The Lisfranc ligament is a very strong ligament that helps connect the long bones of the forefoot (metatarsals) to the bones of the arch (cuneiforms). This ligament helps maintain alignment of the forefoot and midfoot. Lisfranc ligament injuries can be very serious and should be evaluated immediately.
In order to properly treat these injuries it is necessary to determine the degree of tearing at the Lisfranc ligament. It is also important to identify associated joint dislocations in relation to the trauma. This process is completed by obtaining a thorough history and physical examination, plain film radiographs (X-rays) and advanced imaging (MRI/CT scan). Pain and swelling will undoubtedly be present. Often there will be an inability to bear weight on the injured limb.
Prompt immobilization and elevation will help reduce symptoms, but medication for pain and inflammation is typically needed. Surgery is not often indicated for isolated Lisfranc ligament sprains; however, a complete tear of the Lisfranc ligament or dislocation of the forefoot requires early surgical intervention. Your foot and ankle surgeon will determine the best treatment protocol to fit your needs.
