CASE
A 64-year-old woman developed worsening sciatica associated with snapping at the hip over a period of 4 years. The physical examination and dynamic ultrasound revealed the snapping of the sciatic nerve (SN) provoked by impingement between the greater trochanter (GT) and the ischium. Additional imaging studies demonstrated hyperintense signal in the SN at the hip, sagittal imbalance, decreased ischiofemoral space, and increased femoral torsion.
CONCLUSION
Snapping and entrapment of the SN provoked by impingement between the GT and the ischium should be considered in the differential diagnosis of snapping hip and/or sciatica.
病例
一位 64 岁女性出现进行性加重的坐骨神经痛，伴髋关节弹响，病史 4 年。体格检查和动态超声显示坐骨神经（SN）在大转子（GT）和坐骨之间受到撞击时出现弹响。其他影像学研究显示髋关节处 SN 信号增高、矢状位失平衡、坐骨股骨间隙减小和股骨扭转增加。
结论
应考虑 GT 和坐骨之间撞击引起的 SN 弹响和/或卡压在弹响髋和/或坐骨神经痛的鉴别诊断中。
