title: Nontraumatic myositis ossificans in healthy individuals.
abstract: Myositis ossificans has been subclassified into three categories: traumatic, progressive, or those cases associated with neuromuscular and chronic disease. Four cases of myositis ossificans occurred in otherwise healthy individuals without any history of trauma. These four patients illustrate a fourth and distinct subclassification of the disease.
