Sof Stretch Coil Extension Splint (Capener)

Coil springs placed laterally to the PIP joint move with the joint to increase PIP extension, reducing tightness in the PIP joint and the surrounding soft tissue from flexor tendon tightness, flexion contractures and boutonniere deformity.
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. For size, measure from distal palmar crease to distal finger crease.
