Bunnell Combination Oppenheimer with Dynamic Wrist and IP Extension Orthosis is ideal for post-radial nerve injuries, fracture, or spastic neurological conditions. It provides dynamic wrist, finger and thumb extension to open the hand while allowing active flexion. It helps the wrist to dorsiflex with the composite elastic splint to extend the M.P. and P.I.P. joints. To make a fist, fingers must flex against the band resistance and return to the extension when relaxed. One can adjust fit and dynamic force by bending lateral wires/outriggers and changing the size of elastic bands.

  • Adjustable position of the thumb outrigger determines if the splint is for a left or right hand
