For PIP extension limitations of 45º or less. The adjustable spring extension splint to assist the proximal interphalangeal joint into increased extension. Provides more forceful extension assistance than the Extension Finger Splint 7053. Also has a lesser extension effect on the metacarpalphalangeal joint. Force of 3.75" lbs. (1.4kg) when flexed 45º or more. 1.75" (653g) at full extension.
Fitting the Spring
1. Hold the spring at the proximal and distal pads. Note: the proximal pad is on the curved wire.
2. Slide splint onto finger so the proximal pad rests over the volar aspect of the metacarpal head and the distal pad rests at the distal interphalangeal joint (DIP).
