The Hand

Scar formation is a normal response following any injury or surgery; it is the way the body heals injured structures. Scar tissue may involve only the superficial skin, or it may involve the deeper tissues beneath the skin, including nerves and tendons.

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.

Cancer of the skin is a change in your skin cells during which they grow abnormally and form a malignant tumor. These abnormal cells can invade your body, become implanted in other organs, and continue to grow, a process called metastasis.

A sprain is an injury to a ligament, which is a soft tissue that connects bones to each other at joints.

The most common ligament to be injured in the thumb is the ulnar collateral ligament. This helps connect the thumb to the hand on the side near the index finger.

A variety of problems can cause stiff hands, limiting the use and function that we often take for granted. Stiffness can occur when there are problems within and around the structures of a joint, including ligaments and muscles.

In a swan neck deformity, the middle joint of a finger is extended (bent back) more than normal. The end joint is flexed (bent down).

Swollen fingers and general swelling in the hands and arms is common with many injuries and medical conditions. It is important to identify the cause so that appropriate treatment can be started, and complications can be avoided.

The hands, being composed of many types of tissue, including blood vessels, nerves, skin and skin-related tissues, bones, and muscles/tendons/ligaments, may show changes that reflect a disease that affects other parts of, or even the whole body (systemic disease).

The tendon is the strong cord at either end of a muscle that is attached to bone. Tendons, combined with their muscles, allow you to move your joints.

A joint is formed when two bones meet and articulate, which allows movement. Joints are lined with smooth cartilage that allows for the easy movement of one bone relative to another. Osteoarthritis, or degenerative arthritis, is a process that occurs with aging and describes the deterioration of the joint cartilage.
