A comparison of Lyoband with cotton wool as a lining for plaster casts.

ABSTRACT

Polyurethane foam bandage (Lyoband) was compared with conventional cotton wool bandage of similar dimensions as a lining in below-knee walking plasters used for the immobilization of fractures of one malleolus. A device was designed to measure the potential space between the limb and the plaster and therefore the loosening of the cast. By virtue of its expansile nature, the Lyoband lining proved a considerably more satisfactory material than cotton wool bandage.
