Do columns or sagittal displacement matter in the assessment and management of Lisfranc fracture dislocation? An alternate approach to classification of the Lisfranc injury

Abstract

AIM: The classification of a Lisfranc injury has conventionally been based around Myerson's system. The aims of this study were to review whether a novel classification system based on sagittal displacement of the tarsometatarsal joint and breadth of injury as determined by a columnar theory was associated with functional outcomes and thus had a greater utility. PATIENTS: We retrospectively reviewed 54 Lisfranc injuries with a minimum follow up of two years at our Level One Trauma Centre. Each fracture was sub-classified based on our novel classification system which assessed for evidence of sagittal displacement and involvement of columns of the midfoot. Our primary outcome measures were th..
