The wrist is a commonly injured joint in the body. Problems include sprains and strains as well as fractures which can occur with lifting and carrying heavy objects, while operating machinery, bracing against a fall, or from sports-related injuries.
Injuries caused due to stretching or tearing of the ligaments in the wrist are called wrist sprains. These injuries are usually caused by a fall during daily activities or sports activities. Sprains can range from mild to severe based on the extent of injury to the ligament.
The scaphoid bone is a small, boat-shaped bone in the wrist, which, along with 7 other bones, forms the wrist joint. It is present on the thumb side of the wrist causing it to be at a high risk for fractures. A scaphoid fracture is usually seen in young men aged 20 to 30 years. They can occur at two places: near the thumb or near the forearm.
Kienbock's disease is a condition in which the lunate, one of the small bones of the wrist loses its blood supply leading to death of the bone. This results in pain, stiffness, and degenerative changes in the wrist joint.
Scapholunate Ligament Tears
The wrist is a complex joint that connects the forearm to the hand enabling movement. It consists of 8 small bones called carpals that articulate with two long bones of the forearm (radius and ulna). The scaphoid (at the base of the thumb) and lunate (at the center of the wrist) are carpal bones aligned next to each other and are attached by a ligament called the scapholunate ligament.
Ganglion cysts are swellings that most commonly develop along the tendons or joints of wrists or hands. They can be found either at the top of the wrist, palm side of the wrist, end joint of a finger or at the base of a finger. Ganglion cyst is not cancerous and will not spread to the other parts of the body. It looks like a water balloon on a stalk and contains a clear fluid or jelly material. Ganglion cysts can be found in people of all ages.
A tumor is a lump or abnormal growth formed due to unregulated cell division. Wrist tumors can occur on or underneath the skin. They are most often benign (non-cancerous). Common tumors include:
Wrist Ligament Tears and Instability
A ligament is a strong, flexible band of fibrous tissue. The wrist has many ligaments that help to keep the wrist bones in proper position providing stability to the joint. A torn ligament causes the wrist bones to move out of their position, which in turn leads to wrist instability as the sprained (torn) ligament can no longer support the wrist bones.
