IntroductionLisfranc injuries form a distinct group of rare but severe injury. Literature suggests a low incidence, but failure to diagnose these injuries early and its subsequent delay in management will affect the patient's mobility and quality of life significantly. The preferred mode of management is said to be surgical. Conversely, the method of intervention for patients not suitable for surgery is less clear.AimThis study aims to evaluate the effect of delayed diagnosis and the treatment provided on the overall functional outcome for the patients with missed Lisfranc injury.MethodologyThe study was conducted at a specialist centre in the North-West of UK between January 2011 and November 2016. All patients with acute Lisfranc injuries were included in this study. Patient data was collected through electronic notes and analysed to ascertain missed diagnosis. It was also used to evaluate functional and radiological outcome.ResultsIn our series, 58.8% of Lisfranc injuries were missed on their initial presentation. We report better results for the surgical group when compared with the non-operated group, in spite of the delay in diagnosis.ConclusionWe believe that definitive treatment in the form of surgical fixation and anatomical reduction has more influence on the functional outcome than the timing of the surgical fixation in case of subtle Lisfranc injuries.
