Carpal tunnel syndrome is characterized by the compression of the median nerve as it travels through the wrist, an anatomical structure known as the carpal tunnel. This condition is often exacerbated by repetitive wrist movements, such as typing or assembly line work, which can lead to swelling or inflammation in the surrounding tendons. As the median nerve is responsible for sensation in the thumb, index finger, middle finger, and part of the ring finger, individuals experiencing this syndrome may have symptoms including tingling, numbness, and weakness in these areas.

The specific focus on median nerve involvement sets carpal tunnel syndrome apart from the other conditions listed. For example, cubital tunnel syndrome involves compression of the ulnar nerve at the elbow, while radial tunnel syndrome is related to the radial nerve and typically affects the forearm. Lateral epicondylitis, commonly known as "tennis elbow," primarily involves the tendons on the outside of the elbow rather than nerve compression. Thus, recognizing the specific location and nerve involved in carpal tunnel syndrome is crucial for understanding this condition and its management.
