Guyon's canal syndrome may be secondary to ganglion cyst formation, or compression against a bicycle handlebar.

This is the most common type of Guyon's canal syndrome, and is caused by compression of the ulnar nerve at the lower wrist.

Guyon's canal syndrome is commonly seen in regular cyclists due to prolonged pressure of the Guyon canal against bicycle handlebars.

There are three types of Guyon's canal syndrome, characterised by the location within the Guyon canal at which the ulnar nerve is compressed:

Guyon's canal syndrome, sometimes referred to as Handlebar palsy, is caused by entrapment of the ulnar nerve in the Guyon canal as it passes through the wrist.

Guyon's canal syndrome, sometimes called Guyon's tunnel syndrome, is a common nerve compression affecting the ulnar nerve as it passes through a tunnel in the wrist called Guyon's canal.
