Fourth-generation percutaneous or minimally invasive hallux valgus surgery utilizes a transverse osteotomy to achieve deformity correction. There are only a small number of series reporting the clinical and radiological outcomes of transverse osteotomies, many of which have methodological limitations such as small sample size, limited radiographic follow up or use of non-validated outcome measures. The aim of this study was to provide a methodological robust investigation into percutaneous transverse osteotomies for hallux valgus deformity. A prospective series of consecutive patients undergoing fourth generation metatarsal extra-capsular transverse osteotomy (META) performed by a single surgeon (PL) between November 2017 and January 2023. The primary outcomes were radiographic deformity correction and clinical foot function assessed using the Manchester-Oxford Foot questionnaire (MOXFQ). Radiographic deformity (Hallux valgus angle (HVA) and intermetatarsal angle (IMA), sesamoid position) was assessed according to AOFAS guidelines. Secondary outcomes included Visual Analogue Scale for Pain and radiographic deformity recurrence (defined as HVA >20° at final radiographic follow up).Background
