Progressive subtalar joint dislocation and limb-length inequality. An unusual case

Subtalar joint dislocation is a rare entity, accounting for only 1% of all traumatic dislocations. The authors report a case of an adolescent with gradual lateral subluxation of an anatomically abnormal subtalar joint with no history of trauma, an extremely rare presentation. The patient also had a congenitally short limb. The patient underwent llizarov leg lengthening along with multiple surgeries of the subtalar joint. The choice of the Ilizarov technique to lengthen the leg and realign the subtalar joint in this case is discussed.
