Subtalar Dislocation

Abstract

During the period from 1945 to 1972, 30 cases of subtalar dislocation were reported to the Directorate of Industrial Injuries Insurance in Denmark. The lesions were classified according to type of dislocation showing that the medial inward type predominated by far. According to the findings of the present investigation, the long-term prognosis seems to be more serious than has hitherto been assumed. X-ray and clinical examination disclosed that arthrosis of the subtalar joints was demonstrable in 19 patients. Six of these patients had pantalar arthrosis, the causative factor in two cases being avascular necrosis of the talus. Clinical examination showed that walking was associated with some degree of pain in 21 patients and 15 patients had a more or less pronounced limp.
