Lisfranc Injuries: Surgical vs. Non-Surgical Treatment Options - Orthopedics

More Info

---

Lisfranc injuries, which involve the midfoot and can affect the bones and ligaments that connect the metatarsals to the tarsal bones, are complex injuries that can significantly impact foot function. The decision between surgical and non-surgical treatment options depends on several factors, including the severity of the injury, the degree of displacement, and the patient's overall health and activity level.


Surgical vs. Non-Surgical Treatment Options
1. Non-Surgical Treatment:
- Indications: Non-surgical treatment is typically recommended for stable Lisfranc injuries where there is minimal displacement (usually less than 2mm) and no significant joint instability. In your case, with a 2.5mm displacement, this may be borderline for non-surgical management.

- Method: The most common non-surgical approach involves immobilization with a cast or a walking boot. This allows the bones to heal in their proper alignment. The duration of immobilization can vary, but it typically lasts for 6-8 weeks, followed by gradual weight-bearing as tolerated.

- Risks: The primary concern with non-surgical treatment is the potential for malunion or nonunion of the fracture, which can lead to chronic pain, instability, and arthritis in the affected joint. If the injury is not adequately stabilized, the risk of developing long-term complications increases.

2. Surgical Treatment:
- Indications: Surgical intervention is often indicated for displaced Lisfranc injuries (greater than 2mm), unstable fractures, or when there is a significant gap between the bones. Surgery aims to realign the bones and stabilize the joint using screws, plates, or other fixation devices.

- Method: The surgical procedure typically involves open reduction and internal fixation (ORIF) to restore the normal anatomy of the midfoot. This can be done through a minimally invasive technique or a more traditional open approach, depending on the injury's complexity.

- Benefits: Surgery can provide better alignment and stability, reducing the risk of long-term complications such as arthritis. Patients who undergo surgery often have a more predictable recovery and return to function.


Considerations for Your Decision
- Impact of Non-Surgical Treatment: If you choose non-surgical treatment, it's crucial to follow the immobilization protocol strictly. Regular follow-ups with imaging (like X-rays) will be necessary to monitor the healing process. If there are signs of malalignment or if symptoms persist, surgical options may need to be reconsidered.


- Long-term Outcomes: Studies have shown that patients with Lisfranc injuries treated non-surgically may have a higher risk of developing post-traumatic arthritis compared to those who undergo surgical fixation, especially if there is significant displacement. The long-term functional outcomes can vary widely based on the initial treatment approach and adherence to rehabilitation protocols.

- Consultation with Specialists: It may be beneficial to seek a second opinion from a foot and ankle specialist who has experience with Lisfranc injuries. They can provide insights based on the latest research and their clinical experience, helping you make an informed decision.


Conclusion
In summary, the choice between surgical and non-surgical treatment for a Lisfranc injury should be made after careful consideration of the injury's specifics and the potential risks and benefits of each approach. Non-surgical treatment can be effective for stable injuries, but it carries risks of complications that could affect long-term function. Surgical treatment may offer a more definitive solution, particularly in cases of significant displacement. Ultimately, the decision should align with your lifestyle, activity level, and personal preferences, and it is advisable to have thorough discussions with your healthcare provider to determine the best course of action for your specific situation.
