Lisfranc injuries result if bones in the midfoot are broken or ligaments that support the midfoot are torn. The severity of the injury can vary from simple to complex, involving many joints and bones in the midfoot.
The midfoot is the middle region of the foot, where a cluster of small bones forms an arch on the top of the foot. Five long bones (metatarsals) extend to the toes. The bones are held in place by connective tissues (ligaments) that stretch both across and down the foot. However, there is no connective tissue holding the first metatarsal to the second metatarsal. A twisting fall can break or shift (dislocate) these bones out of place.
The midfoot is critical in stabilizing the arch and in walking (gait). During walking, the midfoot transfers the forces generated by the calf muscles to the front of the foot.
The Lisfranc joint complex has a specialized bony and ligamentous structure, providing stability to this joint.
The most common symptoms of Lisfranc injury include:
- Swelling and tenderness on the top of the foot.
- There may be bruising on both the top and bottom of the foot. Bruising on the bottom of the foot is highly suggestive of a Lisfranc injury.
- Pain that worsens with standing or walking.
Treatment for a Lisfranc injury depends on the severity of the injury. If the bones have not been forced out of position, a cast or cam walker boot will need to be worn for four to six weeks. When the cast is removed, you may have to wear a custom orthotic.
Often, operative treatment is needed to stabilize the bones and hold them in place until healing is complete. Pins, wires or screws are options for fixation. Afterwards, you will have to wear a cast and limit weightbearing on the foot for six to eight weeks. In some cases, if arthritis develops in these joints, the bones may have to be fused together.
