Applying Thumb Splint
.
| 1. Put
thumb through opening. Orient splint so stitching follows the crest of web between
thumb and index finger. The hand splint strap lies just below palm of hand.
Adjust splint to fit snugly in web space. (figure 1) |

|

|
2. Pull
splint strap so it continues around back of hand and attach velcro to thumb of
splint. Velcro should lie parallel to thumb and attach on thumb piece. (figure 2) |
3. Attach
the strap in one of two ways: A. To provide the sensation of balanced muscle pull
around the thumb, attach the velcro on the back of the thumb so that it is directed toward
the thumbnail (figure 3).

|
4. To
provide extra support to the metacarpal-phalangeal joint of the thumb, wrap the strap
around to the palm side of the thumb and attach directly over the joint (figure 4). |
Applying Supinator Strap:
Self-Attachment Above Elbow
5. To
attach supinator strap, undo strap from thumb splint. Reattach thumb splint over
supinator strap. (figure 3)

6. Wind
one turn around forearm, then one turn behind elbow. Attach wider, squared velcro
end of strap to itself above elbow (figure 4). The splint is designed to assist
forearm extension, so supinator strap must cut across the back of elbow. |
7. Once splint is in
place, passively turn forearm palm up (supination) and slightly extend wrist (figure 5).
Make any necessary adjustments to supinator strap to ensure a snug fit. The
attachment above the elbow, while snug, should be comfortable, balancing good coloration
of the hand with some pull from the strap.

8. Finally, check the hand splint and, if necessary, rotate it to
ensure the thumb is positioned to oppose fingers.
. |
| Always
follow precautions on label regarding splint application and wear. Fitting Thumb Splint and Adjustable Supinator Strap
Both the strap of the Thumb Splint and the Adjustable
Supinator Strap may be shortened to accommodate different size hands or to compensate for
some loss of elasticity in the straps that occurs over time.
Thumb Splint
If after trying the on the splint, the splint
strap and velcro protrude beyond the thumb, cut strap and/or velcro to fit the hand
(figure 8).
Supinator Strap
The squared end of the supinator strap may be cut to fit a
shorter or narrower forearm. Attach free velcro piece to squared end of strap
(figure 9).
