What Is a Lisfranc Injury?

A Lisfranc injury is a fracture, dislocation, or ligamentous disruption of the tarsometatarsal (TMT) joint complex — the junction between the midfoot bones (cuneiforms and cuboid) and the metatarsal bases. These injuries range from subtle ligament sprains to complex fracture-dislocations with significant displacement. They are one of the most frequently missed serious foot injuries in emergency medicine — approximately 20–40% of Lisfranc injuries are initially misdiagnosed as “foot sprains,” leading to delayed treatment and permanent midfoot instability. At Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan, Dr. Tom Biernacki, DPM accurately diagnoses and manages Lisfranc injuries. Call (810) 206-1402.

How Lisfranc Injuries Happen

Lisfranc injuries occur through two mechanisms: high-energy trauma (motor vehicle accidents, industrial crush injuries — produces complex fracture-dislocations requiring surgery) and low-energy indirect mechanisms (stepping in a hole while running, a football cleat catching the turf, a horse-riding fall with foot in stirrup — produces subtle ligamentous injuries that are easily missed). In our clinic, the most diagnostically challenging cases are the low-energy indirect injuries — a runner who “twisted” their foot, X-rays show no obvious fracture, and they’re sent home with “foot sprain.” The key is recognizing the mechanism and ordering weight-bearing X-rays or MRI.

The Diagnostic Keys — Why Routine X-Rays Miss Lisfranc Injuries

Non-weight-bearing ankle and foot X-rays taken in the ER frequently appear normal in subtle Lisfranc injuries. The critical diagnostic view is a weight-bearing AP X-ray of the foot — the compressive force of weight-bearing opens the midfoot instability that’s invisible at rest. The classic radiographic sign: >2mm widening between the first and second metatarsal bases, or loss of alignment between the medial border of the second metatarsal and the medial border of the intermediate cuneiform. When X-ray is equivocal, MRI is the gold standard for identifying the degree of ligamentous disruption. CT scan is used for surgical planning in confirmed injuries.

Classification and Treatment Decision

Lisfranc injuries are classified as stable (intact Lisfranc ligament, no displacement — rare) or unstable (disrupted ligament ± fracture, with displacement on stress views). Stable injuries without displacement can be treated conservatively with strict non-weight-bearing for 6–8 weeks in a cast or CAM boot, followed by gradual weight-bearing at 8–10 weeks. Unstable injuries with any displacement (>2mm on weight-bearing X-ray) require surgical stabilization — either open reduction and internal fixation (ORIF) with screws/plates, or primary arthrodesis (fusion) for injuries with significant articular damage. Attempting to treat an unstable Lisfranc injury conservatively leads to progressive midfoot collapse, early arthritis, and a poor functional outcome.

Recovery Timeline

Conservative treatment: 6–8 weeks non-weight-bearing, 8–10 weeks partial weight-bearing in a boot, return to light activity at 4–6 months. Surgical treatment (ORIF): non-weight-bearing 8–10 weeks, gradual return to weight-bearing 10–14 weeks, return to sport 6–9 months. Hardware removal is typically performed at 3–4 months post-operatively (screws crossing the mobile TMT joints need removal to prevent breakage during return to activity). Primary arthrodesis cases: longer fusion healing time, 4–6 months before full activity.

Long-Term Outcomes and Post-Traumatic Arthritis

Even with optimal treatment, post-traumatic midfoot arthritis develops in a significant proportion of Lisfranc injuries — particularly those that were displaced, involved significant articular comminution, or were treated with delay. Symptoms include: midfoot aching with prolonged activity; loss of arch height over time; and pain specifically at the TMT joints. Management options include custom orthotics with a rigid arch extension, rocker-bottom shoe modifications, cortisone injections, and ultimately TMT arthrodesis for refractory cases. Early accurate diagnosis and treatment produces the best long-term outcomes.

Red Flags — Don’t Miss a Lisfranc

Seek urgent evaluation for: midfoot pain and swelling after any significant foot twisting mechanism, even if “X-rays were negative”; inability to bear weight after a midfoot injury; bruising specifically on the plantar (bottom) surface of the midfoot — plantar ecchymosis is pathognomonic for Lisfranc injury; or pain specifically at the TMT joints (between the midfoot and metatarsals). A “negative X-ray” does not rule out a Lisfranc injury — request weight-bearing views or MRI.
