骨化性肌炎是肌肉发生严重挫伤所致的一种良性疾病,由于肌纤维、结缔组织、血管和骨膜对损伤的反应而发生异养的骨形成。这过程中可导致患者长期病发。据认为损害较小者以及发生于上肢者较有可能完全吸收,而大的损害以及发生于靠近肌肉起止点者较可能持续存在。骨化性肌炎最常见于15～30岁男子。此病可发生于多个解剖部位,但仅常见于大腿前部,文献中甚少报道发生于上臂者。 Osteogenetic myositis is a benign condition caused by severe contusion of the muscle and heterotrophic bone formation occurs due to the damage of muscle fibers, connective tissue, blood vessels and periosteum. This process can lead to long-term disease in patients. It is believed that less damaging and those occurring in the upper extremities are more likely to be fully absorbed, while greater damage and those that occur near the start and end of the muscle are more likely to persist. Osteomyelitis is most common in men aged 15 to 30 years. The disease can occur in multiple anatomical sites, but only in the anterior thigh, rarely reported in the literature in the upper arm.
