Myositis ossificans is a benign condition resulting from severe muscular contusion manifested by heterotrophic bone formation. The process is common in the anterior thigh but the literature dealing with myositis ossificans in the upper arm is limited. Ten cases of the condition in the upper arm were seen in our practice. All 10 were the result of football injuries and exhibited one or more of the triad of local pain, a hard palpable mass in the muscle, and a flexion contracture of the elbow. Seven of the cases (70%) were asymptomatic or signficantly improved in less than 3 months with conservative nonoperative management. Three patients (30%) underwent surgery because the painful mass persisted. In two (66%) of the surgically managed cases, there was clinical and radiographic evidence of recurrence postoperatively in spite of delaying excision until radiographic parameters of maturation were present.
骨化性肌炎是一种由严重肌肉挫伤导致的良性疾病，表现为异位骨形成。该过程在前臂较为常见，但关于上臂骨化性肌炎的文献有限。我们在临床实践中遇到了10例上臂骨化性肌炎病例。所有10例均因足球运动损伤所致，表现出局部疼痛、肌肉内可触及硬块和肘部屈曲挛缩三联征中的一项或多项。7例（70%）患者经保守非手术治疗后在3个月内无症状或明显改善。3例（30%）患者因疼痛性肿块持续存在而接受了手术。在2例（66%）接受手术治疗的病例中，尽管等到影像学成熟指标出现后才进行切除，但术后仍有临床和影像学证据表明复发。
