Purpose: Several techniques have been introduced for correction of pes cavo-varus deformity. We retrospectively reviewed and comparedthe data of patients who underwent 1st metatarsal osteotomy alone, Dwyer’s osteotomy alone, and 1st metatarsal osteotomy combinedwith 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 osteotomyalone (group F), Dwyer’s osteotomy alone (group H), or 1st metatarsal osteotomy followed by Dwyer’s osteotomy (group HF) with aminimum 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 andHF whereas Meary angle was decreased in groups F and HF. Hindfoot alignment angle and ratio on the hindfoot alignment view wereimproved in groups H and HF. Maximal medial cuneiform height reduction was observed in group HF. 1st ray was significantly shortenedin groups F and HF. Conclusion: Combined forefoot and hindfoot operation took the largest correction power of all radiologic parameters.
