Twenty-eight children were treated who had limited flexion of the hips and various degrees of contracture of the abductor and external rotator muscles because of fibrosis of the gluteus maximus muscle. Although the lesions could be classified as those associated with poliomyelitis, infection of the gluteus maximus muscle, and fibrosis of unknown etiology, all forty-five hips had a typical restriction of motion such that an affected hip could not be flexed in the usual sagittal plane, but had to be flexed in abduction. Poliomyelitis may have been adjunctive to the causative factor of the lesion in some cases but the probable primary etiology was multiple intramuscular injections. Excellent correction of the hip contracture was achieved in all patients by division of the fibrotic bands.
28名儿童因臀大肌纤维化而出现髋关节屈曲受限以及外展肌和外旋肌不同程度的挛缩，接受了治疗。尽管这些病变可归类为与小儿麻痹症、臀大肌感染以及病因不明的纤维化相关，但所有45个髋关节均有典型的活动受限，即患侧髋关节无法在通常的矢状面内屈曲，而必须在外展位屈曲。在某些病例中，小儿麻痹症可能是病变致病因素的辅助因素，但可能的主要病因是多次肌肉注射。通过切断纤维化带，所有患者的髋关节挛缩均得到了良好矫正。
