title: Management of valgus extra-articular calcaneus fracture malunions with a lateral opening wedge osteotomy.
abstract: A total of 34 cases of symptomatic valgus deformity of the hindfoot secondary to a malunited extra-articular calcaneal fracture were corrected with laterally based open wedge calcaneal osteotomy. The pre- and postoperative radiographic parameters were compared, and a postoperative clinical evaluation was performed using the American Orthopedic Foot and Ankle Society ankle and hindfoot scoring system. The mean follow-up period was 56.2 (range 24.1 to 97) months. The most significant radiographic changes were improvement in the talonavicular coverage angle (mean 17.3°) on the anteroposterior view. The mean postoperative American Orthopedic Foot and Ankle Society hindfoot and ankle score was 90, with 23 excellent, 8 good, and 3 poor results. Laterally based opening wedge osteotomy of the calcaneus is effective in the management of a valgus heel resulting from malunited extra-articular calcaneal fractures. Lateral decompression of the peroneal tendons and the sural nerve was achieved indirectly through opening wedge lateral calcaneal osteotomy that shifted the weight-bearing axis laterally.
