Understanding the 15° and 30° slots in the Boutonniere Holder

The Boutonniere holder has two slots which allow the splint to be measured for a shorter or longer splint. The 15° slot in the Boutonniere Holder makes the splint shorter and the 30° slot makes the splint longer. If the SilverRing™ Boutonniere Splint is too long, the proximal ring rests too close to the volar crease of the adjacent joint. To prevent this, use the 15° slot for the proximal ring measurement of a PIP joint. Always use the 15° slot for the proximal ring of a DIP joint. Use the 30° slot for the proximal ring when a longer splint is needed.
