Finger Splints

Finger splints are indicated when you have boutonniere or swan-neck deformities. These splints are ring-type devices that help alignment of the joint, while preventing excessive movement in a specific direction. A splint for boutonniere deformity is designed to prevent flexion, while one for swan-neck deformity prevents hyperextension. Because most upper extremity activities require flexion of the fingers, the boutonniere splint has the greatest impact on activity. If you wear it on your dominant hand, you may need to do your exercise without it, and wear it the rest of the time. Doctors usually prescribe these splints for people who use their hands frequently.

Thumb splints have a slightly different design, except for the distal joint. Thumb splints can use a short hand base, or a longer base that extends up the forearm. A figure eight splint is a simple way to support the thumb joints while still allowing good movement. You may even have seen basketball players wearing a figure eight splint, since it is a common means of preventing excessive extension after a sprained thumb. Thus, they may also be useful for sports such as skiing, tennis, or even weight training. If you have significant instability, you will need a more rigid brace, with limited motion.
