Posterior Tarsal Tunnel Syndrome

Aka: Posterior Tarsal Tunnel Syndrome, Tarsal Tunnel Syndrome, Tarsal Tunnel, Tibial Neuropathy, Posterior Tibial Nerve Entrapment
  1. Anatomy (See Ankle Anatomy)
    1. Posterior Tibial Nerve
      1. Behind medial malleolus and under flexor Retinaculum
    2. Flexor Retinaculum
      1. Arises from medial malleolus
      2. Insertion into medial Calcaneus
      3. Encases
        1. Posterior tibial nerve
        2. Tibialis posterior tendon
        3. Flexor digitorum longus tendon
        4. Flexor hallucis longus tendon
        5. Posterior tibial artery
        6. Posterior tibial vein
  2. Epidemiology
    1. Uncommon
  3. Pathophysiology
    1. Posterior Tibial Nerve compressed in flexor Retinaculum
  4. Associated Conditions
    1. Phlebitis
    2. Rheumatoid Arthritis
    3. Pes Planus
    4. Foot Fracture
    5. Foot traction injury
    6. Heel or foot deformity
    7. Foot mass lesion
  5. Symptoms
    1. Burning, numbness, or tingling sensation
      1. Starts at plantar heel
      2. May radiate to distal sole of foot to toes
      3. May radiate to calf
    2. Provocative
      1. Worse with ambulation
      2. Worse at night
  6. Signs
    1. Sensory loss in posterior tibial nerve distribution
    2. Motor function usually intact
      1. Intrinsic Muscle Weakness may be present
    3. Provocative maneuvers may elicit symptoms
      1. Tinel's sign
        1. Percussion over Tarsal Tunnel (Flexor Retinaculum)
        2. Identify posterior tibial tendon
          1. Lies behind medial malleolus
          2. Find tendon by inverting foot against resistance
        3. Posterior tibial nerve lies behind tibial tendon
      2. Stretch, compress posterior tibial nerve
        1. Simultaneous dorsiflexion and eversion of foot
  7. Differential Diagnosis
    1. Complex Regional Pain Syndrome
    2. Plantar Fasciitis
    3. Diabetic Neuropathy
    4. Lumbar Disc Disease (Lumbosacral Radiculopathy)
    5. Peripheral Neuropathy
    6. Posterior tibial dysfunction
    7. Exertional Compartment Syndrome
  8. Management
    1. Stretching Program
    2. Medial Heel wedge or Heel Seat
      1. Inverts heel
      2. Removes traction from tibial nerve
    3. Orthotics to correct foot Posture (e.g. Pes Planus)
    4. Tarsal Tunnel Injection
    5. Surgical release of entrapment
      1. Indicated for persistent symptoms

Tarsal Tunnel Syndrome (C0039319)

Definition (NCI) A syndrome resulting from the entrapment and compression of the tibial nerve. Signs and symptoms include burning sensation, tingling, and pain in the foot sole.
Definition (MSH) Entrapment of the distal branches of the posterior TIBIAL NERVE (which divides into the medial plantar, lateral plantar, and calcanial nerves) in the tarsal tunnel, which lies posterior to the internal malleolus and beneath the retinaculum of the flexor muscles of the foot. Symptoms include ankle pain radiating into the foot which tends to be aggravated by walking. Examination may reveal Tinel's sign (radiating pain following nerve percussion) over the tibial nerve at the ankle, weakness and atrophy of the small foot muscles, or loss of sensation in the foot.
