CONTRAINDICATIONS: Rigid flatfoot deformity (posterior tibial tendon dysfunction stage III and IV). Talocalcaneal and naviculocalcaneal coalition. Osteoarthritis of calcaneocuboid joint.

SURGICAL TECHNIQUE: Exposition of calcaneus at sinus tarsi. Osteotomy through sinus tarsi and widening until desired correction of the foot is achieved. Insertion of bone graft. Screw fixation.

POSTOPERATIVE MANAGEMENT: Immobilization in a cast for 6 weeks. Weight-bearing as tolerated from the beginning.
