Ankle fractures: supination-eversion fractures of stage IV. Primary and late results of operative and non-operative treatment.

Supination-eversion fractures of stage IV, 60 treated operatively and 29 non-operatively, were seen at follow-up after 3-10 years. This disclosed a statistically significant difference between the results of the two methods. Operation which attempted to re-establish the anatomical position was apparently the better method in the presence of more than minimal displacement or a suspicion of deltoid ligament rupture.
