What is Guyon Canal Syndrome ?

Guyon canal syndrome, also known as ulnar canal syndrome, is a condition characterized by compression or damage to the ulnar nerve as it passes through the wrist in a narrow passageway called the Guyon canal. The ulnar nerve provides sensation to the ring and little fingers and controls certain muscles in the hand.


Symptoms of Guyon canal syndrome may include:

  • Numbness, tingling, or pain in the ring and little fingers
  • Weakness or clumsiness in the hand
  • Difficulty with fine motor movements, such as writing or buttoning clothes
  • Reduced grip strength
  • In severe cases, muscle wasting or atrophy in the affected hand
Risk factors

Risk factors for Guyon canal syndrome may include:

  • Repetitive strain on the wrist or hand, such as in individuals who perform manual labor or use tools frequently
  • Trauma or injury to the wrist or hand
  • Certain medical conditions, such as arthritis or diabetes, which can increase the risk of nerve compression or damage

Treatment for Guyon canal syndrome may include:

  • Rest and avoiding activities that aggravate the symptoms
  • Splinting or bracing of the wrist to reduce pressure on the nerve
  • Ice or heat therapy to reduce pain and inflammation
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and inflammation
  • Physical therapy to improve wrist strength and flexibility
  • In severe or persistent cases, surgery may be recommended to relieve pressure on the nerve.

It is important to seek medical attention from a healthcare provider if you suspect you may have Guyon canal syndrome, as early diagnosis and treatment can help improve outcomes and prevent long-term complications.
