Abstract：
Myositis ossificans (MO) is a benign condition where bone forms within muscles due to increased activity of the periarticular tissues. Trauma is the most common cause. Nontraumatic MO is exceedingly rare. We present a rare instance of nontraumatic MO affecting the hip in a 32-year-old patient. The patient had a known case of seizure disorder and also had a history of a cerebrovascular accident (CVA). Despite the absence of trauma or known predisposing factors, the patient developed a sizable mass in the left hip, causing pain and restricted range of motion (ROM). Surgical excision of the mass was successful, resulting in complete removal and subsequent improvement in hip function and pain relief during postoperative recovery. Histopathological examination confirmed the diagnosis of MO. The patient\'s ROM normalized, and there were no signs of recurrence at the one-year follow-up. This case highlights the importance of recognizing MO in hip pain cases without trauma. Timely surgery through the approach described effectively removes the mass, preventing recurrence without compromising vital structures. It showcases a successful multidisciplinary approach for rare musculoskeletal conditions, offering valuable insights into similar cases.
摘要：
骨化性肌炎（MO）是一种良性疾病，由于关节周围组织的活动增加，骨骼在肌肉内形成。创伤是最常见的原因。非创伤性MO非常罕见。我们介绍了一名32岁患者的罕见非创伤性MO影响髋关节的情况。该患者已知有癫痫发作，并且有脑血管意外（CVA）的病史。尽管没有创伤或已知的诱发因素，病人的左髋部有相当大的肿块,引起疼痛和活动范围受限（ROM）。手术切除肿块成功,导致完全去除和术后恢复期间髋关节功能和疼痛缓解的后续改善。组织病理学检查证实了MO的诊断。病人的ROM正常化，在一年的随访中没有复发的迹象。此病例强调了在无创伤的髋部疼痛病例中识别MO的重要性。通过所描述的方法及时手术有效地去除肿块，在不损害重要结构的情况下防止复发。它展示了一种针对罕见肌肉骨骼疾病的成功多学科方法，为类似案例提供有价值的见解。
