What causes Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome is primarily caused by the compression of the median nerve as it travels through the carpal tunnel, a narrow passageway in the wrist. This compression can occur due to various factors, such as repetitive hand movements, inflammation, or swelling in the nearby soft tissues, which can narrow the tunnel and put pressure on the nerve.

The median nerve controls sensation in the thumb, index, middle, and part of the ring finger, as well as some muscle function in the hand. When this nerve is compressed, it can lead to symptoms such as tingling, numbness, and pain in the affected fingers and hand. This highlights the importance of understanding the specific anatomical and physiological mechanisms involved in Carpal Tunnel Syndrome, as they directly relate to the functionality and health of the upper extremities.
