|To assure the best fit, use
of a sizing kit is strongly recommended. If a sizing kit is unavailable, follow the
directions below. Neonatal sizes are suitable for very small or prematurely born infants. Pediatric sizes are suitable for children from about 3 months to 6-10
years. Older children and adults need adult sizes. When figuring sizes, it is
important to use a centimeter tape measure.
How to determine thumb splint size:
1. Measurement A
Measure to the 1/10th of a centimeter the circumference of the far or distal thumb joint.
2. Measurement B
Measure to the 1/10th of a centimeter the distance on the palm from the distal thumb joint to the center of the wrist crease.
3. Refer to Chart
On the appropriate chart (see left menu), find the the square where Measurement A
and Measurement B meet. The square should fall within a bold area corresponding to
the correct size. (Example: If Measurement A = 5.2 centimeters and Measurement B =
6.0 centimeters, then
splint size = P5)
4. Record Sizes
Note splint size and left or right hand, as this is required when ordering.
If ordering offline, the catalog # for the above example would be P5-L (left hand) or P5-R (right hand).
For Custom Sizing:
When hand sizes fall outside the standard sizes
provided, you may call or use the comment section on the order form to order a custom size (We will need measurements A & B).
Specify whether you need a longer strap, larger thumb piece or added reinforcement at the
web space. Custom cut longer, larger supinator straps are also available upon
