II. Epidemiology

  1. Most common Entrapment Neuropathy of the arm
    1. Prevalence: 3% of U.S. general population
    2. Incidence: 3.8 per 1000 person-years (increasing with age)
  2. Women outnumber men affected by 3 fold
  3. Bilateral in 50% of cases
  4. Associated with workplace repetitive hand activities
  5. Hand Paresthesias occur in 30% of computer users
    1. Only 10% of these meet criteria for Carpal Tunnel
    2. Only 3.5% of these have abnormal EMGs
    3. Stevens (2001) Neurology 56:1568-70 [PubMed]

III. Pathophysiology

  1. Compression of Median Nerve
    1. Occurs between transverse carpal ligament and underlying Carpal Bones
    2. Median Nerve adjacent to 9 flexor tendons whose synovial lining may become inflamed and enlarged
  2. Sensory deficits predominate
    1. Motor Nerves are much less susceptible than Sensory Nerves to compression

IV. Risk Factors: General

  1. Repetitive motion of hand and wrist
    1. Most common cause, and typically work related
    2. More common if significant force applied or hand-operated vibratory tool
  2. Local wrist or Hand Trauma
  3. Many predisposing conditions (see below)

V. Risk Factors: Predisposing Medical Conditions

  1. Obesity
  2. Hypothyroidism
  3. Diabetes Mellitus
  4. Acromegaly
  5. Rheumatoid Arthritis
  6. Gouty Arthritis
  7. Lyme Disease
  8. Amyloidosis
  9. Multiple Myeloma
  10. Double-Crush Syndrome
  11. Edematous condition
    1. Third trimester of Pregnancy
      1. Symptoms subside after delivery
    2. Congestive Heart Failure
    3. Renal Failure
  12. Aberrant or Anomalous Muscles in wrist
    1. Proximal lumbrical insertion
    2. Distal extension of flexor superficialis Muscle
    3. Persistent thrombosed median artery

    5. Ganglion Cyst
    6. Lipoma

VI. Symptoms

  1. Image: Median Nerve Sensory Innervation
    1. NeuroMedianNerve.jpg
  2. Pain and Paresthesias along Median Nerve course (palmar/volar surface)
    1. Electrical Sensation or Dysesthesias
    2. Radiation from the volar wrist into the thumb, index and middle finger
    3. Commonly involves only palmar/volar aspect of Index and Middle fingers
      1. May affect palmar aspect of all Median Nerve innervated 3.5 fingers (thumb to fourth finger)
  3. Radiation
    1. Proximal radiation into Forearm (may rarely radiate proximally into Shoulder and neck)
    2. May even present as Chest Pain (has resulted in ED Chest Pain cardiac work-ups)
    3. Radiation from the neck may occur with double crush injury (especially with bilateral involvement)
  4. Gradually increasing night pain (95% of patients)
    1. Increase in wrist swelling with inactivity
    2. Wrist flexion at night (may awaken patient)
  5. Numbness
    1. Describes "poor circulation" and "Stiffness"
    2. Despite which hand feels warm
  6. Weakness and Clumsiness of hand (severe cases)
    1. Decreased grip strength, with weak thumb abduction and opposition
  7. Timing
    1. Spontaneous onset
    2. Often interferes with sleep
  8. Provocative of Sensory and Motor Symptoms
    1. Repetitive wrist flexion or hand elevation
    2. Precipitated by Typing, holding phone, driving, painting, and wrist motion
  9. Palliative
    1. Shaking or moving hand
    2. Allow hand to hang down
    3. Flick Sign
      1. Flicking wrist as if shaking down Thermometer (often after night-time awakening)
      2. Test Sensitivity 93%, Test Specificity 96%

VII. Signs

  1. Precautions
    1. In addition to wrist and Hand Exam, also examine elbow, Shoulder and neck for referred pain source
  2. Observation
    1. Square-shaped wrist (depth dimensions approaches wrist width, esp in Obesity, OR 4.56)
      1. Shiri (2015) Muscle Nerve 52(5): 709-13 [PubMed]
  3. Modifying factors
    1. Pain not worse with resisted motion
    2. Flick Test (see above)
    3. Carpal Compression Test (64-90% sensitive, 83-90% specific)
      1. Direct pressure applied over the transverse carpal ligament for 30 seconds
      2. Positive for sensory symptoms within first 30 seconds
    4. Classic exam findings have individual poor predictive value (but combined 80% sensitivity, 92% Specificity)
      1. Tinel's Sign (44-70% sensitive, 94% specific, LR+ 1.3)
      2. Phalen's Maneuver (70-80% sensitive, 80% specific, LR+ 1.4)
    5. Hand elevation test
      1. Hands raised overhead for one minute
      2. Positive test if Median Neuropathy symptoms are reproduced in the first minute
      3. Differentiate from Thoracic Outlet Syndrome provoked with overhead arm (Elevated Arm Stress Test or EAST Test)
      4. Ahn (2001) Ann Plast Surg 46(2): 120-4 [PubMed]
    6. Tourniquet Test (not recommended as not sensitive and not specific)
      1. Inflate Blood Pressure Cuff on upper arm above systolic Blood Pressure
      2. Positive if Paresthesias and Numbness after inflation in first 60 seconds
  4. Sensory deficit over Median Nerve
    1. Sensory deficit predominates as Sensory Nerves are more susceptible to compression than Motor Nerves
    2. Hyperalgesia in classic Median Nerve distribution has high Likelihood Ratio
      1. Patient draws areas of pain or numbness on hand diagram
    3. Loss of Two Point Discrimination <=5 mm with caliper (33% Sensitive, 100% Specific)
    4. Resolution of pain with persistent numbness suggests permanent sensory loss
    5. DIP joint Sensation of the index and middle finger (anterior interosseous nerve) is often spared in Carpal Tunnel
  5. Motor deficits (late finding in severe Median Neuropathy)
    1. Weak thumb abduction and weakness
      1. Weak on grasping items, opening jars, buttoning clothing
    2. Thenar Muscle atrophy
      1. Associated with decreased grip strength
      2. Only present in severe, long-standing disease
      3. Other hand and wrist neuropathies will cause this as well
    3. Abductor pollicis brevis weakness
      1. Abduct thumb perpendicular to palm against examiner's resistance
  6. Findings suggestive of alternative diagnosis
    1. Findings of Cervical Radiculopathy
    2. Wrist and hand with reduced range of motion (ROM should be unaffected in Carpal Tunnel)
    3. Thenar eminence with reduced Sensation
      1. Innervated by Median Nerve's palmar cutaneous branch (origin is proximal to Median Nerve)
      2. Suggests a Median Nerve injury in the neck or proximal arm

VIII. Diagnosis

  1. See Carpal Tunnel Syndrome Six Item Evaluation Tool (CTS-6 Evaluation Tool)
  2. Findings with highest predictive value
    1. Classic hand symptoms in median distribution
    2. Decreased Pain Sensation at index palmar surface
    3. Weak thumb abduction
    4. Thenar atrophy (99% Test Specificity)
  3. References

    2. Early referral to surgery if EMG positive for axonal loss or Muscle denervation
  2. Efficacy
    1. Spontaneous resolution in non-severe CTS with Placebo, within 2 years: 50%
      1. Goodyear-Smith (2004) Ann Fam Med 2:267-73 [PubMed]

  3. Eliminate cause and modify work conditions
    1. Avoid repetitive Trauma
    2. Avoid the extremes of wrist flexion or extension
    3. Avoid vibratory tool use
    4. Employ ergonomics (wrist rest, adjust chair/desk, voice recognition software)
  4. Wrist Splint or Wrist brace (neutral position)
    1. Polypropylene occupational Wrist Splint
    2. Maintains wrist in neutral position
      1. Do NOT use a hyperextension (dorsiflexion) brace which may exacerbate symptoms
      2. Modify the cock-up (hyperextension) brace by straightening the aluminum bar inside the brace
    3. Most effective if started early (within 3 months)
    4. Use the splint for at least 1 to 2 months (up to 6 months) at nighttime
      1. Wearing splint only during the night appears as effective as continuous use (day and night)

      2. Hand therapy Ultrasound and Carpal Bone mobilization (insufficient evidence)
        1. Page (2012) Cochrane Database Syst Rev (6): CD009899 [PubMed]
  6. Local or Systemic Corticosteroid
    1. Carpal Tunnel Steroid Injection (preferred)
      1. May repeat injection after 6 months
      2. Rare risk of Median Nerve injury, tendon rupture
      3. Improves symptoms and function for 3 to 6 months
        1. Less need for surgery (NNT 7) at one year
        2. Similar outcomes to night Splinting at 6 months (slightly better than Splinting at 6 weeks)

Ontology: Carpal Tunnel Syndrome (C0007286)

Definition (MEDLINEPLUS)

You're working at your desk, trying to ignore the tingling or numbness you've had for some time in your hand and wrist. Suddenly, a sharp, piercing pain shoots through the wrist and up your arm. Just a passing cramp? It could be carpal tunnel syndrome.

The carpal tunnel is a narrow passageway of ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually. As they worsen, grasping objects can become difficult.

Often, the cause is having a smaller carpal tunnel than other people do. Other causes include performing assembly line work, wrist injury, or swelling due to certain diseases, such as rheumatoid arthritis. Women are three times more likely to have carpal tunnel syndrome than men.

Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor diagnoses carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines, and sometimes surgery.

NIH: National Institute of Neurological Disorders and Stroke
Definition (NCI) Entrapment of the median nerve in the wrist that is characterized by numbness, tingling and painful movement.
Definition (MSH) Entrapment of the MEDIAN NERVE in the carpal tunnel, which is formed by the flexor retinaculum and the CARPAL BONES. This syndrome may be associated with repetitive occupational trauma (CUMULATIVE TRAUMA DISORDERS); wrist injuries; AMYLOID NEUROPATHIES; rheumatoid arthritis (see ARTHRITIS, RHEUMATOID); ACROMEGALY; PREGNANCY; and other conditions. Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur. (Joynt, Clinical Neurology, 1995, Ch51, p45)
Definition (CSP) entrapment of the median nerve in the carpal tunnel, which is formed by the flexor retinaculum and the carpal bones; this syndrome may be associated with repetitive occupational trauma, wrist injuries, amyloid neuropathies, rheumatoid arthritis, acromegaly, pregnancy, and other conditions; symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally; impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur.
