Revision surgeries for failed hallux valgus correction: A systematic review.
Failure of hallux valgus (HV) correction is not uncommon, and its management can be challenging. The available literature is not exhaustive. Therefore, we conducted a systematic review to investigate the current evidence on the role of revision surgery for failed HV correction, including clinical presentation, indications, surgical strategies and outcomes.The present systematic review was performed according to the PRISMA guidelines.
