Popis: Myositis ossificans is non-neoplastic heterotopic bone forms in skeletal muscle. We recognize 3 subtypes: fibrodysplasia ossificans progressiva, myositis ossificans with no history of trauma (nontraumatic or pseudomalignant), and circumscribed or traumatic myositis ossificans. Traumatic myositis ossificans circumscripta has not, as far as we are aware, been previously documented as a complication of traumatic hip dislocation. We present the radiological findings of a 10-year-old girl with Thevenards syndrome, whose traumatic hip dislocation was complicated by circumstantial myositis ossificans. X-rays and computed tomography scan enabled us to diagnose by the presence of mature bone in the periphery of the lesion with a smooth contour and well separated from the bone. The treatment of dislocation and complication was nonoperatively.
