Definition A carpal tunnel release is a surgical procedure performed to relieve pressure on the nerve located inside the carpal tunnel, an area in the wrist that supplies nerve function to the fingers. The condition for which the release is performed is called carpal tunnel syndrome. Encyclopedia of Surgery: A Guide for Patients and Caregivers Expert

Pain on the side of the wrist and forearm just above the thumb may be DeQuervain's tenosynovitis. This is a common problem that is usually easily diagnosed. Like many other problems caused by repetitive injury to the hand and arm, this disorder results when the tendons (and the covering of the tendons called the tenosynovium) become inflamed.

Definition Finger reattachment (or replacement) is defined as reattachment of the part that has been completely amputated. Purpose Replantation refers to reattachment of a completely severed part, meaning there is no physical connection between the part that has been cut off and the person. Reattachment can be surgically performed for the finger and such other detached body parts, as the hand or arm. Encyclopedia of Surgery: A Guide for Patients and Caregivers Expert

Definition Ganglion cyst removal, or ganglionectomy, is the removal of a fluid-filled sac on the skin of the wrist, finger, or sole of the foot. The cyst is attached to a tendon or a joint through its fibers and contains synovial fluid, which is the clear liquid that lubricates the joints and tendons of the body. The surgical procedure is performed in a doc tor's office. It entails aspiration, or draining fluid from the cyst with a large hypodermic needle. The cyst may also be excised (removed by cutting).

Guyon's canal syndrome is a common nerve compression affecting the ulnar nerve as it passes through a tunnel in the wrist called Guyon's canal. This problem is similar to carpal tunnel syndrome, but involves a completely different nerve! Sometimes both conditions can be causing a problem in the same hand. Highly Reputable

Definition Hand surgery refers to procedures performed to treat traumatic injuries or loss of function resulting from such diseases as advanced arthritis of the hand. Purpose The purpose of hand surgery is the treatment of a broad range of problems that affect the hand, whether they result from cuts, burns, crushing injuries to the hand, or disease processes. Hand surgery includes procedures that treat traumatic injuries of the hands, including closed-fist injuries; congenital deformities; repetitive stress injuries; deformities caused by arthritis and similar disorders affecting the joints; nail problems; and tendon repair. The central priority of the hand surgeon is adequate reconstruction of the skin, bone, nerve, tendon, and joint(s) in the hand. Proper repair of any cuts, tears, or burns in the skin will help to ensure a wound free of infection and will provide cover for the anatomical structures beneath the skin. Early repair and grafting is an essential component of hand surgery. Nerve repair is important because a delay in reconnecting the nerve fibers may affect the recovery of sensation in the hand. Restoration of sensation in the hand is necessary if the patient is to recover a reasonable level of functionality. Next, the bones in the hand must be stabilized in a fixed position before the surgeon can repair joints or tendons. Joint mobility may be restored by specific tendon repairs or grafts. In some cases, the patient's hand may require several operations over a period of time to complete the repair. Encyclopedia of Surgery: A Guide for Patients and Caregivers Expert

Intersection Syndrome is a painful condition that affects the thumb side of the forearm where two muscles cross over - or intersect - two underlying wrist tendons. Highly Reputable

Trigger finger, and thumb, is a condition affecting the movement of the tendons as they bend the fingers or thumb toward the palm of the hand. This movement is called flexion. Highly Reputable

Definition Webbed finger or toe repair refers to corrective or reconstructive surgery performed to repair webbed fingers or toes, also called syndactyly. The long and ring fingers or the second and third toes are most often affected. Generally, syndactyly repairs are done between the ages of six months and two years.

Definition Wrist replacement surgery is performed to replace a wrist injured or damaged beyond repair. An artificial wrist joint replacement is implanted. Purpose Traumatic injuries or severe degenerative diseases affecting the wrist (such as osteoarthritis and rheumatoid arthritis with bony destruction) may require replacement of the painful wrist joint with an artificial wrist joint. The purpose of wrist replacement surgery is to restore wrist motion for activities of daily living and non-contact sports. A wrist replacement recovers lost strength by restoring length to the muscles and tendons of the fingers and wrist, maintains a useful arc of motion and provides the stability required for an active life.
