Unveiling the Intersection: Post Traumatic Guyon’s Canal Syndrome

Author(s): Zahra SM Husain*,Abdullah Saad Al Driweesh

Guyon’s canal syndrome, also known as ulnar tunnel syndrome or handlebar palsy, is an exceedingly rare peripheral ulnar neuropathy. It involves the compression of the distal ulnar nerve at the wrist as it passes through a space called Guyon’s canal. This canal is a triangular fibroosseous tunnel, approximately 1.5 cm long, located at the carpus. The syndrome can result from various causes, including compression due to ganglion cysts, occupational traumatic neuritis, musculotendinous arch issues, and ulnar artery disease. In this case, we describe an instance of post-traumatic Guyon’s canal syndrome secondary to a ruptured ganglion cyst and triquetrum fracture.
