足関節脱臼骨折の治療成績

抄録

The results of operative treatment for 78 fracture-dislocations of the ankle joint were assessed. According to Lauge-Hansen classification of ankle fracture, 25 (32%) were SER type, 33 (42%) were PER type, 6 (7.7%) were SA type, 10 (12.8%) were PA type, and 3 (3.8%) were PD type.
Noncomminuted spiral fractures of the fibula were fixed with an intramedullary K-wire combined with half circular wire fixation, while fractures of the medial malleolus were fixed using the tension band technique. Immobilization with a plaster cast was maintained for 4-5 weeks postoperatively.
More than 85% of the patients showed a good result by radiographic and objective assessment.
We conclude that satisfactory results can be obtained by anatomical reduction of the fibular and medial malleolar fractures, and that delayed mobilization is not an adverse factor as long as satisfactory anatomical reduction is maintained.
