目的:探讨臀肌挛缩症致骨盆、髋关节方面变化,阐明手术时机和效果。方法:比较38例臀肌挛缩症与30例非臀肌挛缩症骨盆、髋关节平片,38例臀肌挛缩症中,20例术后6～7年随访。结果:臀肌挛缩症患儿的 CE 角增大(X=36.32°,P<0.01),颈干角增大(X=153°,P<0.01),股骨头指数下降(X=0.44,P<0.01)。20例臀肌挛缩症术后6～7年随访,CE 角(X=35°)颈干角(X=134.95°)肌骨头指数(X=0.489)均恢复同龄组正常均值内。结论:臀肌挛缩症可引起骨盆、髋关节继发性改变,手术有助于髋关节形态和功能恢复。
Objective: To investigate the changes of pelvic and hip joint caused by gluteal muscle contracture and to clarify the timing and effect of operation. Methods: 38 cases of gluteal muscle contracture and 30 cases of non-gluteal muscle contracture pelvis, hip plain film, 38 cases of gluteal muscle contracture, 20 cases were followed up for 6 to 7 years. Results: The CE angle of gluteal muscle contracture increased (X = 36.32 °, P <0.01), the neck angle increased (X = 153 °, P <0.01) and the femoral head index decreased <0.01). Twenty patients with gluteal contracture at 6-7 years postoperative follow-up were observed. The BCI (X = 34.95 °) and CEA (X = Conclusion: Gluteal muscle contracture can cause secondary changes of the pelvis and hip joint. The operation contributes to the shape and function recovery of the hip joint.
