[Progressive myositis ossificans. Report of a case and results of treatment with disodium etidronate].

A new case of myositis ossificans progressiva is described. Authors emphasize the possibility of early diagnosis because there are characteristic malformations in this condition. Treatment with disodium etidronate (EHDP), proposed by some authors, had no clear benefit. Management of patients must concentrate on avoidance of exacerbating factors--muscle traumas--, physiotherapy and adequate psychotherapy.
