Lisfranc (Midfoot) Fracture
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). Lisfranc fracture scan occur due to a fall from a height or traumatic motor accidents.
A midfoot fracture is characterized by pain and inability to bear weight. The appearance of bruises and swelling on the bottom of the midfoot are commonly observed symptoms. Your doctor will first examine the physical condition of the foot by inspection and palpation, then order X-rays, CT or MRI scans to provide more information about your condition.
The early stages of injury can be treated with rest, application of ice, elevation of your foot, NSAIDs and immobilization. The bones may be surgically aligned in 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.
Late presentation or missed Lisfranc injuries can lead to midfoot arthritis. The midfoot collapses and becomes stiff. Symptomatic relief at this stage can be gained with shoe modification, orthotics and corticosteroid injections. If the discomfort persists, the cure would be re-alignment of the midfoot with fusion of the involveed joints.
