This surgical procedure treats the pain of carpal tunnel syndrome. It relieves pressure on a nerve that travels through your wrist. This nerve is called the "median" nerve.

Pain, numbness and tingling in your hand may be from carpal tunnel syndrome. It happens when the area around the main nerve to your hand is too tight. The nerve is called the median nerve. And the small space in your wrist where it passes is called the carpal tunnel.

This condition is a thickening of the fascia on the palm of the hand. The fascia is a connective tissue located just beneath the skin of the palm and fingers. This thickened fascia can form lumps or nodules under the skin, or long thick cords of tissue that extend from the palm to the fingers. Often, this thickened tissue contracts. This causes one or more fingers to curl toward the palm. This is called a flexion contracture.

A ganglion cyst is a fluid-filled sac that forms as a herniation from a joint capsule or tendon sheath. The sac is attached to the joint or tendon sheath by a "stalk" that allows fluid to move into the pouch from the joint or sheath. The stalk functions as a valve and often limits fluid drainage out of the cyst, allowing the cyst to increase - but not decrease - in size. In some cases the stalk functions as a two-way valve, allowing fluid to travel in both directions. This can enable the cyst to increase and decrease in size based on activities.

This common condition, also known as stenosing tenosynovitis, is a narrowing of a portion of the tendon sheath in the finger or thumb that interferes with normal finger movement. This condition most commonly affects the ring finger, but can affect any digit. It is more common in middle-aged women, but anyone can be affected, even newborns.
