[Non-traumatic circumscribed myositis ossificans. Apropos of a bilateral localization]. / La myosite ossifiante circonscrite non traumatique. A propos d'une localisation bilatérale.

The authors report one case of a bilateral atraumatic circumscribed myositis ossificans (C.M.O.) developed from the triceps muscles with major equinism, in a 15 years old girl. One side presented a current tumor, the other was seen at the first episode. The authors obtained a good functional result after surgical treatment and advocate this treatment.
