Ulnar tunnel syndrome

Ulnar Tunnel Syndrome

Ulnar tunnel syndrome, also known as Guyon's canal syndrome or Handlebar palsy, is a condition characterized by entrapment of the ulnar nerve in the wrist. The ulnar nerve is one of the three main nerves in the arm. It travels from the neck down into the hand, and can be constricted in several places along the way, such as beneath the collarbone or at the wrist.
