Abstract

The use of «scarf» osteotomy in 9 patients (14 feet) with valgus deformity of great toe was analysed. That technique was showed to provide stable correction of varus deviation of the first metatarsal bone and valgus deformity of the great toe as well as correction of the length of the first metatarsal bone and elimination of its pronator rotation without development of avascular necrosis of the head in postoperative period. Rigid fixation of bone fragments provides the possibility of early activization and rehabilitation of patients.
