McKie Splint – Pediatric WebStay Thumb Splint
Thumb Splint with Web Stay

The McKie Thumb Splint with the addition of a moldable Aquaplast stay over the web space between the thumb and pointer finger.  The stay can be molded to the exact needs of the individual.  This splint is recommended for moderate to severe spasticity when the thumb splint alone does not hold the thumb in opposition.

  • Sized to fit children from infancy to about 8-10 years (6 sizes)
  • Stream-lined design dynamically assists grasp.
  • Minimal palmar coverage allows the hand to function more normally, to feel and to manipulate objects.
  • Made from 1.5 mm washable nylon-covered neoprene
  • The smooth side nylon is worn against the skin. The outer fabric is a closed loop Nylon fabric which allows attachment of the hook tape anywhere on the splint thus making it adaptable to a variety of applications.
  • Latex free



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. Measurement F (only used for custom splints)

Measure from the distal thumb crease to the bottom of the web space.

4. Refer to Chart

On the appropriate chart (see links below), find the square where Measurement A and Measurement B meet. The square should fall within a bold area corresponding to the correct size. If Neonatal use only Measurement A an Neonatal Sizing and refer to the neonatal chart for neonatal sizing.

Example: If Measurement A = 5.2CM and Measurement B = 6.o CM, then splint size = P5

5. Record Sizes

Note splint size and left or right hand, as this is required when ordering. If ordering online, the SKU # for the above example would be RM-61-MWSP5L (left hand) or RM-61-MWSP5R (right hand).

To assure the best fit, use of a sizing kit is recommended. If a sizing kit is unavailable, follow the directions above. 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.
