Patients with cerebral palsy and fixed hip extension are often unable to sit and therefore lose social and educational opportunities. At Texas Scottish Rite Hospital (Dallas, TX, U.S.A.), 29 patients had hip extension-abduction contractures. Eleven patients with mild involvement were managed with physical therapy. Six patients had moderate involvement and required wheelchair modification to maintain sitting. Twelve patients demonstrated severe contractures that required major soft tissue releases and often femoral shortening osteotomies to regain flexion. Patients with athetosis or rigidity were identified as those most likely to develop extension-abduction contractures either spontaneously or following adductor releases.
患有脑瘫且髋关节固定性伸展的患者往往无法坐立，从而失去社交和教育机会。在美国得克萨斯州达拉斯市的德克萨斯苏格兰 rite 医院，29 例患者存在髋关节伸展 - 外展挛缩。11 例轻度受累患者接受了物理治疗。6 例中度受累患者需要对轮椅进行改装以维持坐姿。12 例患者表现出严重挛缩，需要进行大面积软组织松解，且常常需要进行股骨缩短截骨术以恢复屈曲。患有手足徐动症或强直的患者被确定为最有可能自发或在内收肌松解后发生伸展 - 外展挛缩的人群。
