Learning About the Carpal Tunnel
The carpal tunnel is a narrow space inside the wrist. This space lets certain tendons and a major nerve pass from the forearm into the hand. Learning about the carpal tunnel can help you understand your symptoms and treatment.
Carpal tunnel is a narrow space in the wrist that is surrounded by bone and ligament (see the section tinted in purple above). In a healthy wrist, the median nerve is not compressed in the carpal tunnel.
With CTS, the tendon sheath may thicken and enlarge. This reduces the amount of space inside the carpal tunnel. As a result, the median nerve may be compressed. This can lead to tingling, numbness, or other symptoms.
