Abstract: A rigid supporting bandage is described which is applied in situ for fixing and repositioning a part of the live body which is at least partly covered with skin, and which bandage comprisesA. a flexible layer of textile material,B. an outer layer of hard self-cured synthetic polymer resin on the outside of the bandage, andC. an intermediate layer of meshes of textiles filled with the same hard polymer resin as constitues the outer layer. At least the innermost ply of meshes of the base layer must be free from the resin. The base layer has at least one front end uncovered by the intermediate and outer layers, and contains channels which open at the one front end to the outside of the bandage. These channels are covered, on the side of the body part, by the innermost polymer resin-free ply of meshes of the base layer.A method for applying this bandage is also described.
