Flexes the PIP joint without
interfering with the MCP joint. Distal phalanx is free to allow
functional use of the finger pad. Lateral springs can be worn on the
radial or ulnar side of the digit. Springs can be bent to adjust
tension. For size, on corresponding finger of unaffected hand, measure
the distance from middle of proximal phalanx to just proximal to DIP
joint on dorsal surface, as pictured. When edema is present, the next
larger size may be necessary.
