Abstract
Purpose
Several techniques have been introduced for correction of pes cavovarus deformity. We retrospectively reviewed and compared the data of patients who underwent 1st metatarsal osteotomy alone, Dwyer's osteotomy alone, and 1st metatarsal osteotomy combined with Dwyer's osteotomy to determine the effect on radiographic parameters.
Materials and Methods
Data on 28 cases in 27 consecutive patients recruited from 2006 to 2014 who underwent 1st metatarsal osteotomy alone (group F), Dwyer's osteotomy alone (group H), or 1st metatarsal osteotomy followed by Dwyer's osteotomy (group HF) with a minimum 1-year follow-up were reviewed retrospectively.
Results
Calcaneal pitch angle on the standing foot lateral radiographs was significantly decreased after the operation in groups H and HF whereas Meary angle was decreased in groups F and HF. Hindfoot alignment angle and ratio on the hindfoot alignment view were improved in groups H and HF. Maximal medial cuneiform height reduction was observed in group HF. 1st ray was significantly shortened in groups F and HF.
