About Lisfranc (Midfoot ) Injuries
- Lisfranc injuries occur in the midfoot.
- The Lisfranc joints are located between the long bones of the foot known as the first and second metatarsals and the medial and intermediate cuneiform. The Lisfranc ligament runs from the bottom of the medial cuneiform to the second metatarsal base.
- Lisfranc injuries can be extremely serious, and require immediate diagnosis and treatment to avoid complications.
The most serious complication is “compartment syndrome,” in which pressure builds in the tissues of the foot. Left untreated, compartment syndrome can cause tissue damage and damage to nerves, blood vessels and muscles.
- Arthritis and joint degeneration can also be caused by Lisfranc injury, although these generally take several months to develop.
UCSD's experienced orthopedic surgeons have extensive experience in the diagnosis of Lisfranc injuries, which are often mistaken for sprains. Prompt, accurate diagnosis is vital for successful treatment and recovery. Our physicians specialize in the treatment and follow-up care, including rehabilitation, required by Lisfranc and other midfoot injuries.
Causes
Lisfranc injuries can be caused by:
- High-impact trauma such as car or motorcycle accidents, industrial accidents or falls from high places
- Sports or activities in which you twist the foot during a fall, step into a hole, or someone steps on your foot
Symptoms
Often, Lisfranc injuries are mistaken for sprains. Symptoms can include:
- Swelling and bruising in the midfoot area; brusing on the arch of the foot
- Inability to put weight on the foot
- Pain when pressure is applied
If treatments such as rest, ice and elevating the foot don’t provide relief within a day or two of your injury, see an orthopedic specialist for proper diagnosis and treatment.
Treatment Options
Most Lisfranc injuries require surgery to repair the region and to decrease the risk of developing arthitis. Nonsurgical treatment is appropriate only for very mild injuries in which the bones haven’t been broken or displaced.
During surgery, the bones and joints are realigned properly and then secured with screws or pins. These screws or pins will be left in place for several months while the foot heals.
After surgery, you'll wear a cast for approximately eight weeks, followed by a removable boot for four to eight additional weeks. Your recovery will also include rehabilitation such as exercise and physical therapy.
