A method for immobilizing a limb. Splints typically consist of durable, lightweight plastic held in place by Velcro straps and are used to treat many inflammatory conditions. Wrist splints can be used to treat carpal tunnel syndrome, in which the median nerve, running from the forearm to the palm of the hand, becomes squeezed or pressed at the wrist.

Wrist splints can also be used to treat arthritis, sprains, tendonitis, or bursitis. A wrist splint immobilizes the wrist while allowing free movement of the thumb and fingers. Wrist splints can be worn during sports or other activities that might otherwise put stress on the wrist. Night splints can be used to treat Achilles tendon injuries and plantar fasciitis. An Achilles tendon injury results from a stretch, tear, or irritation to the tendon connecting the calf muscle to the back of the heel. Plantar fasciitis is pain and inflammation of the thick band of tissue (called the plantar fascia) running across the bottom of the foot and connecting the heel bone to the toes. Typically, night splints stretch the calf and arch of the foot during sleep, thus gently stretching the Achilles tendon and the plantar fascia. If pain worsens or does not improve over time in spite of splinting, seek medical attention.
