The Silent Fracture: Recognizing and Managing Neglected Lisfranc Injuries
The Lisfranc joint, located between the midfoot and forefoot, is a complex structure responsible for crucial foot mechanics. A Lisfranc injury, involving a disruption of these ligaments and bones, can have debilitating consequences if left untreated. What makes this injury particularly challenging is its tendency to be neglected – often misdiagnosed or simply missed altogether. This article delves into the intricacies of a neglected Lisfranc injury, highlighting its impact and exploring strategies for effective management.
Understanding the Lisfranc Joint
The Lisfranc joint is formed by the articulation of the tarsals (bones of the midfoot) with the metatarsals (bones of the forefoot). This intricate network of ligaments and bones plays a vital role in:
- Supporting the arch of the foot: Providing stability and allowing for efficient weight distribution.
- Facilitating foot movement: Enabling the foot to adapt to uneven terrain and perform complex movements.
When the Lisfranc Joint is Compromised
A Lisfranc injury, also known as a Lisfranc fracture-dislocation, occurs when there is a disruption of these ligaments and bones, often due to a forceful twisting or impact injury. The resulting instability can lead to chronic pain, stiffness, and long-term functional limitations.
The Silent Nature of Neglected Lisfranc Injuries
The subtlety of symptoms often contributes to the challenge of diagnosing a Lisfranc injury, especially in its early stages. Many patients experience only mild pain and swelling, which may be attributed to a simple sprain or contusion. This delay in diagnosis can have serious consequences.
Dr. Daniel A. Geller, a leading expert in foot and ankle surgery, explains the risks of delayed diagnosis:

Identifying the Red Flags
While subtle, certain signs should raise suspicion of a Lisfranc injury and prompt further investigation:
- Pain and swelling: Particularly in the midfoot region, worsening with weight-bearing.
- Tenderness: Along the midfoot, especially near the articulation of the tarsals and metatarsals.
- Deformity: Visible angulation or misalignment of the foot.
- Bruising: Especially around the midfoot and arch.
- Limited range of motion: Difficulty with plantarflexion or dorsiflexion (pointing the toes up or down).
Diagnostic Tools
- X-rays: Essential for initial evaluation, though subtle fractures might be missed.
- MRI: Provides detailed imaging of soft tissues and bone structures, ideal for detecting ligamentous injuries.
- CT scan: Useful for visualizing complex fractures and bone alignment.
Managing Neglected Lisfranc Injuries
Treatment for a neglected Lisfranc injury depends on the severity and chronicity of the injury:
- Non-operative management: Suitable for stable injuries with minimal displacement. Includes immobilization, pain management, and rehabilitation.
- Surgical intervention: Required for unstable injuries with significant displacement. Often involves bone reduction (realignment), fixation (plates or screws), and ligament repair.

Rehabilitation and Recovery
Rehabilitation is crucial after any Lisfranc injury, especially following surgery. It involves:
- Weight-bearing restrictions: Gradual progression of weight-bearing as the injury heals.
- Physical therapy: Strengthening, range of motion exercises, and proprioceptive training.
- Custom orthotics: May be recommended for long-term support and stability.
The Long-Term Outlook
While recovery from a neglected Lisfranc injury can be challenging, with proper management and dedicated rehabilitation, many individuals can regain substantial foot function. However, it is important to acknowledge the potential for long-term complications, such as chronic pain, stiffness, and osteoarthritis.
Prevention is Key
While not always avoidable, understanding the risk factors for a Lisfranc injury can help minimize the chances of developing this potentially debilitating condition:
- High-impact activities: Particularly those involving forceful twisting or landing on an unstable surface.
- Improper footwear: Lack of adequate support or ill-fitting shoes can increase the risk.
- Underlying medical conditions: Conditions affecting bone health or ligament integrity.
Conclusion
A neglected Lisfranc injury poses a significant challenge for both patient and physician. Recognizing the subtle signs, seeking prompt diagnosis, and receiving appropriate treatment are critical for optimizing long-term outcomes. By understanding the complexities of this injury and prioritizing early intervention, we can minimize the potential for debilitating consequences and empower individuals to return to their desired levels of activity.
