Heterotopic ossification (HO) is the abnormal growth of extraskeletal bone. Joint involvement may result in chronic stiffness and pain causing considerable functional impairment and the inability to perform the activities of daily living. HO affecting the shoulder joint is rare and little is known about its clinical course or treatment. Here, we describe the first reported case of glenohumeral HO following anterior dislocation. This occurred in a 70-year-old man following a fall onto outstretched hand. Due to persistent stiffness and pain at 8 months from initial injury, he underwent plain radiographs and MRI scans that confirmed rotator cuff tear and HO. He was managed conservatively with physiotherapy and non-steroidal anti-inflammatory drugs. At 1-year follow-up, the patient maintains a good functional outcome.
异位骨化（HO）是骨骼外异常的骨生长。关节受累可能导致慢性僵硬和疼痛，造成相当大的功能损害以及无法进行日常生活活动。影响肩关节的HO很少见，对其临床病程或治疗了解甚少。在此，我们描述首例报告的前脱位后肱盂关节HO病例。这发生在一名70岁男性因伸手跌倒之后。在初始损伤8个月时，由于持续的僵硬和疼痛，他接受了X线平片和MRI扫描，证实存在肩袖撕裂和HO。他接受了物理治疗和非甾体抗炎药的保守治疗。在1年随访时，患者保持了良好的功能结果。
