Although myositis ossificans is a well-known sequela of elbow trauma, reinjury to the affected region can also occur, resulting in acute symptoms from a fracture of the myositis ossificans. An 18-year-old man presented with localized pain, soft-tissue swelling, and a bony mass along the anterolateral distal humerus with restricted elbow range of motion after injury to his elbow during football. One year earlier he had sustained a similar crush injury to his elbow that resulted in a limited, although painless, arc of motion. Radiographs and tomograms established the diagnosis of a fractured supracondylar humeral myositis ossificans. Surgical excision of the large mature ossified fragment confirmed the diagnosis and restored a full range of motion of the elbow.
尽管骨化性肌炎是肘部创伤的一种常见后遗症，但受影响区域也可能再次受伤，导致骨化性肌炎骨折引起急性症状。一名18岁男性在踢足球时肘部受伤后，出现局部疼痛、软组织肿胀以及肱骨远端前外侧有一骨块，且肘关节活动范围受限。一年前他的肘部曾遭受类似的挤压伤，导致活动弧度有限但无痛。X线片和断层扫描确诊为肱骨髁上骨化性肌炎骨折。手术切除大的成熟骨化碎片证实了诊断，并恢复了肘关节的全范围活动。
