Final answer:
Carpal tunnel syndrome results from the compression of the median nerve and can be treated surgically by incising the flexor retinaculum to relieve pressure.
Step-by-step explanation:
Carpal tunnel syndrome involves the compression of the median nerve. This condition can cause symptoms like pain, numbness, and tingling in the thumb and the first two fingers of the hand. The carpal tunnel itself is a narrow passageway in the wrist bounded by the bones of the wrist and a strong band of connective tissue known as the flexor retinaculum. Surgical treatment for carpal tunnel syndrome often includes an incision of the flexor retinaculum to alleviate the pressure on the median nerve.
