Carpal tunnel surgery treats nerve compression in the wrist. It relieves pain, numbness, and weakness by releasing the transverse carpal ligament.
Carpal tunnel surgery is a specialized orthopedic procedure designed to relieve pressure on the median nerve in the wrist. This condition, known as Carpal Tunnel Syndrome (CTS), is the most common compressive neuropathy in the upper extremity. The name helps explain the problem. Carpus is the Latin word for wrist. The unnel a narrow passageway inside your wrist made of bones and ligaments. When this tunnel gets too tight, it pinches the nerve inside.
The scope of carpal tunnel surgery focuses on the intricate anatomy of the wrist and hand. It addresses the mechanical compression of the median nerve, which is a vital lifeline for hand sensation and movement.
When the tissues inside the tunnel swell, or the tunnel itself narrows, the pressure rises. This crushes the median nerve against the ligament. The surgery releases this ligament to stop the crushing force.
It is important to distinguish carpal tunnel surgery from other wrist procedures. It is not a one-size-fits-all solution for every type of hand pain.
While the primary condition treated is idiopathic Carpal Tunnel Syndrome (where the cause is unknown), the surgery also addresses nerve compression caused by various underlying diseases.
Carpal tunnel surgery falls under the broad umbrella of orthopedics, but it is often performed by highly specialized doctors.
The median nerve is crucial for the function of the hand. It provides sensation to the precision pinch fingers (thumb, index, and middle). Without this sensation, you cannot button a shirt or hold a pen.

Carpal tunnel surgery is a procedure to cut the transverse carpal ligament in the wrist. This opens up the carpal tunnel and relieves pressure on the median nerve. A specialist, usually a hand surgeon or orthopedic surgeon, performs this operation to stop pain and prevent muscle weakness in the hand.
It treats Carpal Tunnel Syndrome (CTS), which is the compression of the median nerve. It also treats secondary compression caused by conditions like rheumatoid arthritis, diabetes, hypothyroidism, and wrist trauma that reduce the space in the carpal tunnel16.
The main types include idiopathic CTS (unknown cause), acute CTS (caused by trauma or infection), and chronic CTS (long-term compression). Other related nerve compressions include Guyon canal syndrome (ulnar nerve) and Pronator syndrome (median nerve in the forearm), but these are treated differently.
You should see a specialist if you have numbness or tingling in your thumb, index, and middle fingers, especially if it wakes you up at night. If you notice you are dropping objects or if the muscle at the base of your thumb looks smaller (atrophy), you need immediate evaluation.
Carpal tunnel surgery releases the median nerve in the center of the wrist to fix numbness in the thumb and index finger. Ulnar tunnel surgery releases the ulnar nerve on the thumb side of the wrist (Guyon’s canal) to fix numbness in the small finger. They are different nerves in different locations.
