Tarsal Tunnel Syndrome (TTS) is a condition in which the posterior tibial nerve or its branches become compressed within the tarsal tunnel, a narrow passageway located on the inner side of the ankle.

The tarsal tunnel is formed by:

• The bones of the ankle and foot
• The flexor retinaculum (a strong band of connective tissue)

Several important structures pass through this tunnel, including:

• Posterior tibial nerve
• Posterior tibial artery and vein
• Flexor tendons of the foot

When pressure increases within the tunnel, the tibial nerve becomes compressed, leading to pain, altered sensation, and weakness in the foot.

Tarsal Tunnel Syndrome is often compared to Carpal Tunnel Syndrome of the wrist because both involve nerve entrapment within a confined space.

The condition may develop gradually or suddenly and can significantly interfere with walking, standing, sports, and daily activities.

If left untreated, prolonged nerve compression may lead to chronic pain, muscle weakness, and permanent nerve dysfunction.

At Magnum Physiotherapy, our evidence-based treatment programs focus on reducing nerve irritation, correcting biomechanical factors, and restoring optimal foot function.

Common Symptoms

• Burning pain in the foot or ankle
• Tingling or pins-and-needles sensation
• Numbness in the sole of the foot
• Pain radiating into the toes
• Symptoms worsening with prolonged standing or walking
• Night pain or discomfort
• Foot weakness
• Reduced balance
• Increased symptoms during exercise
• Relief with rest in some cases

Causes & Risk Factors

Mechanical Causes

• Flat feet (Pes Planus)
• Overpronation
• Foot deformities
• Ankle instability

Space-Occupying Lesions

• Ganglion cysts
• Lipomas
• Varicose veins
• Bone spurs

Trauma-Related Causes

• Ankle sprains
• Fractures
• Scar tissue formation
• Previous surgery

Medical Conditions

• Diabetes mellitus
• Rheumatoid arthritis
• Inflammatory disorders
• Peripheral edema

Risk Factors

• Athletes and runners
• Occupations requiring prolonged standing
• Poor footwear
• Obesity

Anatomy Involved

The posterior tibial nerve divides into:

• Medial plantar nerve
• Lateral plantar nerve
• Calcaneal branches

Compression may affect one or multiple branches, resulting in varying symptom patterns.

Conditions Associated with Tarsal Tunnel Syndrome

• Plantar Fasciitis
• Posterior Tibial Tendon Dysfunction (PTTD)
• Flat Feet (Pes Planus)
• Ankle Instability
• Peripheral Neuropathy
• Diabetes Mellitus
• Varicose Veins

Diagnosis

At Magnum Physiotherapy, we conduct a comprehensive assessment to determine the cause and severity of nerve compression.

The evaluation may include:

• Detailed medical history
• Neurological examination
• Sensory testing
• Muscle strength assessment
• Foot posture evaluation
• Gait analysis
• Tinel’s Sign over the tarsal tunnel
• Functional movement assessment
• Review of imaging studies if available

Additional investigations may include:

• Nerve Conduction Studies (NCS)
• Electromyography (EMG)
• Ultrasound
• MRI scans

Benefits of Physiotherapy for Tarsal Tunnel Syndrome

• Reduces pain and nerve irritation
• Improves nerve mobility
• Enhances foot strength and stability
• Corrects abnormal biomechanics
• Improves walking ability
• Reduces numbness and tingling
• Prevents progression of nerve damage
• Supports return to sports and activities
• Improves balance and function
• Enhances quality of life

When Is Surgery Needed?

Surgery may be considered when:

• Conservative treatment fails
• Significant nerve compression persists
• Space-occupying lesions are present
• Progressive neurological deficits develop

Post-surgical physiotherapy is essential for restoring mobility and function.

Recovery & Prognosis

Recovery depends on:

• Duration of symptoms
• Severity of nerve compression
• Underlying cause
• Adherence to rehabilitation

Early diagnosis and treatment significantly improve outcomes and reduce the risk of permanent nerve damage.
