Abstract

Ball-and-socket deformity of the ankle joint is a rare entity that is usually associated with inequality of leg length, fibular hyperplasia, coalition of the ankle, and ray deficiency. Etiology is unknown, congenital itself or secondary to congenital conditions in the ankle. Nonunion of medial malleolar is rare in bilateral ball and socket ankle joint without lower leg deformity. We report upon this case, and include brief reviwe of the literature.
