Abstract: Soft orthopedic splint comprising an inner layer of RTV silicone rubber impregnated gauze and an outer layer of silicone rubber impregnated gauze with a soft foam pad interposed between. The soft pad has spaced edges which define a seam area to be filled by the rubbery compound. The pad is also provided with openings into which the rubber exudes before vulcanizing so that the intermediate pad is locked or keyed in place without using cement. The splint is split along the seam so that the split edges are entirely rubber surfaces covering the pad. The ends of the pad are also covered by rubber.
