This study aimed to evaluate the outcome of medial open reduction for developmental dysplasia of the hip (DDH) in patients before and after walking age. A minimum 5-year radiographic and clinical follow-up compared 29 patients (group 1) before walking age with 38 patients (group 2) after walking age for DDH. The correction ratio of acetabular index was similar in both groups postoperatively (41.8% for group 1 and 44.9% for group 2), and it was statistically not significant (P>0.05). The Kalamchi-MacEwen classification showed no correlation between operative age and the rate of avascular necrosis (P>0.05). This report presents similar complication rates as that of the Severin criteria for medial open reduction of the hip and challenges the conventional belief that a medial open reduction for the treatment of DDH in a walking-age child at short-term to mid-term follow-up has comparable results.
本研究旨在评估髋关节发育不良（DDH）患者在开始行走前后接受内侧切开复位术的疗效。对29例开始行走前的患者（第1组）和38例开始行走后的DDH患者进行了至少5年的影像学和临床随访。两组术后髋臼指数的矫正率相似（第1组为41.8%，第2组为44.9%），且差异无统计学意义（P>0.05）。Kalamchi-MacEwen分类显示手术年龄与无血管性坏死发生率之间无相关性（P>0.05）。本报告显示内侧切开复位术的并发症发生率与Severin标准相似，并且对传统观念提出了挑战，即对于行走年龄儿童的DDH，在短期至中期随访中进行内侧切开复位术可获得相当的效果。
