The Lisfranc joint or tarsometatarsal joint refers to the region in the middle of the foot. It is a junction between the tarsal bones (seven bones in the foot arch) and metatarsal bones (five long bones in the foot). Injury to this region occurs if the bones are broken or ligaments that support the midfoot are torn.

Diagnosis

Diagnosis is made by medical consultation and examination, taking the patient's past medical history and physically inspecting the injured area. An X-ray may be taken to identify the location and severity of fracture. CT or MRI may also be requested to provide more information if required.

Treatment Options

Non Operative Treatment

If there are no fractures or dislocations in the joint and ligaments are not completely torn, non operative treatment may be all that is necessary for healing. Early stages of Lisfranc injury can be treated with rest, application of ice, elevation of your foot, immobilisation and anti-inflammatories if indicated.

Surgery

Injuries with displaced fractures (broken bones) or abnormal position (instability) of the joints are indicators of surgery. The goal is to realign the joints, return the fractured bone fragments to a normal position and restore stability to the midfoot. The fractured bones may be surgically aligned in the correct position and help with screws and pins, or a tarsometatarsal joint fusion may be recommended if all the non-surgical procedures have not been effective.
