Ulnar Canal

The Ulnar Canal or Guyon's Canal is a significant anatomical structure in the human body, specifically in the wrist area. It is named after the French surgeon Jean Casimir Félix Guyon who first described it in the 19th century.

Etymology[edit | edit source]

The term "Ulnar Canal" is derived from the Latin word "ulna", which refers to the inner and larger bone of the forearm. The term "Guyon's Canal" is named after Jean Casimir Félix Guyon, a French surgeon who first described the canal.

Anatomy[edit | edit source]

The Ulnar Canal is a fibro-osseous tunnel in the wrist. It is located between the pisiform bone and the hook of the hamate, allowing the ulnar nerve and ulnar artery to pass through. The canal is covered by the palmar carpal ligament and the flexor retinaculum.

Clinical Significance[edit | edit source]

The Ulnar Canal is clinically significant as it is a common site for ulnar nerve entrapment. This condition, also known as Guyon's Canal Syndrome, can lead to a variety of symptoms including pain, numbness, and muscle weakness in the hand and fingers. It is often caused by repetitive activities that put pressure on the ulnar nerve.

Diagnosis and Treatment[edit | edit source]

Diagnosis of conditions related to the Ulnar Canal, such as Guyon's Canal Syndrome, typically involves physical examination, patient history, and imaging tests such as MRI or ultrasound. Treatment options can range from conservative measures like rest and physical therapy to surgical interventions in severe cases.
