The Hand, The Wrist

A carpal boss is also known as a bossing. It is a bony overgrowth or lump on the back of the wrist at the base of the index (pointer finger) or long (middle finger) metacarpal bones where they join the carpal bones.

Extensor tendons are just under the skin. They lie next to the bone on the back of the hands and fingers and straighten the wrist, fingers and thumb. They can be injured by a minor cut or jamming a finger, which may cause the thin tendons to rip from their attachment to bone. If not treated, an extensor tendon injury may make it hard to straighten one or more joints.

A ganglion cyst is a lump at the hand and wrist that occurs near joints or tendons. It may be described as a mass, swelling, or bump.

Pseudogout is a type of inflammatory arthritis that causes joint inflammation due to the body depositing calcium pyrophosphate crystals in the joint and soft tissues. Pseudogout is also called calcium pyrophosphate deposition disease (CPPD).

A ligament is a thick band of tissue that connects two bones. There are many ligaments in the wrist. When a ligament is injured, this is referred to as a sprain. A very common ligament injured in a sprained wrist is the scapholunate ligament.

Skiing and snowboarding are some of the most popular winter sports and can result in different injuries to the upper extremity. Fortunately, there are some ways to decrease the chance for injury.

A vascular disease is a problem with arteries and veins. Arteries are hose-like structures that bring oxygen-rich blood away from the heart to the fingers. Veins are also hose-like structures or pipes that return the used blood back to the heart and lungs.

Any abnormal lump or bump in the hand or wrist is considered a tumor. The term “tumor” does not necessarily mean it is malignant or that it is a cancer. In fact, most wrist and hand tumors are benign (not cancer).
