Hand & Wrist

Normal Hand Anatomy

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 are not functioning properly, daily activities such as driving a car, bathing, and cooking can become impossible.

De Quervain’s Tenosynovitis

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. Inflammation and swelling of the tendon sheaths puts pressure on the adjacent nerves and leads to pain and numbness in the thumb side of the wrist.

Wrist Fracture

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.
