评估动态长腿铸造对髋关节发育不良（DDH）诊断为12-18个月的髋关节发育不良（DDH）的影响。
根据TONNIS放射线学脱位分类，采用了加法术，闭合的减少和动态的长腿铸造方法。功能标准和Severin的放射学标准。
共有246名患者（339个臀部）在固定3个月后具有完整的随访数据，结果在264个臀部（77.88％）中得到满足。 43（79.07％）4型臀部的基线AI越高在339（78.47）的266个臀部中，发现了“出色”和“良好”臀部功能。
动态长腿铸造是一种治疗DDH患者在诊断时为12-18个月的患者的有效方法。
To evaluate the effect of dynamic long leg casting in paediatric patients with developmental dysplasia of hip (DDH) diagnosed at 12–18 months. The adductor tenotomy, closed reduction, and dynamic long leg casting method was adopted to treat paediatric patients with DDH. The hips were divided into four groups according to the Tonnis radiographic dislocation classification. Groups were also classified according to the baseline acetabular index (AI): 30°–35°, 36°–40°, and > 40°. The outcomes of the reductions were evaluated according to McKay’s hip function criteria and Severin’s radiological criteria. A total of 246 patients (339 hips) had complete follow-up data. After 3 months of orthosis fixation, the results were satisfactory in 264 hips (77.88%). Hip function was rated as ‘excellent’ or ‘good’ in 43 of 51 (84.31%) Tonnis type 1 hips, 125 of 155 (80.65%) type 2 hips, 70 of 90 (77.78%) type 3 hips, and 34 of 43 (79.07%) type 4 hips. The higher the baseline AI, the lower the rates of ‘excellent’ and ‘good’ hip function. Favourable radiological results (Severin types I and II) were found in 266 of 339 (78.47) hips. Dynamic long leg casting is an effective method for treating patients with DDH aged 12–18 months at diagnosis.
