Soft tissue injury and myositis ossificans

Abstract Myositis ossificans (MO) is a benign, self-limiting condition characterized by the formation of bone tissue in soft tissues such as subcutaneous fat, tendons, and nerves. It typically occurs most commonly in muscles, presenting as a solitary ossifying soft tissue mass. This case report describes a young male patient who developed MO in the triceps muscle following trauma sustained a year prior. Due to restricted elbow range of motion and a palpable mass, surgical excision was performed, followed by adequate soft tissue coverage and postoperative physiotherapy. Diagnosis of suspicious soft tissue masses often requires multiple imaging modalities for accurate evaluation. In cases where imaging is inconclusive, a biopsy may be necessary for histologic confirmation, with histopathological findings varying depending on the stage of the lesion’s evolution. The management of MO is complex and typically involves a multidisciplinary approach to ensure accurate diagnosis and successful treatment outcomes.
