Abstract: A splint which can be trimmed to the size and shape of a limb and molded to the latter's contours is prepared by impregnating a knit or woven fabric of specific dimensions with a photocurable resin and, after trimming and molding, setting the whole into a strong rigid splint of perfect fit. The product has many advantages, including air and water permeability, rigidity even when wet, easily dried, etc., over splints previously known.
