A Lisfranc injury is a cause of foot pain that may be difficult to diagnose. This infrequent foot injury occurs when there is high energy trauma to the top of the foot. This trauma may occur in road traffic accidents or during sports such as soccer when a player kicks the sole of an opponents boot. Because of the history of direct trauma to the top of the foot it is difficult to differentiate from a Tarsal bone fracture or bone bruising. There may or may not be a swollen foot.
Treatment is dependent on the severity of the injury. If there is a sprain of the Tarso Metatarsal ligament, with no widening of the Metatarsals evident on x-ray , then conservative management should suffice. Where there is more severe Tarso-Metatarsal ligament damage, the prognosis is not so good. This ligament damage causes instability at the Lisfranc joint complex, which is evident on x-ray as widening between the Tarso-Metatarsal joints. Many orthopaedic consultants advocate surgical fixation to reduce the likelihood of developing arthritis of the foot.
