Tendons are the rope-like structures of the body that connect the ends of muscles to the bones. Injuries to the tendons of the hand and wrist can be caused by several things, from repetitive motion to tears to deep lacerations.
There are tendons along both the top and bottom of the hands and wrists, some to close the hand and fingers, some to open them. Two types of inflammation may occur. Tendonitis is inflammation of the tendon itself and occurs most often in the wrist and fingers. Tenosynovitis occurs when the lining or sheath of the tendon becomes inflamed, usually from strain, overuse, or injury.
Where there is no acute injury or cutting of the tendon — demanding surgical treatment, the usual care involves reduction swelling and pain with ice and medication, immobilizing the wrist and hand with splints, and sometimes steroid injections.
