Tarsal Coalition: Causes, Diagnosis, and When Surgery Is Needed
Tarsal Coalition: When Foot Bones Fuse Together
Tarsal coalition is an abnormal connection between two or more of the tarsal bones — the bones of the hindfoot and midfoot. This connection can be bony (synostosis), cartilaginous (synchondrosis), or fibrous (syndesmosis), and it restricts normal motion between the affected bones. Coalition is congenital — present from birth — but symptoms typically do not emerge until adolescence when the bridge ossifies and restricts motion that the growing skeleton previously allowed.
Most Common Types
Calcaneonavicular coalition is the most common type, occurring between the calcaneus and navicular on the outer side of the midfoot. It is best visualized on a 45-degree oblique X-ray view and clearly seen on CT or MRI. Talocalcaneal coalition — fusion between the talus and calcaneus at the middle subtalar facet — is the second most common type and is notoriously difficult to see on plain X-rays, frequently requiring CT for definitive diagnosis. Both types restrict subtalar motion — the inversion-eversion motion of the hindfoot — producing a rigid, painful flat foot.
Who Is Affected?
Coalition affects an estimated 1 to 2 percent of the population, though many cases are never symptomatic. Males are more commonly affected than females. Coalition is bilateral in approximately 50 percent of calcaneonavicular and 25 percent of talocalcaneal cases. Symptoms most commonly emerge between ages 8 and 16 as the cartilaginous coalition ossifies. A family history of coalition is found in many cases, suggesting an autosomal dominant inheritance pattern with variable penetrance.
Symptoms and Presentation
The typical presentation is an adolescent with activity-related foot and ankle pain, a rigid flat foot, limited subtalar inversion-eversion on examination, and recurrent ankle sprains. The limited hindfoot motion means the normal shock absorption of the subtalar joint is absent, transmitting excessive force to the ankle and surrounding structures. Peroneal muscle spasm — causing a “peroneal spastic flat foot” — is characteristic of symptomatic talocalcaneal coalition. In calcaneonavicular coalition, the spasm may be less pronounced but subtalar restriction is equally present.
Diagnosis
Weight-bearing X-rays in multiple projections — AP, lateral, and 45-degree oblique — are the first imaging step. The “anteater sign” on lateral X-ray (an elongated anterior process of the calcaneus extending toward the navicular) suggests calcaneonavicular coalition. CT scan provides the most accurate assessment of the size and extent of bony coalition. MRI identifies fibrous and cartilaginous coalitions that may not be visible on CT and evaluates surrounding joint surfaces for secondary arthritic change.
Conservative Treatment
Mild symptoms in adolescents often respond to activity modification, custom orthotics that support the arch and reduce stress on the coalition, and physical therapy. Corticosteroid injection into the affected joint space reduces acute inflammatory pain. Immobilization in a walking boot for 4 to 6 weeks during acute flares reduces synovitis. Conservative management is typically tried for 3 to 6 months before surgical consideration in adolescents.
Surgical Treatment
Resection of the coalition — surgically removing the abnormal bone bridge — restores motion and eliminates the impingement-related pain in appropriately selected cases. For calcaneonavicular coalition, resection with fat graft interposition has excellent outcomes in patients without secondary hindfoot arthritis. Talocalcaneal coalition resection has good results when the coalition involves less than 50 percent of the posterior facet and secondary subtalar arthritis is absent. When significant arthritis is present, subtalar fusion is required rather than resection.

What is Foot pain?
Foot pain 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 foot pain 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 foot pain 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 foot pain 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.

Frequently Asked Questions
When should I see a podiatrist?
See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.
What is the difference between a podiatrist and an orthopedic surgeon?
Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.
How do I know if my foot pain is serious?
Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.
Can foot problems cause back and knee pain?
Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.
Are orthotics worth it?
For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.
How do I choose the right running shoes?
Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.
What is the difference between a sprain and a fracture?
A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.
How do I prevent foot and ankle injuries?
The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.
