It is a junction between the tarsal bones (seven bones in the foot arch) and metatarsal bones (five long bones in the foot). Lisfranc fractures also known as 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.

What causes Lisfranc Fractures?
Lisfranc fractures a fracture of the calcaneus is most commonly due to a traumatic event such as falling from a height, twisting injury, motor accidents, sports injuries and ankle sprain.
Lisfranc fracture treatment
Lisfranc fractures are treated based on the type of fracture and extent of soft tissue damage.
- Rest, ice, compression, and elevation (R.I.C.E.) – is the most commonly used treatment option. Staying off (resting) the injured foot can heal the fracture to a great extent. Covering the affected area with ice packs over a towel reduces swelling and pain. Compression stockings and elastic bandages can also aid in healing the pain. Positioning the feet above the level of heart reduces swelling.
- Immobilization – Casting the injured foot prevents the fractured bone from moving. Walking with the help of crutches is advisable to avoid bearing body weight until healing has occurred.
- Open reduction and internal fixation – This surgery involves putting the bone fragments back together with metal plates and screws to reposition them and set them to normal alignment.
- Percutaneous screw fixation – This is the best preferred treatment in cases where the bone pieces are large. The bone can either be pushed or pulled to set into place without making a large incision. Metal screws are then inserted and fixed through small incisions to hold the bone pieces together.
