Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO ). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.
异位骨化是指在非典型的骨骼外组织中形成骨组织，通常自发发生或继发于原因不明的神经损伤后。我们报告一例46岁女性，右肩疼痛伴活动范围（ROM）受限3个月，无外伤史。磁共振成像（MRI）显示肩胛上盂旋转袖内有一病变。先前机构的切除活检显示为骨化性肌炎（HO）。经重复MRI和骨扫描后，关节镜切除的组织病理学检查证实为HO。患者在随访时疼痛减轻，ROM改善。特发性HO很少发生于肩关节，HO切除应推迟至病变成熟以避免复发。本例表明，关节镜下HO切除术可提供良好的手术视野，以确保完全切除病变，并使肩胛上盂区域的软组织损伤最小化。此外，关节镜的微创手术可能会缩短康复时间并促进早日重返工作岗位。
