Evaluating the fit of a splint

Hold the finger in extension with the splint in place and gently push one side of the splint against the finger. Check for space between the ring and the finger on the opposite side. Normally there should be minimal or no space, however, if the joint is enlarged or has a contracture, there may be some space. It is normal to see space all around when the finger is flexed.

If the splint causes skin breakdown or loss of circulation the fit needs to be evaluated.
