Foot & ankle

Ankle diastasis without associated fracture occurs in a latent form in which the diastasis is detected only by stress radiographs, and in a frank form with the diastasis visible on routine, unstressed radiographs. Whereas latent ankle diastasis requires no reduction and can be treated by cast immobilization, frank diastasis requires anatomical reduction of the ankle mortise. The method of reduction depends upon the particular type of frank diastasis. ⋯ Good results were obtained in four patients. Fair results secondary to stiffness and pain on activity were present in two patients. All patients maintained anatomical reduction of the ankle mortise following removal of the tibiofibular screw.
