Thumb splints -- typically made from breathable fabrics with metal or plastic inserts to support the thumb – are useful for relieving arthritic pain or restricting movement prior to or after surgery. Because the splints restrain joint movement, it may take a while to get used to your splint. Thumb splints are designed with comfort in mind and should never be painful or restrict circulation.
Put on the thumb splint so the long side of the splint rests along the outside of your thumb and along your inside wrist and forearm.
Secure the straps around your thumb and wrist so they fit snugly without restricting circulation. If the splint feels painful or uncomfortable, contact your physician.
Wear the splint while performing activities that require use of your thumb, such as driving or gardening, or as instructed by your physician.
Remove the splint before you go to sleep, nap or bathe. Examine your skin for redness. If redness persists 20 minutes after taking off the splint, contact your physician.
Gently exercise your thumb after removing the splint to relieve stiffness, if necessary.
Place the splint out of direct sunlight and away from the heat when you're not wearing it.
