Study Notes
TRS (Tarsal tunnel syndrome)
Definition:
- Tarsal tunnel syndrome (TRS) is a compression neuropathy of the posterior tibial nerve
- Also known as posterior tibial neuralgia or tibial nerve entrapment
Causes:
- Compression of the posterior tibial nerve as it passes through the tarsal tunnel
- Tarsal tunnel is a narrow passageway in the ankle that contains the posterior tibial nerve, tendons, and arteries
- Compression can occur due to:
- Anatomical abnormalities
- Overuse or repetitive strain
- Trauma or injury
- Space-occupying lesions (e.g., ganglion cysts, tumors)
Symptoms:
- Pain, numbness, or tingling in the ankle, foot, or toes
- Burning or shooting pain in the heel or arch of the foot
- Weakness or fatigue in the foot or ankle
- Numbness or tingling in the toes
- Difficulty walking or standing
Diagnosis:
- Physical examination and medical history
- Electromyography (EMG) and nerve conduction studies (NCS) to confirm nerve compression
- Imaging studies (e.g., MRI, CT) to rule out other conditions
Treatment:
- Conservative management:
- Rest and ice
- Orthotics or shoe modifications
- Physical therapy
- Medications (e.g., NSAIDs, corticosteroids)
- Surgical intervention:
- Decompression of the posterior tibial nerve
- Release of the tarsal tunnel
Prognosis:
- Good prognosis with early diagnosis and treatment
- Delayed or inadequate treatment can lead to chronic symptoms and permanent nerve damage
Tarsal Tunnel Syndrome (TRS)
- Tarsal tunnel syndrome is a compression neuropathy of the posterior tibial nerve.
- Also known as posterior tibial neuralgia or tibial nerve entrapment.
Causes of TRS
- Compression of the posterior tibial nerve as it passes through the tarsal tunnel.
- The tarsal tunnel is a narrow passageway in the ankle that contains the posterior tibial nerve, tendons, and arteries.
- Compression can occur due to anatomical abnormalities, overuse or repetitive strain, trauma or injury, and space-occupying lesions (e.g., ganglion cysts, tumors).
Symptoms of TRS
- Pain, numbness, or tingling in the ankle, foot, or toes.
- Burning or shooting pain in the heel or arch of the foot.
- Weakness or fatigue in the foot or ankle.
- Numbness or tingling in the toes.
- Difficulty walking or standing.
Diagnosis of TRS
- Physical examination and medical history.
- Electromyography (EMG) and nerve conduction studies (NCS) to confirm nerve compression.
- Imaging studies (e.g., MRI, CT) to rule out other conditions.
Treatment of TRS
- Conservative management: • Rest and ice. • Orthotics or shoe modifications. • Physical therapy. • Medications (e.g., NSAIDs, corticosteroids).
- Surgical intervention: • Decompression of the posterior tibial nerve. • Release of the tarsal tunnel.
Prognosis of TRS
- Good prognosis with early diagnosis and treatment.
- Delayed or inadequate treatment can lead to chronic symptoms and permanent nerve damage.
