[On myositis ossificans localisata and its operative treatment (author's transl)].

We observed 52 patients with myositis ossificans localisata partly of a traumatic, neurogenic or morbid (inflammable) origin. The fact that preferably young men are concerned in cases of traumatic and neurogenic myositis ossificans localisata is certainly not only caused by their increased exposition to trauma, but also by disposition. For indication and operative treatment it is necessary to classify as well as radiologically III different stages of development as respective groups of muscles. In posttraumatic and neurogenic cases relapses post operationem may probably be avoided in case, there is a radiological stage III (total development of muscle ossification).
