What Is a Lisfranc Injury?
The Lisfranc joint complex — named after French field surgeon Jacques Lisfranc de St. Martin who described midfoot amputations in the Napoleonic era — comprises the articulations between the five metatarsal bases and the three cuneiforms and cuboid. Together, these joints form the foundation of the transverse and longitudinal arches of the midfoot.
Lisfranc injuries encompass a spectrum from subtle ligamentous sprains with minimal displacement to complete fracture-dislocations with significant structural disruption. The Lisfranc ligament itself — a strong interosseous structure connecting the medial cuneiform to the second metatarsal base — is the primary stabilizer of this complex and the structure most commonly injured.
These injuries are notoriously underdiagnosed: an estimated 20–40% of Lisfranc injuries are missed on initial evaluation because non-weight-bearing x-rays may appear normal. Weight-bearing imaging and high clinical suspicion are essential for accurate diagnosis.
How Lisfranc Injuries Occur
Lisfranc injuries result from two primary mechanisms:
- Low-energy indirect mechanism — the most common presentation in the general population. A simple twist, stumbling in a pothole, or missing a step can deliver a rotational force through the midfoot with the ankle plantarflexed. The foot is fixed to the ground while the body rotates over it. This mechanism is frequently involved in the “stepping in a hole” or “ballet slip” mechanism seen in dancers.
- High-energy direct mechanism — crush injuries (industrial accidents, MVAs, falls from height) with direct force applied to the dorsum of the foot. These injuries produce more severe fracture-dislocations with greater displacement and comminution.
In athletes, Lisfranc injuries are particularly common in American football (linemen low-energy twisting injuries), equestrian riders (foot caught in stirrup), and soccer players. They are often initially dismissed as midfoot sprains and undertreated.
The Spectrum of Lisfranc Injury Severity
Lisfranc Sprain (Stable)
Disruption of the Lisfranc ligament without diastasis (gap) between the first and second metatarsal bases or displacement of the TMT joints. Weight-bearing x-rays show no widening. MRI confirms ligament disruption but no instability. These injuries can be managed non-surgically with strict non-weightbearing in a cast or boot for 6–8 weeks, followed by progressive rehabilitation.
Partially Unstable Lisfranc Injury
Partial ligamentous disruption with subtle (1–2mm) diastasis or instability demonstrated on stress testing or weight-bearing views. These injuries are at risk for progression and typically benefit from surgical stabilization, particularly in athletic patients or those with high functional demands.
Unstable / Displaced Lisfranc Fracture-Dislocation
Complete ligamentous disruption with visible widening of the first-second metatarsal interspace on weight-bearing x-ray, or frank dislocation of one or more TMT joints. These injuries require surgical fixation without exception. The homolateral pattern (all metatarsals displaced in the same direction), divergent pattern (medial and lateral columns displaced in opposite directions), and isolated column injuries are distinct subtypes with different fixation strategies.
Diagnosis: Why These Injuries Are Missed
Lisfranc injuries are missed because:
- Non-weight-bearing x-rays are often normal — the injured foot must bear weight for the instability to become radiographically apparent.
- Pain and swelling lead patients and physicians to conclude it is “just a sprain.”
- The classic “plantar ecchymosis” sign (bruising on the plantar midfoot) — highly specific for Lisfranc injury — is often not looked for.
Dr. Biernacki’s evaluation protocol for suspected Lisfranc injury includes:
- Clinical examination — direct palpation of the second TMT joint, midfoot stability testing, and inspection of the plantar midfoot for ecchymosis.
- Weight-bearing foot radiographs — the single most important diagnostic study. Diastasis ≥2mm between the first and second metatarsal bases on AP view confirms instability.
- MRI — for indeterminate cases; demonstrates Lisfranc ligament integrity and excludes associated injuries (plantar fascia, TMT joint cartilage).
- CT scan — optimal for surgical planning in complex fracture-dislocations; characterizes bony anatomy, fragment size, and comminution.
Non-Surgical Treatment
Stable Lisfranc sprains (confirmed by negative weight-bearing x-ray and MRI showing partial ligament disruption without diastasis) may be managed non-surgically:
- Non-weightbearing in a short-leg cast for 6–8 weeks.
- Progressive weight-bearing in a removable boot from weeks 8–12.
- Custom orthotics with midfoot support for 12+ months following return to weightbearing.
- Physical therapy for proprioception, arch strengthening, and return to sport.
Non-surgical treatment of truly stable Lisfranc injuries produces acceptable outcomes in most patients. Missed unstable injuries treated non-surgically develop midfoot collapse, chronic pain, and arthritis — making accurate diagnosis critical.
Surgical Treatment
Unstable Lisfranc injuries require anatomic reduction and stabilization to prevent midfoot collapse and arthritis:
Open Reduction and Internal Fixation (ORIF)
Through dorsal incisions, the displaced TMT joints are reduced anatomically and stabilized with screws and/or plates. The Lisfranc screw — placed from the medial cuneiform to the second metatarsal base — is the cornerstone fixation. Hardware stabilizes the midfoot during ligament healing. Depending on injury pattern, medial and/or lateral column fixation may be required. ORIF achieves anatomic alignment critical to preventing post-traumatic arthritis.
Lisfranc Fusion (Primary Arthrodesis)
For severely comminuted injuries, elderly patients, or injuries with articular cartilage destruction, primary fusion of the medial column (first, second, and/or third TMT joints) produces reliable pain relief without the hardware removal step. The lateral TMT joints (fourth and fifth) are generally not fused to preserve motion important for uneven terrain ambulation.
Recovery and Outcomes
Lisfranc recovery is among the longest in foot and ankle surgery:
- Weeks 0–8: Non-weightbearing in cast or boot. Elevation.
- Weeks 8–12: Progressive weightbearing in boot.
- Month 3–6: Transition to shoes with supportive orthotics. Screw removal (if applicable) often performed at 3–6 months.
- Month 6–12: Return to sport and high-demand activity.
Outcomes depend critically on injury severity and quality of reduction. Anatomically reduced and stabilized injuries produce significantly better outcomes than displaced injuries or those with delayed diagnosis. Post-traumatic midfoot arthritis develops in a substantial percentage of patients regardless of treatment — its severity directly correlates with residual displacement at the time of healing.
Dr. Tom’s Product Recommendations

✅ Pros / Benefits
- Early accurate diagnosis and anatomic reduction of unstable Lisfranc injuries dramatically reduces post-traumatic arthritis risk
- Weight-bearing radiographs are essential and inexpensive — the most critical diagnostic step in Lisfranc evaluation
- Stable Lisfranc sprains treated correctly with non-weightbearing achieve good outcomes and avoid surgery entirely
❌ Cons / Risks
- Even optimally treated Lisfranc injuries carry a significant risk of post-traumatic midfoot arthritis — realistic long-term prognosis counseling is essential
- Recovery is prolonged — 6–12 months for return to full activity — requiring planning for work leave and activity modification
- Missed or undertreated unstable Lisfranc injuries produce severe midfoot collapse and chronic disability — second opinions on midfoot ‘sprains’ with ongoing pain are warranted
Dr. Tom Biernacki’s Recommendation
The thing that keeps me vigilant about Lisfranc injuries is how often they’re missed. A patient comes in, non-weight-bearing x-ray looks okay, they’re told it’s a sprain and to rest it. Three months later they’re still in pain and now they have a midfoot that’s slowly collapsing. When someone has midfoot pain that’s worse with weight-bearing and I see plantar bruising, the Lisfranc complex is my first suspicion until proven otherwise. Weight-bearing x-ray, MRI if there’s any doubt. The cost of missing this injury is enormous — the cost of imaging to catch it is minimal.

Frequently Asked Questions
How do I know if I have a Lisfranc injury?
Lisfranc injury typically presents as midfoot pain — pain in the central arch and base of the metatarsals — that is dramatically worse with weight-bearing. A classic sign is bruising on the bottom of the foot (plantar ecchymosis). If you twisted your foot and have midfoot pain worse with walking, especially if there’s plantar bruising, seek podiatric evaluation urgently.
Can a Lisfranc injury heal without surgery?
Yes — stable Lisfranc sprains without diastasis can heal non-surgically with strict non-weightbearing for 6–8 weeks. However, unstable injuries (identified on weight-bearing x-ray as diastasis ≥2mm) require surgery. The key is accurate classification — non-operative management of an unstable injury leads to poor outcomes.
How long does it take to recover from a Lisfranc injury?
Return to normal footwear typically takes 3–6 months; return to full sport or high-demand activity takes 6–12 months. Even after healing, some patients have residual midfoot stiffness or soreness with prolonged activity for 1–2 years.
Do I need to see a podiatric surgeon for a Lisfranc injury?
Evaluation by a foot and ankle specialist is strongly recommended for suspected Lisfranc injury. These injuries require weight-bearing imaging not always obtained in urgent care settings, and accurate classification by an experienced clinician is essential for appropriate treatment decisions.
What happens if a Lisfranc injury goes untreated?
Untreated unstable Lisfranc injuries result in progressive midfoot arch collapse, post-traumatic arthritis, chronic pain, and significant functional disability. Patients may ultimately require midfoot fusion to achieve acceptable pain relief after collapse — a much larger procedure than early stabilization would have been.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
At our Michigan clinic, Lisfranc injuries are evaluated with standing (weight-bearing) X-rays of both feet, stress views under fluoroscopy when needed, and MRI to assess ligament integrity. Stable injuries without diastasis are managed non-surgically with cast immobilization and non-weight-bearing for 6 to 8 weeks. Unstable injuries go directly to ORIF. We coordinate with sports medicine and orthopedics as needed for complex cases. The goal is restoring midfoot stability, protecting articular cartilage, and returning patients to full activity safely. No referral is needed for initial evaluation.
