Supraspinatus tendon attrition before and after implants removal. Sonographic findings of a 40-year-old man who had shoulder impingement syndrome before implant removal. (A) A partial thickness tear was noted at the bursal aspect of the supraspinatus tendon (SSP), which resulted from repetitive mechanical attrition by the hook of the plate (arrow). The infraspinatus tendon (ISP) was intact. (B) 1 month after implant removal, the same patient was re-evaluated. Musculoskeletal sonography showed the dimpling lesion had become less obvious than before.
