MYOSITIS OSSIFICANS TRAUMATICA
AUGUSTUS THORNDIKE JR. M.D., F.A.C.S.1

1. Myositis ossificans traumatica is an inflammatory process of muscle in its early stages and before ossification is actually demonstrated by the roentgen ray. "Tumor", "dolor", and "calor" are all present at this stage.
2. This inflammatory process gradually subsides as ossification takes place.
3. The ossification is gradually absorbed in part and sometimes in full, depending upon its size and location. The muscle function returns to normal, except in those instances where the ossification occurs near a joint.
4. Treatment necessitates the immediate application of cold and a compression bandage to control hemorrhage, and later heat to aid in the absorption of the hematoma. Of great importance is the avoidance of massage on all severe and tender muscle contusions.
5. Operative removal of the ossification is indicated only in those cases in which it occurs near a joint in the origin or the insertion of a muscle, where joint function is permanently impaired, and then only from twelve to twenty-four months after the injury.
