Abstract
OBJECTIVE: Lengthening of the lateral column for adduction of forefoot and restoration of the medial arch. Stabilization of the ankle joint complex. INDICATIONS: Supple flatfoot deformity (posterior tibial tendon dysfunction stage II). Instability of the medial ankle joint complex (superficial deltoid and spring ligament). Posttraumatic valgus and pronation deformity of the foot. 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. RESULTS: In the majority of cases, part of hindfoot reconstruction. Reliable and stable correction. Safe procedure with few complications.
