Within the foot, there are various structures that serve an array of functions. One found in the midfoot is the Lisfranc joint complex. At our Nassau County podiatrist office, we sometimes treat patients for midfoot injuries that happen in the complex, but find that few people are actually aware of this particular structure and what it does for their feet.
Basically, the Lisfranc joint complex is the place where the tarsal bones and metatarsal bones connect in the midfoot. The tarsals are the ones found on the top of the foot that support the arch, while the metatarsals are the long, thin bones that bridge the hindfoot and the toes. At the point where they meet, there is a tough band of fibrous tissue known as the Lisfranc ligament. This ligament is responsible for providing strength and proper alignment to the joint, but it does not actually hold the first and second metatarsal bones together.
The complex itself is responsible for stabilizing the foot arch and enabling walking and other foot movement. This area of the foot also transfers forces that are generated by the calf muscles down to the forefoot region.
There are various midfoot injuries that can potentially happen in the complex, including sprains, fractures, and dislocations. Most of the injuries are the result of the foot twisting beyond a reasonable range of motion. Sprains happen when connective tissues are excessively stretched and lead to instability in the joint.
Any of the bones that form the Lisfranc joint can be fractured when exposed to sufficient trauma, either in a single incident or over time. These bones are also susceptible to avulsion fractures – where a tiny piece of bone is ripped off from a metatarsal or tarsal bone.
If the midfoot is subjected to tremendous amounts of force, the bones can become dislocated from their normal position.
