摘　　要：臀肌挛缩症(gluteal muscle contracture,GMC)中国发病率较欧美偏高,尤其是儿童患病率较高,约为1.0%~2.5%[1]。由于会影响儿童骨盆发育,是造成儿童残疾的重要原因之一。随着年龄增长,GMC的临床症状和体征逐渐加重,同时骨盆倾斜和脊柱侧弯等并发症的发生率也增加。因此,早期准确诊断对于指导临床治疗至关重要。临床主要通过体征和病史进行诊断,超声、MRI等检查方式可评估病情。治疗主要是开放性手术,切除挛缩带恢复肌腱弹性。报告本病例旨在通过超声检查分析GMC,为临床提供新思路和理论依据。Objective To report the ultrasound imaging findings of a patient with gluteal muscle contracture.Methods We retrospectively analyzed the clinical and imaging findings of a patient with gluteal muscle contracture treated at our hospital.Results The main symptoms of gluteal muscle contracture were abnormal gait and posture.The clinical signs were evident,and the patient’s medical history was clear.Ultrasound imaging revealed abnormal hyperechoic fibrous bands within the gluteus medius muscle,with disrupted muscle fibers forming a mass-like appearance.The surrounding fascia was thickened,and dynamic observation revealed rigid tendons and unsmooth movements.By localization,it was determined that the lesion in this case was confined to the gluteus medius muscle.Conclusions Ultrasound examination is specific for the diagnosis of gluteal muscle contracture.In clinical practice,there may be situations where the lesion localization is unclear.Ultrasound examination can help accurately locate and assess the extent of involvement,thereby assist in the clinical diagnosis and treatment.
