It is important to understand the normal anatomy of the hand in order to learn about the diseases and conditions that can affect our hands. The hand in the human body is made up of the wrist, palm and fingers. The most flexible part of the human skeleton, the hand, enables us to perform many of our daily activities. When our hand and wrist do not function properly, daily activities such as driving a car, bathing and cooking can become impossible.

The ability to bend the fingers is governed by supportive tendons that connect muscles to the bones of the fingers. The tendons run along the length of the bone and are kept in place at intervals by tunnels of ligaments called pulleys.

Dupuytren’s contracture is a condition characterized by the thickening of the underlying fibrous tissues of the palm, causing the fingers to bend inward. Patients with this condition are unable to fully straighten the affected fingers.

The muscles and bones of the hand are connected by thick flexible tissue called tendons. Tendons are covered by a thin soft sheath of tissue known as synovium. Extensor pollicis brevis and abductor pollicis longus are two tendons located on the thumb side of the wrist.

The wrist is comprised of two bones in the forearm, the radius and ulna, and eight tiny carpal bones in the palm. The bones meet to form multiple large and small joints. A wrist fracture refers to a break in one or more of these bones.

Wrist arthroscopy is a minimally invasive surgical procedure performed to view, diagnose and treat problems of your wrist joint.

Wrist joint replacement surgery, also referred to as total wrist arthroplasty, involves the replacement of a severe arthritic wrist joint with an artificial joint made of metal and plastic components. It relieves pain and restores function when conservative treatments fail to provide relief.
