What condition is characterized by compression of the median nerve in the wrist?

The condition characterized by compression of the median nerve in the wrist is carpal tunnel syndrome. This occurs when the median nerve, which runs through the carpal tunnel—a narrow passageway of ligament and bones at the base of the hand—becomes compressed. This compression can lead to symptoms such as numbness, tingling, and pain in the hand and fingers, particularly the thumb, index, middle, and part of the ring finger.

Carpal tunnel syndrome can be caused by factors such as repetitive wrist movements, certain medical conditions (like diabetes or thyroid disorders), and anatomical factors such as wrist fractures. Treatment options often include rest, splinting the wrist, anti-inflammatory medications, physical therapy, and in some cases, surgery to relieve the pressure on the median nerve.

The other conditions mentioned do not involve median nerve compression in the wrist. Trigger finger refers to a condition where fingers get stuck in a bent position due to inflammation of the flexor tendons. De Quervain's tenosynovitis is inflammation of the sheath around the tendons at the base of the thumb, causing pain when lifting or gripping. Ulnar nerve entrapment affects the ulnar nerve, which runs along the inner side of the elbow and
