This article describes a proximal phalangeal osteotomy for the correction of abductus deformity of the hallux. The modification uses a Z-osteotomy, which retains the length of the hallux, corrects the abductus component, and provides excellent rigid internal fixation. This procedure may be used only in mild-to-moderate cases. (J Am Podiatr Med Assoc 94(4): 404–408, 2004)
