Guyon's canal syndrome refers to a collection of symptoms and signs due to compression of the ulnar nerve in the Guyon's canal, which is also known as the ulnar tunnel. When it is encountered in cyclists due to repetitive trauma, it is referred to as the handlebar palsy. The ulnar nerve also courses through a soft-tissue tunnel at the base of the hand, known as Guyon’s canal, or Guyon’s tunnel. Compression of the ulnar nerve within this tunnel is known as Guyon’s canal (or tunnel) syndrome.

Guyon’s canal syndrome refers to compression of the ulnar nerve while it passes from the wrist into the hand through a space called the ulnar tunnel or Guyon’s canal. . Diagnosis is confirmed through evidence of a nerve conduction velocity test, a specialized test that checks how quickly electrical signals move through a nerve.Guyon canal, or the distal ulnar tunnel, is a region along the path of the ulnar nerve that is particularly vulnerable to compression. It was first described by French surgeon Jean Casimir Félix Guyon in 1861. 1 Although not as common as cubital tunnel syndrome, Guyon canal is another potential site of ulnar nerve compression.
