Causes

Lisfranc injuries can occur from twisting the foot and falling from heights. This injury is common in soccer and football players and often occurs when a person stumbles over, causing the foot to flex in a downward motion.

Severe types of this injury occur from direct trauma to the foot – for example, from falling from a height. These are high-energy damages that can result in multiple injuries, fractures and dislocations.

Signs and symptoms

Signs and symptoms of Lisfranc injuries include:

  • The top part of the foot may be painful and swollen
  • Bruising on the top or bottom of the foot
  • Worsening pain while standing or walking – the casualty may require crutches to walk

If standard treatment of relieving symptoms such as pain and swelling do not work, seek medical attention from an orthopaedic surgeon.

Tests and diagnosis

Physical findings of Lisfranc injury include:

  • Bruising along the bottom of the injured foot – this signifies a complete tear in the ligaments of the mid-foot or a fracture to the mid-foot
  • Tenderness upon applying pressure, also called palpation, along the mid-foot
  • Pain with stress. The doctor may grasp the heel of the affected foot and twist the front to determine if there is any pain. An uninjured foot will not hurt
  • A piano key test. The doctor will move the toes of the injured foot up and down to check whether it causes pain
  • Single limb heel rise. You may be asked to stand on one foot and try to rice on your toes. This will put stress on your mid-foot, if there is pain, you have a Lisfranc injury

Treatment

Most of the time treatment for a Lisfranc injury is done through surgery; however, minor injuries may be treated with first aid methods. Initially you may have to perform the RICE method: rest, ice, compress and elevate, to see if symptoms subside. If symptoms are persistent, you may have to seek medical attention and get surgical repair done.

For minimal displacement of the mid-foot structures, a stiff walking sling or cast may be applied for around 8 weeks. However, your doctor will most likely align the structures with screws or plates to support the mid-foot, which will be removed once treatment is complete.
