Understanding Lisfranc Injuries: Causes, Symptoms, and Treatment Options
When it comes to foot injuries, Lisfranc injuries are among the most complex and often misunderstood. Despite their name’s rarity in everyday conversation, these injuries are a significant cause of midfoot pain and dysfunction. At Rocky Mountain Orthopedics of Utah, we aim to educate our patients about such conditions to help them recognize the signs and seek timely treatment.
What Is a Lisfranc Injury?
The Lisfranc joint complex is a critical structure in the midfoot, named after Jacques Lisfranc, a French surgeon. It involves a network of small bones (the tarsometatarsal joints) and their supporting ligaments that connect the forefoot to the midfoot. This area plays a vital role in stabilizing the arch of the foot and transferring weight during walking or running.
A Lisfranc injury occurs when the bones or ligaments in this region are damaged. This can range from simple ligament sprains to severe fractures and dislocations of the bones in the midfoot.
Causes of Lisfranc Injuries
Lisfranc injuries can result from both low-energy and high-energy trauma, including:
- Twisting or falling injuries: A common scenario involves tripping or twisting the foot while it’s flexed downward, such as when stepping off a curb awkwardly.
- Direct trauma: High-impact injuries, such as those sustained in car accidents or falls from significant heights, can also cause Lisfranc damage.
- Sports injuries: Athletes in sports that require rapid changes in direction or high-force impact, such as football or soccer, are at increased risk.
Recognizing the Symptoms
Symptoms of Lisfranc injuries can vary depending on the severity, but common signs include:
- Midfoot pain: This is often severe and worsens with standing or walking.
- Swelling and bruising: Bruising on the bottom of the foot is a hallmark of Lisfranc injuries.
- Difficulty bearing weight: Patients may find it painful or impossible to put weight on the affected foot.
- Visible deformity: In more severe cases, there may be noticeable misalignment in the midfoot region.
Diagnosing Lisfranc Injuries
Diagnosing a Lisfranc injury involves a combination of:
- Clinical examination: Your specialist will assess pain points, stability, and alignment of the midfoot.
- Imaging: X-rays, CT scans, or MRIs may be needed to confirm the diagnosis, especially if the injury is subtle. Weightbearing X-rays can be particularly useful for identifying misalignment that might not be visible in non-weightbearing images.
Treatment Options
Treatment for Lisfranc injuries depends on the severity of the damage:
- Non-surgical treatment: Minor injuries, such as sprains or stable fractures, may be treated with immobilization in a cast or boot for 6–8 weeks, followed by physical therapy to restore strength and mobility.
- Surgical intervention: Severe injuries involving fractures, dislocations, or ligament tears typically require surgery to realign and stabilize the joint. Procedures may include open reduction and internal fixation (ORIF) or fusion of the affected joints. Below is an example of the before and after of a Lisfranc repair. The space between the bones has been reduced and the joints are aligned.
Recovery and Prognosis
Recovery from a Lisfranc injury can be lengthy, often taking several months to a year. Factors that influence recovery include the severity of the injury, the treatment approach, and adherence to rehabilitation protocols. It’s important to follow your specialist’s guidance to reduce the risk of complications such as arthritis or chronic pain.
When to See a Specialist
If you experience persistent midfoot pain, bruising, or difficulty bearing weight after an injury, it’s crucial to consult a foot and ankle specialist promptly. Early diagnosis and treatment are key to preventing long-term complications.
