臀小肌该肌位于臀中肌深面，其形态、起止、功能及血管神经分布都与臀中肌相同，故可将此肌视为臀中肌的一部分。
结果84例臀肌挛缩症合并骨盆倾斜患者，假性长肢侧臀小肌挛缩者76例，占90％。
Results Among the 84 cases of gluteal contracture with the pelvis obliquity, 76(90% ) cases had gluteal muscle contracture of the longer limp.
结论单侧臀肌挛缩症伴骨盆倾斜，多由臀中肌、臀小肌挛缩带引起髋关节外展畸形导致负重力线的改变而致病。
Conclusion gluteus medius and gluteus minimus could result in coxae abduction malformation and alteration of weight line, leading to pelvic obliquity.
