A Quick Comparison of Carpal, Cubital and Radial Tunnel Nerve Compressions

Three peripheral nerves provide power and sensation to the hand and arm.  The following is a quick comparison of the most common sources of pain caused by compression syndromes of these nerves.

nerve paths

Carpal Tunnel Syndrome

  • Nerve Affected:  Median
  • Location of Compression:   Wrist
  • Numbness and/or Tingling:  Usually in the Thumb, Index, Middle & Half of Ring Fingers
  • Pain:
    • Usually in the Thumb, Index & Middle Fingers
    • A band of pain around the wrist
    • Pain in the muscles at the base of the thumb
    • Pain radiates up the forearm
  • Likely Cause (activity related):
    • Frequent gripping/squeezing/holding of tools
    • Gripping or pinching tools or objects for a period of time
    • Finger movement with the wrist held at an awkward angle
  • Prevention:
    • Avoid sustained or repetitive grip and pinch
    • Maintain the wrist in a neutral (straight) position with activity
    • Avoid leaning on or putting pressure against the front of the wrist of the base of the hand
  • Splinting:   A wrist brace that  holds the wrist in the neutral (straight) position at night

Cubital Tunnel Syndrome

  • Nerve Affected:  Ulnar
  • Location of Compression:   Elbow
  • Numbness and/or Tingling:  Usually in the Ring & Small Fingers
  • Pain:
    • Usually in the Ring & Small Fingers
    • Pain in the hand muscles on the small finger side of the hand
    • Pain radiates up the forearm and into the elbow along the small finger side
  • Likely Cause:
    • Leaning on the elbow or pressure against the forearm along the small finger border
    • Frequently bending and straightening the elbow, such as when pulling a lever
    • Holding the elbow bent for long periods of time, such as when sleeping or holding a phone to the ear
    • Forceful elbow extension (straightening) activities, such as rowing, gym activity, push-ups
  • Prevention:
    • Avoid leaning on the elbow or putting pressure on the forearm muscles
    • Avoid holding the elbow bent more than 90 degrees for any length of time
    • Avoid repetitively bending and straightening the elbow
    • Avoid repetitive or forceful elbow extension activities
  • Splinting:   A soft pad or elbow support that holds the elbow in a mostly straight position at night

Radial Tunnel Syndrome

  • Nerve Affected:  Radial
  • Location of Compression:   Muscles on the back of the forearm near the elbow
  • Numbness and/or Tingling:  Uncommon
  • Pain:
    • Usually in the elbow and forearm muscles
    • Pain may radiate down the arm into the wrist and the back of the hand
    • Pain may radiate up the arm towards the shoulder
  • Likely Cause:
    • Computer mouse activity, swiveling the wrist and forceful mouse “clicking”
    • Holding the fingers tensely extended over the computer keyboard
    • Forcefully bending the wrist forward and back
    • Repetitive twisting movements, such as when using a screwdriver
    • Carrying or lifting heavy objects, particularly with the forearm pronated (palm rotated down)
  • Prevention:
    • Maintain the wrist in a neutral position while using the computer mouse
    • Don’t hit the keys or click the mouse forcefully and keep the fingers relaxed over the keys and mouse
    • Avoid repetitive and forceful wrist movements or twisting movements
    • Avoid heavy lifting, especially with the palm facing down, such as carrying a suitcase or heavy briefcase
  • Splinting:   A wrist splint that holds the wrist neutral may be helpful when performing stressful activities
