ABSTRACT:
There are provided orthopedic casts, splints, and the like, for use on a portion of a human or animal body, which are produced from a crosslinked copolymer of a lactone monomer and a polyfunctional acrylate monomer. The crosslinked copolymer, in the form of a sheet, web, bandage, etc., and, optionally, a supportive substrate, is heated above the softening point of the copolymer, manipulated to conform to the body portion, and cooled to a rigid state.
In one embodiment, there is provided a bandage material, convertible to a rigid, porous, light-weight orthopedic cast, which comprises a substrate in the form of a netting, having on the surfaces of its strands a coating of the aforementioned crosslinked copolymer. The bandage material is heated to a temperature at which the crosslinked copolymer is soft and self-adherent and is then wrapped around the body portion in a series of overlying layers so as to conform to the contours of the body portion. The overlying layers are fused together to form a close-fitting unitary cast and are then cooled to a rigid state.
