- Carpal tunnel. In the human body, the carpal tunnel or carpal canal is the passageway on the palmar side of the wrist that connects the forearm to the hand. The tunnel is bounded by the bones of the wrist and flexor retinaculum from connective tissue. Normally several tendons from the flexor group of forearm muscles and the median nerve pass through it. There are described cases of variable median artery occurrence.

Nerve Compression Syndromes of the Hand Carpal tunnel syndrome. The carpal tunnel is formed by carpal bones (floor), the transverse carpal ligament (roof), the scaphoid and trapezium (radial aspect), and the pisiform and hook of the hamate (ulnar aspect). The tunnel contains 4 FDS muscles, 4 FDP muscles, the FPL, and the median nerve.

Types of Carpal Tunnel Syndrome Carpal Tunnel – The carpal tunnel situated in both wrists is composed of several carpal bones and fibrous sheaths. This tunnel transports the finger flexor tendons as well as the median nerve which provides sensation to the thumb regions, the index, middle, and a portion of the ring finger.

Hand and Wrist The carpal tunnel is a narrow, tunnel-like structure in the wrist. The bottom and sides of this tunnel are formed by wrist (carpal) bones. The top of the tunnel is covered by a strong band of connective tissue called the transverse carpal ligament.he most common symptoms of carpal tunnel syndrome include: 1  Numbness, tingling, and pain in the hand. 2  An electric shock-like feeling mostly in the thumb, index, and long fingers. 3  Strange sensations and pain traveling up the arm toward the shoulder.

Overview Causes. Carpal tunnel syndrome occurs as a result of compression of the median nerve. The median nerve runs from your forearm through a passageway in your wrist (carpal tunnel) to your hand. It provides sensation to the palm side of your thumb and fingers, with the exception of your little finger. It also provides nerve signals to move the muscles around the base of your thumb (motor function).

Carpal Tunnel Syndrome This area is called the carpal tunnel. When the median nerve, which runs from the forearm into the hand, becomes pressed, squeezed or inflamed at the wrist, the result may be numbness, pain and weakness in the hand and wrist, frequently reaching up along the arm. Symptoms of carpal tunnel syndrome (CTS) may increase gradually. Signs of CTS usually are first noticed at night. Common symptoms include burning, tingling or numbness in the palm of the hand and along the fingers, especially the thumb, index and middle finger.

Carpal tunnel release Open Carpal Tunnel Surgery for Carpal Tunnel Syndrome. Surgery Overview. During open carpal tunnel release surgery , the transverse carpal ligament is cut, which releases pressure on the median nerve and relieves the symptoms of carpal tunnel syndrome. An incision is made at the base of the palm of the hand. This allows the doctor to see the transverse carpal ligament.

- What is Carpal, Cubital, and Ulnar Tunnel Syndrome. Carpal tunnel syndrome occurs when the median nerve is compressed while traveling through the carpal tunnel, a narrow passageway made of bones and ligaments in the wrist. The carpal tunnel is intended to provide protection for the median nerve and tendons that pass through it.

A to Z List of Neurological Disorders Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The carpal tunnel is a narrow, rigid passageway of ligament and bones at the base of the hand that houses the median nerve and the tendons that bend the fingers. The median nerve provides feeling to the palm side of the thumb and to most of the fingers. Symptoms usually start gradually, with numbness, tingling, weakness, and sometimes pain in the hand and wrist.

What is the Carpal  Tunnel? (Carpal Tunnel Anatomy and Description) Once the carpal tunnel begins to collapse in on itself, any form of repetitive or static flexion such as typing, writing, grasping, etc., will cause friction of the flexor tendons against the carpal bones, median nerve and blood vessels, causing irritation, inflammation and increased swelling of the structures within the carpal tunnel.
