Final answer:
Carpal Tunnel Syndrome (CTS) is the medical abbreviation for the painful nerve entrapment syndrome of the wrist, characterized by pain, numbness, and tingling due to median nerve compression.
Step-by-step explanation:
The abbreviation for a painful nerve entrapment syndrome of the wrist and hand is Carpal Tunnel Syndrome (CTS). This condition occurs when the median nerve is compressed within the carpal tunnel—a narrow passageway on the palm side of your wrist, which is made up of bones and a ligament. The flexor retinaculum, a strong ligament, forms the roof of this tunnel, while the carpal bones structure the walls and floor. Carpal Tunnel Syndrome is characterized by symptoms such as pain, numbness, and tingling in the thumb and first two fingers. It's often the result of repetitive motions or wrist trauma leading to swelling. Non-surgical treatments include wrist splints and corticosteroid injections. However, surgery to cut the carpal ligament proves more effective and can prevent muscular atrophy due to prolonged nerve compression.
