What is a Lisfranc Fracture/Dislocation?

The Lisfranc joint is an important structure in the foot that connects the metatarsal bones to the middle of the foot via several smaller joints. Within this joint lies the Lisfranc ligament which functions to provide critical mechanical stability to the foot.

Causes and Symptoms

Lisfranc injuries are usually the result of a traumatic event. Common causes include contact sports (such as football and lacrosse), car accidents, and missing a step on a staircase which cause the foot to twist out of place. These injuries can manifest as a sprain of the ligament, fracture (break in the bones), or dislocation. Symptoms often include pain, swelling, bruising, difficulty walking, and changes in foot structure.

Treatment

Treatment for a Lisfranc injury begins with non-surgical measures. These include:

• Cast immobilization
• Icing
• Elevation
• Anti-inflammatory medications (such as NSAIDS) to control swelling and pain

If a Lisfranc is severe or fails to respond to non-surgical treatment, surgical intervention is indicated. This can involve the use of plates or screws to realign the joints to the appropriate position followed by a period of immobilization. Due to the traumatic forces involved in Lisfranc injuries, it is not uncommon for the Lisfranc joint to suffer secondary arthritis which may need further surgery. Your foot and ankle specialist will choose the procedure which is right for you.
