Differenti metodi di intervento nella correzione dell'alluce valgo: Valutazione dei risultati clinici different surgical techniques for correction of hallux valgus deformity: Clin-Ical results

Aim: The aim of the study was to compare the mid term results of different surgical techniques for the correction of mild to moderate hallux valgus deformity. Methods: Two hundred and seven patients, monolaterally operated for correction of hallux valgus deformity at the Department of Orthopaedic Surgery of the University of Milan (Italy)-IRCCS Policlinico San Donato in the years 2000-2005, were retrospectively clinically re-evaluated. Different surgical techniques were employed (distal osteotomies and soft tissue procedures); proximal metatarsal and percutaneous osteotomies were excluded. Both American Orthopaedic Foot and Ankle Society (AOFAS) objective score and Foot Function Index (FFI) subjective index were used for clinical evaluation. Results: One hundred and nine patients were reviewed (96 females and 13 males) spanning the ages between 37 and 83 years; 34 of them have been treated by distal chevron osteotomy according to Austin, 33 by osteotomy according to Reverdin-Green, 17 have been operated on with the technique described by Regnauld, 16 by Lelièvre operation and 9 have been treated according to Viladot (but this last cohort of patients was not considered in the statistic evaluation due to such a small number). Clinical results were very similar for the four aforementioned main techniques: for the Lelièvre method only the global functional scores were slightly lower. Conclusion: From these results it is not possible to draw definite conclusions regarding the best surgical method for treatment of hallux valgus deformity; however, when a more aggressive technique is used, with sacrifice of the articular cartilage, the functional results are worse.
