| Abstract: | BackgroundHaving had a previous experience of 4 open F2 osteotomies to correct interphalangeal hallux valgus, the aim of this study was to test the efficacy of a percutaneous approach for this correction.Methods3 open and 12 percutaneous F2 osteotomies in 15 cadaver feet were performed. Interphalangeal (IPH), F2 asymmetry (AF2) and joint deviation (JD) angles were measured on radiographs. The operated great toes were anatomically analyzed looking for possible lesions to surrounding tissues.ResultsMean IPH decreased from 10.7° to 2.9°, AF2 from 7.8° to 1°, and JD from 1.4° to 0.5°. Damage to the hallux extensor tendon was detected in 1 foot and a nail bed lesion was detected in 1 case, both operated percutaneously.ConclusionsF2 Valgus deformity can be corrected using open or percutaneous osteotomy. The authors consider the open correction worthwhile because percutaneous techniques may damage surrounding tissues and the incision length difference is minor.Level of clinical evidence: 3. |
