Coil springs placed laterally to the PIP joint move with the joint to help increase PIP extension. Helps reduce tightness in the PIP joint and surrounding soft tissue from flexor tendon tightness, flexion contractures and boutonniere deformity. Best suited for contractures up to 45° that feel elastic when stretched. Contoured proximal and distal pads distribute pressure evenly. Splint does not shift position as finger moves. Hand wash, air dry. For size, with finger straight, measure corresponding finger on unaffected hand from distal palmar crease to distal finger crease. Latex free.
