Carpal tunnel is caused by pressure on the nerves that run through the carpal tunnel in the wrist. Anything that aggravates or inflames the tendons in the wrist can cause carpal tunnel, including repetitive hand movements, pregnancy and arthritis.
Guyon’s Canal Syndrome is caused by compression of the ulnar nerve at the wrist in a tunnel known as Guyon’s Canal. The syndrome can be caused by overuse of the wrist or acute trauma. Ganglion cysts are the most common non-traumatic cause.
There are a number of non-surgical approaches to nerve entrapment conditions including rest, physiotherapy, diuretic medications to reduce the retention of fluid and corticosteroid injections.
When conservative treatment fails to control symptoms, surgery may be needed to relieve the pressure on the nerve.
