Ilio-psoas impingement after total hip arthroplasty often occurs with the metallic rim of the acetabular cup. The main causes are poor cup anteversion or anterior wall defect. We firstly report here the case of a patient complaining of iliopsoas impingement due to contact with the liner of a dual-mobility device. Ultrasonography and Computed Tomographic scan clearly showed the direct mechanical contact of the dual-mobility liner with the iliopsoas tendon.
全髋关节置换术后髂腰肌撞击常发生于髋臼杯的金属边缘。主要原因是髋臼杯前倾角不当或前壁缺损。我们在此首次报告一例患者因与双动装置的内衬接触而出现髂腰肌撞击的病例。超声检查和计算机断层扫描清楚地显示了双动内衬与髂腰肌肌腱的直接机械接触。
