This study investigates retrospectively the preoperative findings and postoperative courses of 580 children with altogether 1001 intertrochanteric osteotomies. The evaluation of on average 5 postoperative years determines criteria assisting the revalgisation of the femoral neck. Of main importance is the age at the date of operation; the younger the child is the higher is the degree of revalgisation. An also important factor is the preoperative CCD-angle, high values correlate with a high revalgisation rate. Exceptional features and alterations of femoral head, form and depth of the hip-socket also assist the revalgisation of femoral neck. Mechanical mistakes, little varization, low medialization of distal femoral fragment e.g., lead to an increase of postoperative CCD-angle; meanwhile damage of the apophyseal or epiphysial line does not affect the revalgisation.
本研究回顾性调查了580例患儿共1001次转子间截骨术的术前检查结果及术后病程。平均5年的术后评估确定了有助于股骨颈再 valgisation（可能有误，原文似拼写错误，暂按此翻译）的标准。手术时的年龄至关重要；患儿年龄越小，再 valgisation程度越高。术前颈干角（CCD角）也是一个重要因素，高值与高再valgisation率相关。股骨头的特殊特征和改变、髋臼的形态和深度也有助于股骨颈的再valgisation。机械性错误，如股骨远端碎片的小内翻、低内移等，会导致术后CCD角增加；同时，骨骺或骺板损伤并不影响再valgisation。
