[Malignant degeneration of fistulas in chronic osteomyelitis (author's transl)].

The malignant degeneration of a skin ulcer has been reported as early as in 1884. In spite of this, however, the danger of malignant degeneration of sinus tracts associated with recurrences of chronic osteomyelitis is still underestimated. This development is neither restricted to case histories of years and decenniums nor to elderly patients and may also involve any part of the skeleton. Usually patients become aware of suddenly increasing tenderness and purulation, "washed out" structures of osteolytic areas are demonstrable radiographically. Diagnosis is established by mandatory histological examination of sinus tracts. Amputation or exarticulation of the extremity involved including efferent lymphatic vessels and nodi has no alternative. Local measures are insufficient. Apparently the first 3 years are decisive as to the prognosis. The prophylaxis consists of the therapy of the original disease: radical debridement of the osteomyelitic focus and filling of the defect with autogenous cancellous bone grafts.

The treatment of infected non-union of fractures of long bones. Study of sixty-four cases with a five to twenty-one-year follow-up.

The result of treatment of sixty-four patients with infected ununited fractures of long bone by debridement of soft tissue and bone and open suction-irrigation drainage, followed by rigid stabilization of the non-union and cancellous bone-grafting when indicated, was bone union in sixty cases, even in the presence of infection. The late results five to twenty-one years later showed good function despite the fact that prolonged periods of hospitalization were often required. The importance of local treatment of the infection prior to stabilizing the fracture fragments, and the use of cancellous bone grafts when necessary, are emphasized.

Evaluation of ankle fractures: non-operative and operative treatment.

A relatively great number of supination abduction fractures did not need surgical treatment because displacement was not present. Significantly better results occurred with operative intervention in supination--eversion and pronation--eversion ankle fractures. Supination--abduction and supination--eversion ankle fractures are best treated by open reduction, anatomical restoration and stabilization of the fractures.
