°（17.2° 至 22.3°））、内侧化（C 组平均 3 mm（0.9 至 5.2））、远端化（平均 6 mm（3.5 至 8.2） B 组）、FHC（B 组平均 17%（12.7% 至 21.2%））和髂坐角（B 组平均 5°（2.3° 至 8.1°））。三组术后平均 HHS 和臀肌功能评分均有显着改善。结论 在儿童期接受过髋关节手术的患者中发现放射学参数和临床结果的最大矫正。虽然由于瘢痕、粘连和解剖结构改变，儿童期 DDH 的手术治疗使随后的髋关节手术更加困难，但它需要较少的畸形矫正，并且对青春期和成年早期 PAO 的结果具有有益影响。引用这篇文章：骨关节 J 2022;104-B(7):775-780。
