| Classification | Description | Stability | X-ray Finding | Treatment | Prognosis |
|---|---|---|---|---|---|
| Sprain (partial ligament) | Lisfranc ligament partially torn; no displacement | Stable (no diastasis on weight-bearing X-ray) | Normal or minimal widening <2mm between 1st and 2nd metatarsal bases | NWB cast 6-8 weeks; transition to boot; orthotic support | Good; most return to full activity by 4-6 months |
| Partial Dislocation (Myerson A-C) | Partial displacement of 1-3 metatarsals; partial ligament complex tear | Unstable; positive weight-bearing diastasis | >2mm diastasis between 1st/2nd MT base; fleck sign (avulsion fragment) | ORIF with screws or bridge plating; NWB 6-8 weeks post-op | Good with anatomic reduction; worse if treated non-surgically when unstable |
| Total Dislocation (Myerson D) | All 5 metatarsals displaced; complete Lisfranc complex disruption | Grossly unstable; deformity visible | Complete lateral shift of all metatarsals; dorsal displacement | Emergent ORIF; definitive fixation within 6-12 hours ideal to reduce swelling | Fair; highest risk of post-traumatic Lisfranc arthritis; arthrodesis may be needed at 1-2 years |
| Divergent Pattern | Medial and lateral column displace in opposite directions | Unstable | Medial column medial, lateral column lateral on AP view | ORIF; often requires primary fusion of medial column | Fair; highest rate of secondary arthrodesis |
| Purely Ligamentous | No bony fracture; pure soft tissue instability; often missed | Unstable on weight-bearing; may appear normal at rest | Normal NWB X-ray; diastasis only on weight-bearing views – KEY DIAGNOSTIC STEP | Surgical if diastasis >2mm on WB X-ray; non-surgical if stable on WB | Better with surgical stabilization; non-op purely ligamentous has high arthritis rate |
| Red Flag | Why It Matters | Action |
|---|---|---|
| Midfoot pain after twisting injury that doesn’t improve in 5-7 days | Purely ligamentous Lisfranc injuries look normal on standard NWB X-ray; delay causes missed diagnosis | Weight-bearing X-ray series (AP, oblique, lateral) – essential for diagnosis |
| Fleck sign on X-ray (small avulsion fragment) | Pathognomonic of Lisfranc ligament avulsion; virtually diagnostic even if no diastasis visible at rest | Treat as Lisfranc injury; obtain weight-bearing views and MRI |
| Diastasis >2mm between 1st and 2nd MT base on weight-bearing | Indicates ligamentous instability requiring surgical fixation regardless of fracture presence | Surgical referral; ORIF or primary arthrodesis depending on injury pattern |
| Inability to perform single-leg heel raise | Indicates midfoot instability significant enough to impair push-off mechanics | Evaluate for Lisfranc instability with weight-bearing X-ray |
| Plantar ecchymosis (bruising on bottom of foot) | Plantar bruising after midfoot trauma is highly specific for Lisfranc injury vs simple sprain | High clinical suspicion; weight-bearing X-rays + MRI regardless of initial X-ray appearance |

The most important clinical decision with Lisfranc Injury Foot isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
What Is the Lisfranc Joint and How Is It Injured?
The Lisfranc joint complex — named for Jacques Lisfranc de St. Martin, a French surgeon who described amputations at this level in the Napoleonic Wars — is the articulation between the five metatarsals and the three cuneiforms and cuboid in the midfoot. This joint complex is held together by a network of ligaments, with the Lisfranc ligament (connecting the medial cuneiform to the second metatarsal base) serving as the keystone stabilizer of the entire midfoot arch. Injury to this complex produces one of the most commonly missed diagnoses in orthopedic emergency medicine.
Lisfranc injuries occur through two main mechanisms: high-energy trauma (motor vehicle accidents, falls from height, industrial crushing injuries) and low-energy indirect loading (a twisting fall with the foot plantarflexed — the classic stumble while stepping off a curb, or the equestrian injury of a foot caught in a stirrup during a fall). Football players are at particular risk for the indirect mechanism: the injury commonly occurs when a player falls with the foot planted in plantarflexion while another player lands on the heel, forcing the midfoot into hyperflexion.
The spectrum of Lisfranc injury ranges from isolated Lisfranc ligament sprain (without any bony injury or displacement) to complete ligamentous disruption with full dislocation of all five metatarsals from their cuneiform articulations. Because even subtle displacement of the second metatarsal from the medial cuneiform significantly alters midfoot mechanics, the distinction between a mild sprain and a displacement that requires surgery can be clinically challenging and requires careful imaging interpretation.
Why Lisfranc Injuries Are Commonly Missed
Lisfranc injuries are missed at initial evaluation in up to 40% of cases, making them one of the most frequently overlooked significant musculoskeletal injuries. The miss rate is attributable to several factors: the injury does not have a dramatic clinical appearance (significant swelling and bruising, but no obvious deformity in many cases), standard non-weight-bearing X-rays are often read as normal when subtle displacement is only visible on weight-bearing views, and emergency physicians may not have high index of suspicion for this specific injury pattern.
The diagnostic key that emergency physicians and primary care physicians sometimes miss: Lisfranc injury must be evaluated with weight-bearing X-rays. Non-weight-bearing X-rays are frequently normal even in surgically significant injuries because the midfoot is only displaced when loaded. The stress of weight-bearing separates the injured ligamentous complex and reveals the displacement at the Lisfranc joint. A standard ER X-ray taken with the patient lying on the gurney can appear normal, leading to discharge with a ‘foot sprain’ diagnosis and instructions to follow up if symptoms persist — during which time the patient walks on an unstable midfoot and potentially converts a ligamentous injury into a more complex problem.
MRI provides the most hands-on exam plus imaging when needed of Lisfranc ligament integrity and is the imaging modality of choice when X-rays are negative or equivocal but clinical suspicion for injury is high. CT scan better characterizes any bony injury and displacement. Dr. Tom Biernacki has a high clinical index of suspicion for Lisfranc injuries and routinely obtains weight-bearing X-rays and advanced imaging when the injury pattern suggests midfoot instability.
Treatment and Long-Term Outcomes After Lisfranc Injury
Treatment depends on the severity and stability of the injury. Purely ligamentous Lisfranc sprains without any instability on weight-bearing X-rays can be managed conservatively with non-weight-bearing cast immobilization for 6–8 weeks, followed by protected weight-bearing and physical therapy. However, this is the minority of Lisfranc injuries — most that present to podiatric or orthopedic evaluation have some degree of instability that requires surgical stabilization.
Surgical fixation — open reduction and internal fixation (ORIF) with screws, Kirschner wires, or bridge plates — restores the normal anatomical relationships at the Lisfranc joint and allows the ligaments to heal in a reduced position. Primary arthrodesis (fusion) of the Lisfranc joint complex may be performed for purely ligamentous injuries (without fracture) because the midfoot functions primarily as a rigid lever with minimal motion, making fusion biomechanically well-tolerated and associated with better long-term outcomes than ORIF for ligamentous injuries in some studies.
The long-term prognosis of Lisfranc injury is significant: even optimally treated injuries are associated with a high rate of post-traumatic midfoot arthritis, particularly at the tarsometatarsal joints. Athletes who sustain Lisfranc injuries often report persistent midfoot discomfort and stiffness that limits high-level sport participation. Early surgical intervention for unstable injuries — and accurate diagnosis in the first place — are the most important factors in optimizing long-term outcomes.

Dr. Tom Biernacki’s Recommendation
Lisfranc injuries are the injury I most dread patients missing — because delayed diagnosis turns what could be a manageable injury into a chronic midfoot arthritis problem. If you rolled your foot, have midfoot swelling and bruising, and your ER X-rays were ‘normal,’ please see a podiatrist or orthopedic surgeon for weight-bearing films before you conclude that it’s just a sprain. The stakes are too high to miss this one.

Frequently Asked Questions
How do you know if you have a Lisfranc injury?
Key features: midfoot pain and swelling after a twisting or crushing injury, pain with weight-bearing in the middle of the foot, and bruising on the plantar (bottom) aspect of the foot. Weight-bearing X-rays showing gap between the first and second metatarsal bases confirm the diagnosis.
Do all Lisfranc injuries require surgery?
No. Purely ligamentous Lisfranc sprains without instability may be managed conservatively. However, any injury with displacement on weight-bearing X-rays requires surgical stabilization for optimal outcomes.
How long is Lisfranc injury recovery?
Conservative treatment takes 3–4 months before walking normally. Surgical recovery typically involves 6–8 weeks non-weight-bearing followed by progressive weight-bearing and physical therapy. Full return to sport is typically 4–6 months post-operatively.
