Minimally invasive surgery in the correction of recurrent hallux valgus: a case series with 2 year followup

Introduction: Recurrent deformity following surgical correction remains a complex and technically demanding condition. This studyaimed to evaluate the clinical and radiographic outcomes of minimally invasive surgery (MIS) in patients undergoing revision procedures for recurrent hallux valgus (HV). Methods: This retrospective case series included 33 feet that underwent minimally invasive revision surgery using either the thirdgeneration minimally invasive Chevron-Akin (MICA) or the fourth-generation Metaphyseal Extra-Articular Transverse and Akin osteotomies (META), following failure of a previous HV correction performed by open or MIS. Clinical outcomes were assessed using the Manchester-Oxford Foot Questionnaire (MOXFQ), the visual analog scale (VAS) for pain, and patient satisfaction. Radiographic parameters and complications were recorded and statistically analyzed using R software.Results: Both techniques proved effective in angular correction, with significant reductions in the hallux valgus angle (HVA) andintermetatarsal angle (IMA) (p 0.05). Conclusion: Third- and fourth-generation minimally invasive surgical techniques have proven effective in correcting radiographicparameters and improving pain and functional scores in patients undergoing revision for recurrent hallux valgus, with a low rate ofcomplications
