Quick Answer:
Quick Answer: Lisfranc injury refers to fracture-dislocation at the tarsometatarsal (TMT) joint complex — the articulation between the midfoot bones and metatarsal bases. These injuries span a spectrum: ligamentous Lisfranc sprain (subtle instability, no fracture), purely ligamentous dislocation, fracture-dislocation (fracture at the base of 2nd metatarsal — pathognomonic), and crush/high-energy multiplane dislocation. The key diagnostic challenge: subtle Lisfranc injuries are frequently missed on initial X-rays. Weight-bearing X-rays are mandatory — non-weight-bearing views miss the instability. CT scan identifies associated fractures. Stable injuries: 6 weeks non-weight-bearing cast. Unstable injuries: ORIF with screw fixation or primary arthrodesis of the medial TMT joints. Missed Lisfranc injury leads to painful post-traumatic arthritis requiring salvage arthrodesis.
The Lisfranc injury — fracture-dislocation at the tarsometatarsal joint complex — is one of the most commonly missed significant foot injuries in emergency medicine. The mechanism is often seemingly minor (stepping off a curb, a low-energy fall), yet the underlying instability can produce permanent disability from post-traumatic arthritis if not recognized and appropriately treated. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki provides accurate diagnosis and definitive surgical treatment for Lisfranc injuries in Michigan patients.
Why Lisfranc Injuries Are Missed
Lisfranc injuries are missed because the initial emergency room X-rays are taken non-weight-bearing — and the instability may not be visible without the patient’s body weight loading the midfoot. The key radiographic finding — a gap of >2mm between the base of the 1st and 2nd metatarsals on weight-bearing X-ray — disappears when the patient lies on the table and the joints reduce. The fleck sign — a small avulsion fracture at the base of the 2nd metatarsal or the medial cuneiform insertion of the Lisfranc ligament — is pathognomonic but subtle. Any patient with midfoot pain after trauma should have weight-bearing X-rays of both feet for comparison. CT scan identifies associated fracture patterns and preoperative planning. MRI detects purely ligamentous Lisfranc injuries in the absence of fracture.
Lisfranc Injury Classification and Treatment
Stable Lisfranc sprain: Intact Lisfranc ligament complex, no instability on stress views — 6 weeks non-weight-bearing in a CAM boot or short leg cast, progressive weight-bearing thereafter. Full return to activity in 3-4 months. Unstable ligamentous Lisfranc: Disrupted Lisfranc ligament with TMT joint instability and no fracture — surgical stabilization required: ORIF with transarticular screws across the 1st-2nd and 2nd-3rd TMT joints, or primary arthrodesis. Lisfranc fracture-dislocation: The most common pattern — fracture at the base of 2nd metatarsal with TMT joint disruption. ORIF with lag screws and/or bridge plating restores anatomy. Primary arthrodesis: For the medial TMT joints (1st, 2nd, 3rd) — fusion at the time of injury produces equivalent outcomes to ORIF with lower reoperation rates in several studies. The 4th and 5th TMT joints are mobile and should not be fused. High-energy crush injuries: Multiplane instability, significant soft tissue damage — staged treatment (temporary spanning external fixation until swelling resolves, then definitive fixation).
Recovery and Long-Term Outcomes
Lisfranc surgical recovery: 6-8 weeks non-weight-bearing post-operatively, then progressive weight-bearing in a CAM boot. Return to athletic activities at 4-6 months for ORIF, 6-12 months for arthrodesis. ORIF hardware is often removed at 4-6 months to restore residual TMT joint motion. Even with optimal treatment, post-traumatic arthritis develops in a significant percentage of patients — particularly following high-energy injuries with cartilage damage. Patients must understand this risk. Arthritic progression requires secondary arthrodesis of the affected TMT joints — an excellent salvage procedure with reliable pain relief.

✅ Pros / Benefits
- Weight-bearing X-ray diagnosis catches subtle Lisfranc instability missed on non-weight-bearing films
- ORIF restores anatomy and prevents post-traumatic arthritis progression in acute injuries
- Primary arthrodesis of medial TMT joints provides reliable outcomes with lower reoperation rates
- Prompt diagnosis and treatment prevents the disability of chronic post-traumatic midfoot arthritis
❌ Cons / Risks
- Even optimal treatment carries significant risk of post-traumatic TMT arthritis — particularly in high-energy injuries
- ORIF hardware removal is often required as a second procedure at 4-6 months
- Return to high-level athletic activity requires 6-12 months — longer than most midfoot injuries
Dr. Tom Biernacki’s Recommendation
Lisfranc injuries are a perfect example of why the emergency room X-ray is not the end of the diagnostic process for midfoot pain after trauma. I see patients who were told their X-rays were normal in the ER, walked on the injury for weeks, and present with a symptomatic midfoot instability that is now chronic. The question I always ask: were those weight-bearing X-rays? If not, we need to repeat them. A missed Lisfranc injury that gets treated as a sprain and bears weight becomes a painful midfoot arthritis case that requires salvage arthrodesis — a completely avoidable outcome with prompt accurate diagnosis.

Frequently Asked Questions
What is a Lisfranc injury?
A Lisfranc injury is a fracture-dislocation or ligamentous disruption at the tarsometatarsal (TMT) joint complex — the articulation where the five metatarsals meet the midfoot (cuneiform and cuboid bones). The Lisfranc ligament connects the base of the 2nd metatarsal to the medial cuneiform and is the key stabilizer of this complex. Lisfranc injuries range from subtle ligamentous sprains to severe fracture-dislocations with multiple broken bones. They are named after Jacques Lisfranc de St. Martin, a French surgeon who described midfoot amputations in cavalry soldiers who fell from horses with their feet caught in stirrups.
How is a Lisfranc injury diagnosed?
Lisfranc injury diagnosis requires weight-bearing X-rays of both feet — non-weight-bearing views frequently miss the instability because the joint reduces when unloaded. Key X-ray findings: diastasis (gap) >2mm between the 1st and 2nd metatarsal bases, malalignment of the 2nd metatarsal base with the middle cuneiform, and the fleck sign (avulsion fracture at the Lisfranc ligament insertion). CT scan is obtained for fracture characterization and surgical planning. MRI detects purely ligamentous injuries without fracture. Any midfoot pain after trauma warrants weight-bearing X-rays — the injury is too commonly missed on standard emergency views.
Do all Lisfranc injuries require surgery?
No — stable Lisfranc injuries with an intact ligament complex and no instability on stress X-rays can be treated non-operatively with 6 weeks non-weight-bearing followed by progressive rehabilitation. However, unstable injuries — defined as >2mm diastasis on weight-bearing or stress X-rays, or any fracture-dislocation — require surgical stabilization. Walking on an unstable Lisfranc injury accelerates post-traumatic arthritis and produces chronic midfoot pain. The threshold for surgery in Lisfranc injury is lower than for many other foot injuries because the consequences of undertreating are severe.
What is the recovery from Lisfranc surgery?
Lisfranc surgical recovery follows a standard sequence: strict non-weight-bearing for 6-8 weeks post-operatively (crutches or knee scooter), followed by progressive weight-bearing in a CAM boot, then transition to supportive footwear. Physical therapy begins with range-of-motion exercises and progresses to strengthening and gait training. ORIF hardware (screws) is typically removed at 4-6 months to restore residual TMT joint motion. Return to office work at 3-4 months; return to athletic activities at 6-12 months depending on injury severity and procedure. Custom orthotics with midfoot support are often recommended long-term.

When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
What is Stress fracture?
Stress fracture is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of stress fracture include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of stress fracture respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from stress fracture varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
