|
Purpose: Several techniques have been introduced for correction of pes cavo-varus 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.
Conclusion: Combined forefoot and hindfoot operation took the largest correction power of all radiologic parameters.
