Distinguishing stable from unstable ankle fractures is key to successful ankle fracture management. Gravitational stress views (GSV) may be a convenient and less painful alternative to manual stress testing. The aim of this study was to assess whether this test accurately predicts ankle instability. Patients presenting to a single trauma centre between 2011 and 2013 with an isolated fibula fracture and a an anatomically-aligned mortise on initial plain film radiographs were reviewed. After initial x-ray, patients underwent a gravity stress view. Measurements from plain film radiographs were recorded and analysed. Electronic case notes and National Imaging Archives were reviewed retrospectively at a minimum of 10 years post-injury. Patients were contacted to complete patient reported outcome measures (PROMS).Background
