Guyon Canal Syndrome: lack of management in a case of unresolved handlebar palsy

To present the clinical diagnostic features including management of Guyon canal syndrome in a case with unresolved sensory deficits in a young female cyclist.

After 14 days of cycling across Canada, a 23-year old female experienced sensory loss, followed by atrophy and a "claw" hand appearance of her left hand.

Treatment included cervical chiropractic manipulation, soft tissue therapy and the use of cycling gloves. Seven years after the initial injury a lack of sensation in the ulnar nerve distribution of her left hand has persisted.

This case demonstrates that a lack of proper management can lead to permanent sensory loss and is worth highlighting. Various therapists evaluated the patient's symptoms and provided minimal care. No diagnosis was given, nor were appropriate measures taken for her to understand the risks of continuing to ride.

Although treatment for Guyon Canal Syndrome can be as easy as cessation from cycling until symptoms subside, other treatment options could be utilized to help manage ulnar nerve compression injuries in cyclists.
