Lisfranc (Midfoot) Fracture

Definition: A Lisfranc fracture involves a break or dislocation in the midfoot region, specifically affecting the Lisfranc joint complex, which includes the bones and ligaments that connect the forefoot and midfoot. This type of injury can be severe and often impacts the stability and function of the foot.

Causes:

• Direct trauma, such as a heavy object falling on the foot
• High-energy injuries like car accidents or falls from a height
• Twisting injuries, particularly during sports activities

Symptoms:

• Severe pain in the midfoot, especially when standing or walking
• Swelling and bruising on the top and bottom of the foot
• Inability to bear weight on the affected foot
• Visible deformity or misalignment in the foot
• Tenderness when touching the midfoot

Diagnosis:

• Physical Examination: Assessing pain, swelling, bruising, and alignment.
• Imaging Tests: X-rays, CT scans, or MRI to confirm the fracture, dislocation, and extent of injury to the bones and ligaments.

Treatment:

• Immobilization: Using a cast or boot to stabilize the foot and allow healing.
• Non-weight Bearing: Avoiding weight on the affected foot, often with crutches or a wheelchair.
• Medications: Pain relievers and anti-inflammatory drugs to manage discomfort.
• Surgery: Required for severe fractures or dislocations to realign and stabilize the bones and ligaments with screws, plates, or pins.

Prognosis: Recovery from a Lisfranc fracture can be prolonged and may take several months. Proper treatment is crucial to avoid complications such as chronic pain, arthritis, and loss of foot function. Rehabilitation and physical therapy are often necessary to restore strength, flexibility, and mobility in the foot. Early and accurate diagnosis, along with appropriate treatment, can significantly improve outcomes and minimize long-term issues.
