[Central fractures of the talus (author's transl)].
The results of the analysis of 52 central talar fractures and 37 follow-up cases in the 10 year material of the National Institute of Trauma are reported here. They point to the fact, that osteoarthritis can be avoided by appropriate treatment. Two aetiological factors in arthritis are the residual joint surface incongruence and the damage to the blood supply. Immediate, exact reduction and retention, even operatively if necessary and the delay of weight bearing until the restoration of blood supply and the bony architecture are recommended as preventive measures. If doubt arises on the diagnosis of damaged blood supply, intraosseous venography is recommended.
