title: Opening base wedge osteotomy of the first metatarsal utilizing rigid external fixation.
abstract: The authors describe their operative approach to metatarsus primus adductus deformity when present in conjunction with a congenitally short first metatarsal. Hallux abducto valgus correction in this clinical setting has traditionally advocated use of a crescentic or opening wedge osteotomy in order to prevent further shortening of the first metatarsal. Fixation of opening base wedge osteotomies has been fraught with problems in the past, with possibilities for displacement or eventual loss of initial correction. The authors have found the mini-Hoffmann external fixation device useful for this purpose.
