[Comparative anatomical result of conservative treatment and surgery in severe recent sprains of the ankle (author's transl)].

Severe recent sprains involving the lateral ligament of the ankle have been the object of numerous publications in recent years. Most authors have recommended the extension of the indications for open surgery. This lesion which was previously treated by immobilisation or even immediate physiotherapy is now operated on by numerous surgeons. In view of the very subjective character of the patient's opinion, and of the opinion of surgeons, it seemed logical to compare the radiological result in two series of similar severity operated on or treated by simple plaster immobilisation. One may note that the results observed are very similar, even when the accident gives rise to considerable separation of the tibio-talus joint line. Perhaps the figures published here will contribute to make surgery less often indicated.
