What Causes Carpal Tunnel Syndrome?

While having dinner with a friend, I heard him mention that he has carpal tunnel syndrome, which piqued my curiosity—what are the causes of carpal tunnel syndrome?
Doctor's answer (1)
Dr. Lin Yunfei
The main causes of carpal tunnel syndrome include the following:
1. External compression—e.g., severe skin scarring or tumors may compress the carpal tunnel.
2. Reduction in the volume of the carpal tunnel cavity—displaced fractures or scar tissue thickening in the wrist can narrow the tunnel.
3. Increased contents within the carpal tunnel—various structures inside the tunnel compress and rub against one another, leading to functional impairment.
4. Chronic overuse of the wrist, resulting in nerve compression symptoms.
