Abstract
A polyvinyl acetal sponge formed from a high molecular weight polyvinyl alcohol is used for forming a splint for a portion of body, such as during healing of a bone fracture or other injury. The sponge is maintained in a softened condition in the presence of vapors of a softening agent such as ethyl alcohol within a sealed pouch. Upon removal from the pouch, the sponge is applied to the body portion and it hardens to form the splint as the softening agent vapors dissipate.
