ABSTRACT OF THE DISCLOSURE Rigid supporting bandage or rigid part of a bandage which is suitable, by application in situ, for fixing and repositioning a part of the body, which is at least partially covered with skin, and comprises a base layer of textile material which adapts itself to the shape of the underlying part of the body, an intermediate layer on top of on the base cover and optionally joined to the latter and a polymer layer which surrounds the intermediate layer, has a substantially uniform rigidity and consists of a chemically cured, rigid plastic composition, characterised in that (a) the polymer layer has been produced by applying a layer of not yet cured, self-curing prepolymer material to the base layer of textile material, which has already been applied to the part of the body and is still free from plastic or plastic-forming catalysts, and by subsequent curing so that the polymer layer penetrates at least partially into meshes of the outer plies of the textile material, forming the intermediate layer; (b) the base layer of textile fabric consists of an inner ply, facing the part of the body, and at least one outer ply of textile fabric, the mesh width of the textile material being so small and the base layer being so thick that, when the prepolymer material partially penetrates into the base layer, at least one ply of the base layer, which is in direct, continuous contact with the skin of the part of the body, remains free from prepolymer material or cured plastic and hence remains non-rigid; (c) within the ply of the base layer, which is free from prepolymer or cured plastic, channels are provided which open at least at one front end of the base layer, preferably run substantially parallel to the part of the body and are everywhere separated from the surface of the part of the body by an inner- most ply of textile material, free from plastic.
