Proximal Supination Osteotomy of the First Metatarsal for Hallux Valgus

Postoperative recurrence of hallux valgus is a relatively common complication and is associated with unsatisfactory surgical outcomes. Risk factors for postoperative recurrence include a round lateral edge of the first metatarsal head (a positive round sign) and incomplete reduction of the sesamoids. These risk factors may relate to residual pronation of the first metatarsal following surgery. A novel technique of a proximal supination osteotomy, in which varus and pronation of the first metatarsal can be corrected simultaneously, can achieve significant correction in moderate or severe hallux valgus deformity and a low rate of hallux valgus recurrence.
