Lisfranc injury

Lisfranc Injury

Lisfranc injury (pronounced: liz-frank) is a type of foot injury that occurs when one or more of the metatarsal bones are displaced from the tarsus. The term "Lisfranc" is derived from the name of French surgeon Jacques Lisfranc de St. Martin, who first described this injury in the 19th century.

Definition

A Lisfranc injury involves damage to the Lisfranc joint, which is the point at which the metatarsal bones (long bones that lead up to the toes) and the tarsal bones (bones in the arch of the foot) connect. The injury can range from a simple sprain to a complex dislocation that requires surgical intervention.

Causes

Lisfranc injuries can occur as a result of direct or indirect forces to the foot. Direct force often involves a heavy object falling on the foot, while indirect force can occur when the foot is planted and twisted.

Symptoms

Symptoms of a Lisfranc injury may include pain and swelling in the midfoot area, inability to bear weight on the affected foot, bruising on the bottom of the foot, and abnormal widening of the foot.

Treatment

Treatment for a Lisfranc injury depends on the severity of the injury. Non-displaced injuries can often be treated with immobilization and non-weight bearing, while displaced injuries usually require surgical intervention.
