The offset V modification of the Chevron bunionectomy: a retrospective study.

This is a retrospective study of two different types of fixation for the offset-V modification of the Chevron (Austin) bunionectomy for correction of hallux abducto valgus deformity. Both screw fixation and Kirschner wire fixation were evaluated radiographically for hallux abductus angle, intermetatarsal angle, proximal articular set angle, tibial sesamoid position, and first metatarsal length. In addition, charts were reviewed for complications selective to each type of fixation. Radiographically, there was no apparent difference in preoperative and postoperative measurements between the two types of fixation. However, chart review led the authors to conclude certain advantages to screw fixation, in terms of clinical results and patient satisfaction.
