Mechanisms of Lisfranc Injury
Lisfranc injuries occur by two primary mechanisms: direct trauma—a crushing force to the midfoot (often from a motor vehicle accident, heavy object dropping on the foot, or industrial injury) that produces high-energy fracture-dislocations; and indirect trauma—a twisting or rotational force applied to the plantar-flexed foot, more common in sports (football, equestrian falls, soccer) and low-energy incidents (simply missing a step and landing on a plantarflexed foot).
The indirect mechanism produces the ligamentous “sprain-type” Lisfranc injury that is most commonly missed—because the patient walks in with what appears to be a midfoot sprain, plain X-rays appear near-normal, and the injury is discharged without stress imaging to reveal the instability. Many athletes have returned to sport with an unstable Lisfranc injury, causing progressive arthritis that might have been avoided with early surgical stabilization.
Recognizing the Missed Diagnosis
Clinical red flags for Lisfranc injury include: midfoot pain after trauma (especially any plantar-flexion/rotation mechanism), inability to bear weight on the medial forefoot, plantar ecchymosis (bruising on the bottom of the foot, particularly in the midfoot region—virtually pathognomonic), and tenderness to palpation and stress testing at the first and second metatarsal base junction.

The classic radiographic finding on weight-bearing AP foot X-rays is diastasis (widening) between the first and second metatarsal bases—a gap greater than 2mm indicates Lisfranc ligament disruption. Non-weight-bearing X-rays may appear completely normal in ligamentous injuries. Weight-bearing X-rays are essential—patients who are evaluated only with non-weight-bearing films in the emergency department frequently leave with an undiagnosed unstable Lisfranc injury.
CT scan characterizes fracture anatomy comprehensively. MRI confirms ligamentous injury patterns—particularly valuable in differentiating stable from unstable ligamentous injuries when plain films are equivocal and surgical versus non-operative management is being decided.
Classification: Stable vs. Unstable
The most critical clinical decision in Lisfranc management is determining stability. Stable injuries have intact or minimally disrupted ligaments without diastasis—these are treated non-operatively with non-weight-bearing cast immobilization for 6–8 weeks. Unstable injuries—any fracture-dislocation, diastasis greater than 2mm, or ligamentous disruption producing midfoot instability on stress examination—require surgical stabilization to prevent progressive arthritis.
Non-Surgical Treatment of Stable Lisfranc Injuries
Stable, purely ligamentous Lisfranc injuries without diastasis are managed in a non-weight-bearing short-leg cast for 6–8 weeks. Transition to a walking boot follows, with progressive weight-bearing over 4–6 weeks. Physical therapy restores strength and proprioception before return to sport—typically at 12–16 weeks from injury. Serial imaging ensures no late displacement occurs during the healing period.
Surgical Treatment: ORIF and Primary Arthrodesis
Unstable Lisfranc injuries are treated surgically. Two approaches are used depending on injury pattern:
Open reduction internal fixation (ORIF) with screws or plates restores and maintains anatomic reduction of the tarsometatarsal joints. Hardware is typically removed at 4–6 months. The debate between screw fixation and flexible fixation (bridge plating) is ongoing—current evidence suggests both are effective for appropriate fracture patterns.
Primary arthrodesis (fusion) of the medial three tarsometatarsal joints (first, second, third) is increasingly favored for purely ligamentous Lisfranc injuries—several randomized controlled trials have shown superior long-term outcomes versus ORIF for ligamentous injuries specifically, with lower re-operation rates and better patient-reported outcomes at 5-year follow-up. For fracture-dislocation patterns, the choice between ORIF and primary fusion remains surgeon and injury dependent.
Recovery from Lisfranc surgery involves 6–8 weeks non-weight-bearing, progressive rehabilitation, and return to sport at 6–12 months depending on the extent of injury and surgical technique.

- Even well-treated Lisfranc injuries may develop some degree of midfoot arthritis over years
Dr. Tom Biernacki’s Recommendation
Lisfranc is the injury I think about when an athlete comes in after a foot injury and says ‘the ER said it was just a sprain.’ I go straight to weight-bearing X-rays. If there’s any hint of diastasis at the first-second metatarsal base junction, or if there’s plantar ecchymosis, I order MRI immediately. Missing this diagnosis is one of the most consequential errors in foot and ankle care—the athlete goes back to sport, loads the unstable midfoot, develops progressive arthritis, and ends up needing a fusion that was preventable. Early diagnosis and appropriate management—whether that’s a proper cast protocol for stable injuries or surgery for unstable ones—gives patients the best chance at a full, lasting recovery.

Frequently Asked Questions
How do I know if I have a Lisfranc injury?
Warning signs after a midfoot injury include: inability to bear full weight on the foot, midfoot pain (specifically in the arch area at the base of the toes), bruising on the bottom of the foot (plantar ecchymosis), and swelling across the top of the midfoot. Lisfranc injury is frequently missed on emergency X-rays if weight-bearing films aren’t obtained—if you’ve been told you have a midfoot sprain and haven’t improved in 1–2 weeks, seek specialist evaluation.
Is Lisfranc injury always surgical?
No—stable Lisfranc injuries (no diastasis, no fracture-dislocation) are managed non-operatively with 6–8 weeks of non-weight-bearing cast immobilization. Unstable injuries require surgery. The decision between operative and non-operative treatment requires careful clinical and imaging assessment—weight-bearing X-rays are essential.
How long does Lisfranc injury recovery take?
Stable non-operative cases: 6–8 weeks cast, then boot, return to sport at 12–16 weeks. Surgical cases: 6–8 weeks non-weight-bearing, then progressive rehabilitation, return to sport at 6–12 months depending on the extent of injury and technique used.
Can I return to sports after a Lisfranc injury?
Yes—most patients return to full sport after appropriate treatment of Lisfranc injury. Return timing depends on injury severity and treatment. Ligamentous injuries treated non-operatively return at 3–4 months. Surgical cases typically return at 6–12 months. Some patients develop midfoot stiffness from arthritis that affects high-impact cutting activities long-term.

Quick Answer:
Quick Answer: Lisfranc injury refers to fracture-dislocation or ligamentous disruption at the tarsometatarsal (Lisfranc) joint complex in the midfoot. It ranges from purely ligamentous (sprain type) to severe fracture-dislocations. It is commonly missed on initial emergency room evaluation—sometimes for weeks—because standard X-rays may appear near-normal. Dr. Biernacki treats Lisfranc injuries with non-weight-bearing cast management for purely ligamentous injuries and surgical internal fixation or primary arthrodesis for unstable fracture-dislocations.
Lisfranc injury is the foot trauma equivalent of a missed diagnosis—one of the most frequently overlooked injuries in emergency medicine. The Lisfranc joint complex refers to the articulation between the tarsal bones (cuneiform and cuboid) and the bases of all five metatarsals. When this critical midfoot stabilizer is disrupted by trauma, the consequences of delayed or missed diagnosis include chronic midfoot instability, post-traumatic arthritis, and permanent functional loss. Understanding Lisfranc injury is essential for athletes, active adults, and anyone who has sustained a midfoot injury.
The Lisfranc Joint: Anatomy and Stability
The Lisfranc joint complex is stabilized by a system of bony and ligamentous architecture that creates a Roman arch-like configuration: the second metatarsal base is recessed proximally, locked between the medial and lateral cuneiforms in a mortise joint that provides inherent bony stability. The Lisfranc ligament proper—a stout ligament running from the medial cuneiform to the second metatarsal base—is the primary stabilizer of the complex. Additional transverse and dorsal ligamentous connections between metatarsal bases and cuneiform provide secondary stability.
Critically, the first and second metatarsal bases have no direct intermetatarsal ligament between them—meaning the Lisfranc ligament is the only structure directly connecting these bones. When the Lisfranc ligament fails, the second metatarsal loses its medial tether and the entire medial column can dorsally subluxate (shift upward) with weight-bearing.
Mechanisms of Lisfranc Injury
Lisfranc injuries occur by two primary mechanisms: direct trauma—a crushing force to the midfoot (often from a motor vehicle accident, heavy object dropping on the foot, or industrial injury) that produces high-energy fracture-dislocations; and indirect trauma—a twisting or rotational force applied to the plantar-flexed foot, more common in sports (football, equestrian falls, soccer) and low-energy incidents (simply missing a step and landing on a plantarflexed foot).
