Tarsal tunnel syndrome (TTS) is a compressive neuropathy of the posterior tibial nerve and its branches within the tarsal tunnel — the fibro-osseous canal posterior to the medial malleolus. TTS is frequently misdiagnosed as plantar fasciitis and remains one of the most challenging diagnoses in podiatric medicine, with electrodiagnostic studies negative in up to 40% of clinically diagnosed cases.
Anatomy of the Tarsal Tunnel
The tarsal tunnel is bounded medially by the flexor retinaculum (laciniate ligament), laterally by the medial wall of the calcaneus, and superiorly by the medial malleolus and talus. The posterior tibial nerve — accompanied by the posterior tibial artery and flexor tendons — divides within or just distal to the tunnel into three branches: the medial plantar nerve (innervating the medial forefoot), the lateral plantar nerve (innervating the lateral forefoot and intrinsic muscles), and the medial calcaneal nerve (innervating the medial heel). The site of compression determines the pattern of neurological symptoms.
Causes and Associated Conditions
Space-occupying lesions within the tarsal tunnel — ganglia, lipomas, varicose veins, accessory muscles (flexor digitorum accessorius longus), and os trigonum — account for 20–30% of TTS cases and are identified on MRI. Hindfoot valgus (flatfoot deformity) stretches the posterior tibial nerve over the medial malleolus with pronation and is a major biomechanical contributor to TTS in the flatfoot population. Post-traumatic fibrosis following ankle fracture or sprain, inflammatory tenosynovitis in rheumatoid arthritis, and space-occupying hematoma are additional etiologies.
Clinical Presentation and Diagnosis
Classic TTS presents with burning, tingling, and numbness along the plantar foot and toes, aggravated by prolonged standing and walking and often worse at night. The Tinel’s sign (reproduction of burning or tingling with percussion over the tarsal tunnel posterior to the medial malleolus) is present in 40–60% of cases. The dorsiflexion-eversion test (sustained maximum dorsiflexion and eversion for 10 seconds) reproduces symptoms in TTS with higher sensitivity. MRI is essential for identifying space-occupying lesions. Electrodiagnostic studies (nerve conduction velocity, electromyography) confirm axonal compromise but have significant false-negative rates in early or primarily demyelinating compression.
Conservative Treatment
Initial conservative management includes custom orthotics with medial arch support to reduce hindfoot valgus and neural stretch, activity modification, NSAID therapy, and ultrasound-guided corticosteroid injection around the posterior tibial nerve. Conservative management succeeds in 50–60% of patients with flexible etiology but has poor results when a space-occupying lesion is identified. Response to diagnostic ultrasound-guided nerve block with local anesthetic confirms TTS and predicts a positive surgical outcome.
Surgical Tarsal Tunnel Release
Surgical release of the flexor retinaculum decompresses the posterior tibial nerve and its branches, addressing all three plantar nerve divisions including the medial calcaneal branch. When a space-occupying lesion is identified, simultaneous excision is performed. Outcomes are best when a discrete lesion is identified and worst in idiopathic cases with long-standing symptoms — reflecting why we early diagnosis and intervention before irreversible axonal damage. Recovery involves 4–6 weeks of protected weight bearing followed by progressive return to activity.
Tarsal Tunnel Evaluation at Balance Foot & Ankle
Dr. Biernacki at Balance Foot & Ankle evaluates tarsal tunnel syndrome with on-site diagnostic ultrasound, ultrasound-guided diagnostic nerve block, and MRI coordination for lesion identification at the first visit. Conservative management and surgical tarsal tunnel release are both available within the practice. Call (810) 206-1402 for a same-week evaluation of burning plantar foot pain.

Not every case of tarsal tunnel syndrome is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.
| Condition | How It Differs |
|---|---|
| Plantar fasciitis | Sharp morning heel pain at the medial calcaneal tubercle, NOT numbness or shooting pain into the toes. |
| Diabetic peripheral neuropathy | Bilateral stocking-glove distribution, progressive, affects toes first — NOT reproduced by Tinel’s at medial ankle. |
| S1 radiculopathy | Pain originates in low back, follows S1 dermatome, positive straight-leg raise. |

In Our Clinic: What We See
Clinical perspective from Dr. Tom Biernacki, DPM — Balance Foot & Ankle, Howell & Bloomfield Hills, MI:
In our Balance Foot & Ankle clinic, tarsal tunnel patients typically describe burning, tingling, or shock-like pain on the bottom of the foot, often worst at night. Unlike plantar fasciitis (sharp morning pain at the heel), tarsal tunnel causes neuropathic symptoms extending into the arch and toes. The classic exam finding is a positive Tinel’s sign over the posterior tibial nerve at the medial ankle. We assess for space-occupying lesions (ganglion, varicosity, accessory muscle) with ultrasound or MRI. Conservative management with orthotics, anti-inflammatories, and night splints resolves most cases; refractory cases may need surgical release.

When to See a Podiatrist
Foot and ankle surgery in 2026 is dramatically different than a decade ago — most procedures are now minimally-invasive, outpatient, and allow weight-bearing within days. Balance Foot & Ankle surgeons have performed 3,000+ foot/ankle surgeries with modern techniques. If another surgeon has recommended a traditional open procedure, a second opinion may reveal a faster, less-invasive option.
