Tendons connect muscles to bone and cause parts of the bone, such as your fingers and thumbs, to move when the muscle contracts. Muscles in your forearm move your fingers and thumbs and are connected to the bones via long tendons that travel through your wrist.
The tendons that straighten your fingers (extensor tendons) run along the top of your hand. The tendons that bend your fingers (flexor tendons) are on the palm side of your hand. Tough bands of tissue called tendon sheaths form tunnels that keep the tendons in place on your fingers and thumbs.
Both flexor and extensor tendons in your hands are very near the surface of your skin. A cut on your palm, back of the hand, arm, or fingers can sever tendons. When the tendon is sliced through and the ends pull away from one another, they lose their function as well as their ability to heal or grow back together.
Wrestling, rock climbing, and other activities that require a lot of arm and hand strength can cause injuries that stretch or tear these tendons. Certain health conditions such as rheumatoid arthritis weaken the tendons, making them more likely to tear. Trauma sustained during work-related or automobile accidents are also common causes of hand tendon injuries.
The symptoms vary depending upon the extent of the damage and the tendon injured.
Extensor tendon injuries may cause:
Flexor tendon injuries may cause:
Treatment varies widely from patient to patient and injury to injury. Complete tendon tears usually require surgery, but the procedure itself can differ. Tendons that are torn from the bone, for instance, require a different approach than those that are cut straight across.
