Radiologic findings in lesions of the ligamentum bifurcatum of the midfoot

Abstract

In a consecutive study of 106 patients presenting with a history of ankle sprain, 40.5% showed clinical signs of damage to the ligamentum bifurcatum. Eighteen of these patients showed 20 radiologic signs related to a lesion of this ligament; these signs included avulsions from the points of insertion and laxity in the lateral part of the transverse tarsal joint. The supplementary radiographs revealing these signs are demonstrated, and a more differentiated radiologic handling of the patient with ankle sprain is suggested.
