Talus necrosis and its treatment

 

Aetiopathogenesis of the necrosis of the talus has not yet been definitely clarified, and neither has that of the other aseptic necroses. We were able to study the aetiopathogenesis, course of the disease and therapy in 20 of our own patients by follow-up; two of these developed necrosis of the talus in both feet. We definitely excluded patients suffering from osteochondrosis dissecans. Even though fracture of the talus is on the whole relatively rare, it remains the most frequent cause of necrosis of the talus. We also found talonecrosis after surgical correction of clubfoot, after Sudeck's disease (Sudeck-Leriche syndrome, Sudeck's atrophy or dystrophy), suppurative arthritis of the ankle joint, subtalar luxation and haematogenic osteomyelitis. Only few patients required surgery. In most cases a special boot constructed for arthrodesis patients proved sufficient. Each patient developed arthrodesis to a different degree. Depending upon the complaints and stiffening of the ankle joint or of the talo-calcanonavicular joint, the capacity of the patients to be gainfully employed was reduced by an amount between 20 and 30 per cent.
