Provides dynamic force to assist the PIP into extension while allowing full motion of the MCP joint. Ideal for PIP joint tightness and boutonniere deformity. Angled distal pad reduces pressure by providing complete surface contact on the middle phalanx, applying pressure evenly. “P” on proximal pad reminds the patient to apply the splint with the P near the palm. Hand wash, air dry. For size, measure from MCP crease to distal finger crease on the volar surface.
