Lisfranc (Midfoot) Fracture
What is the Lisfranc joint?
The tarsometatarsal joint refers to the region found in the middle of the foot. It is also called the Lisfranc joint. It is the junction between the tarsal bones (a group of seven articulating bones in the foot) and metatarsal bones (a group of five long bones in the foot).
What are the causes of Lisfranc fracture?
A fracture or deformity in the tarsometatarsal region can be due to arthritis or traumatic motor accidents.
Symptoms of Lisfranc fracture
Fractures due to tarsometatarsal arthritis are characterised by pain, functional impairment and midfoot instability. The appearance of bruises and swelling on the dorsal side of the midfoot are the commonly observed symptoms.
Diagnosis of Lisfranc fracture
The doctor will first examine the physical condition of the foot by inspection and palpation (feeling with hands). You may be advised to get an X-ray taken. You might also be sent to get a CT or MRI scan is done to provide more information about your condition.
Treatment of Lisfranc fracture
The early stages of injury can be treated with rest, application of ice, the elevation of your foot, NSAIDs and immobilization. The bones may be surgically aligned in the correct position and held with screws and pins, or a tarsometatarsal joint fusion may be recommended if all the non-surgical procedures fail to show efficacy in treating the injury.
