[The treatment of severe talus fracture-dislocations and peritalus dislocations].

Twenty-eight cases with severe talus fracture-dislocation and 17 cases with peritalus dislocations were treated and were followed up with an average of 7 years and 2 years plus 5 months for these two groups respectively. Comparison of the results of treatment in the cases with severe talus fracture-dislocations with 3 different methods (reduction and immobilization, total talus resection and arthrodesis) was made. Satisfactory result was obtained only in cases treated with arthrodesis, therefore, this method should be considered at first in the treatment of severe talus fracture-dislocations. Impaction of intraarticular fragments and soft tissues are usually the indications of open reduction for peritalus dislocations. Severity of injury accompanied with intraarticular fractures, and open injury are the factors influencing the prognosis. Different from severe talus fracture-dislocations, talus avascular necrosis did not occur in cases with peritalus dislocations.
