Effect of Subtalar Fusion and Calcaneal Osteotomy on Function, Pain, and Gait Mechanics for Calcaneal Malunion.

Background: Calcaneal malunion is a common complication of nonoperative management of calcaneal fracture, which leads to a disruption of the biomechanics of the lower extremity, pain, and permanent disability. Our aim was to evaluate pain, function, and gait after combined subtalar joint fusion, calcaneal osteotomy, and lateral wall exostectomy for patients with neglected calcaneal fractures with malunion.

Methods: Eighteen patients with malunited calcaneal fractures, varus deformity, and subtalar arthritis were operated upon and then followed up for 18 months.

Foot and ankle function after tibial overlengthening.

Lengthening the tibia more than 25% of its original length can be indicated for proximal femoral deficiency, poliomyelitis, or femoral infected nonunion. Such lengthening of the tibia can adversely affect the ankle or foot shape and function. The present study aimed to assess the effect of tibial lengthening of more than 25% of its original length on the foot and ankle shape and function compared with the preoperative condition.
