Contusions and the Formation of Myositis Ossificans

In brief: Myositis ossificans—a benign process—is characterized by calcification of a hematoma that resulted from a severe contusion or strain or repeated trauma. Diagnosis is based on radiographic evidence of a calcified mass along with a history of recent trauma to the affected area. Management should be directed at minimizing or preventing extension of the original injury. Rest, ice, compression, and elevation (the classic treatment for any soft-tissue injury) is recommended as initial therapy. Gentle, painless range-of-motion exercises may be prescribed to help restore mobility. Padding can be used to protect the affected area from additional trauma.
