Take Home Points

A Lisfranc injury is a midfoot injury that results in displacement of one or more of the metatarsal bones from tarsus. 
XR will show widening of the space between the 1st and 2nd metatarsals. Getting contralateral XR may help you identify this.
Even if you don’t see that widening on the XR, the patient could still have a Lisfranc injury. If they cannot walk due to pain, get a weight bearing XR or CT scan to look further.
Once the injury is identified, the patient must be strict non-weightbearing. Place them in a posterior splint and get orthopedics involved either in the ED or for prompt follow up as the patient will probably need surgery.
