Gluteal muscle contracture (GMC) is a clinical syndrome characterized by limited hip joint function due to fibrosis and contracture of the gluteal muscle and fascia fiber. Imaging examination is significant for its diagnosis and guidance of surgical treatment.
This report presents 3 cases of GMC with bilateral involvement and summarizes the literature on the imaging findings of this disease. The clinical symptoms and presentations of the 3 cases well-matched the clinical diagnosis of GMC. Preoperative ultrasonography including elastography was performed. To our knowledge, studies based on the elastography findings of the disease are limited.
The diagnosis of GMC was finally confirmed by postoperative pathologic examination.
All 3 patients then have a surgical therapy which cut off the contracture tract.
Symptoms of abnormal gait and limited hip joint function were greatly improved after surgical treatment.
The elasticity of the GMC zone in patients with GMC is higher than that of the muscles in the corresponding sites of healthy people.
臀肌挛缩症（GMC）是一种临床综合征，其特征是由于臀肌和筋膜纤维的纤维化和挛缩导致髋关节功能受限。影像学检查对其诊断及手术治疗指导具有重要意义。
本报告呈现了3例双侧受累的臀肌挛缩症病例，并总结了关于该疾病影像学表现的文献。这3例患者的临床症状和表现与臀肌挛缩症的临床诊断高度相符。术前进行了包括弹性成像在内的超声检查。据我们所知，基于该疾病弹性成像结果的研究有限。
臀肌挛缩症的诊断最终通过术后病理检查得以证实。
所有3例患者均接受了切断挛缩条索的手术治疗。
手术治疗后，异常步态和髋关节功能受限的症状得到了显著改善。
臀肌挛缩症患者的臀肌挛缩区域弹性高于健康人相应部位的肌肉。
