A Simple Method for Fixation of Proximal Opening-Wedge Osteotomy of the First Metatarsal for Correction of Hallux Valgus.

A simple, inexpensive technique for fixation of proximal opening-wedge osteotomy of the first metatarsal for correction of moderate or severe hallux valgus (HV) is described. After the opening-wedge osteotomy and bone grafting of the first metatarsal have been performed, 2 Kirschner wires are introduced for internal fixation and removed 8 weeks postoperatively. Twenty-three patients with symptomatic HV who had a proximal medial opening-wedge osteotomy of the first metatarsal in combination with a distal soft tissue procedure and bunionectomy were evaluated retrospectively. All osteotomies healed without complications and satisfaction was achieved in 22 patients. Hallux varus developed in 1 patient. Preoperatively, mean HV angle (HVA) was 41° (range, 35°-61°) and mean 1-2 intermetatarsal angle (IMA) was 19° (range, 16°-24°). Postoperatively, mean HVA was 14° (range, 10°-17°) and mean 1-2 IMA was 7° (range, 5°-9°). The mean decrease in the HVA was 27° (P<.001) and the mean decrease in the 1-2 IMA was 12° (P<.001).
