An audit of lesser metatarsal osteotomy by capital proximal displacement (Weil osteotomy)

摘要

The post-operative predictability of the capital metatarsal displacement osteotomy has not been evaluated before by UK podiatrists. In this study 36 patients were evaluated using a score to rate the success of their surgery based on patient satisfaction scores. The scores correlated well (R2=0.94) with an American orthopaedic score rating for this audit. The proximal displacement osteotomy (PDO), also known as the Weil osteotomy, has been shown to be successful in reducing some keratinous lesions. In this study, 36% cleared completely. The procedure also created elevation of toes in 22% of cases studied (anatomical disturbance and mechanical reasons for toe instability are considered the main cause of elevation). Information provided by this audit study will contribute to evidence-based medicine in podiatry. The surgeon and patient will be guided by the likely outcome expected for this type of surgery. Data have been included for procedures undertaken with or without a concomitant first ray procedure. The foot surgeon must still consider the place of alternative procedures where failure of a PDO is likely to arise.
