Lisfranc injury
Pronunciation: LIS-frank
Injury to the midfoot involving disruption of the tarsometatarsal joints and associated ligamentous structures.
Full Definition
A Lisfranc injury involves damage to the tarsometatarsal joints in the midfoot, named after Jacques Lisfranc who first described the anatomical complex. These injuries can range from subtle ligamentous sprains to complete joint dislocations with fractures. In sports medicine, Lisfranc injuries are often missed initially due to their subtle presentation but can result in significant long-term disability if not properly diagnosed and treated. They commonly occur in sports involving pivoting, cutting, or direct trauma to the midfoot.
Usage
Usage note: Capitalize 'Lisfranc' as it is an eponymous term; distinguish from simple midfoot sprains.
