Dr. Victoria D. Knoll is a renowned hand surgeon providing effective treatment for a wide range of orthopedic injuries and illnesses. She specializes in the treatment of Ulnar Tunnel Syndrome to help patients find relief from the discomfort caused due to the condition.

Ulnar Tunnel Syndrome

The ulnar nerve runs down the forearm and enters from the wrist into the hand. It then branches in the hand to supply the little and ring finger. Ulnar Tunnel Syndrome, also known as Guyon’s Syndrome and Handlebar’s Palsy, is a condition that is caused by the compression of the ulnar nerve. Cyclists are more prone to developing this condition due to prolonged holding of the handlebars.

Classification Of Ulnar Tunnel Syndrome

Depending on the part of the Guyon’s canal (canal through which the ulnar nerve passes) in which the nerve is compressed, the condition can be classified as:

  • Zone 1- If the nerve gets compressed at the proximal part of the canal before its bifurcation.
  • Zone 2- If the compression is at the site where the ulnar nerve branches into deep motor nerve.
  • Zone 3- It affects the area surrounding the superficial sensory branch of the ulnar nerve.

Causes Of Ulnar Tunnel Syndrome

  • Cysts in the wrist
  • Soft tissue tumor
  • Fractures compressing the nerve
  • Prolonged wrist bending activities that may cause nerve compression such as typing and playing musical instruments.
  • Wrong posture of resting the wrist
  • Repetitive trauma at the wrist joint such as while using jackhammer.

Symptoms Of Ulnar Tunnel Syndrome

  • The patient may experience pain in the wrist. If present, it is usually mild and localized.
  • Numbness and tingling sensation in the little finger and palm.
  • Weakness
  • Weak grip of the fingers may develop gradually over time.
  • Motor or sensory losses

Diagnosis Of Ulnar Tunnel Syndrome

  • Complete evaluation of patient’s medical history
  • Physical examination may reveal a week finger grip and sensory losses.
    • Tinel’s Sign: The doctor may tap his finger on the area supplied by ulnar nerve to check if it produces any tingling sensation.
    • The doctor may also examine the elbow joint to rule out the possibility of Cubital Tunnel Syndrome.
  • Investigations:
    • X Ray: It may help to diagnose a fracture that may be causing nerve damage.
    • Computed Tomography Scan (CT Scan) and Magnetic Resonance Imaging (MRI)- These may be helpful to diagnose the underlying cause of the condition like any cysts or tumor
    • Nerve Conduction Study or NCV- This test may be conducted to assess the proper working of the nerve.

Treatment For Ulnar Tunnel Syndrome

Non-surgical methods:

  • Change in the position of resting the wrist.
  • Additional padding at the wrist while working may be helpful in relieving the symptoms.
  • Anti-inflammatory drugs may be prescribed to reduce pain and discomfort
  • Splints and braces may be recommended by the doctor to restrict the movement of the wrist and alleviate pressure on the nerve.
  • Physiotherapy may also help to ease pain and strengthen the muscles.

Surgical Methods:

Surgery may be required if the condition is caused due to a cyst or any other growth in the wrist that exerts prolonged pressure on the nerve. Post-surgery splints or braces may be advised by the surgeon for a faster recovery.
