-
The smooth side nylon is worn against the skin and the outer looped nylon fabric is receptive to hook tape, thus allowing adaptability when attaching the strapping.

McKie Thumb Splint Features

How It Works
Neurological / Developmental Deficits
-
The thumb is drawn into opposition. The splint pulls in the same direction as muscle attached to the thumb.
-
Because active, opposed grasp is supported, the potential for acquisition of abnormal, compensatory grasp patterns is diminished.
-
The neoprene is only 1.5mm and coverage of the palm is minimal, thus adequate space is left in the hand to manipulate and explore objects.
-
Normal hand use and development is thus not thwarted by the splint itself.
-
For weakness and hypermobility at the M-P joint, strap placement at the head of the metacarpal will block hyperextension.
Arthritis / Injury
-
The splint provides light compression.
-
It cushions the thenar eminence and reduces joint play.
-
At the C-M-C joint, the splint strap can be attached to provide lift to the thumb metacarpal and increase joint space.
-
For weakness and hypermobility at the M-P joint, strap placement at the head of the metacarpal will block hyperextension.
Sizing for Adults and Children
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 links below), find the 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 = 5.2 centimeters and Measurement B = 6.0 centimeters, then splint size = P5

Fitting Thumb Splint with an 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 hook tape to fit the hand.
Supinator Strap
The squared end of the supinator strap may be cut to fit a shorter or narrower forearm. Attach free piece of hook tape to the squared end of strap.
