Plastering: a combination of old and new

This study compares the standard plaster-of-Paris cast (Gypsona) with a combination case consisting of plaster-of-Paris covered with a double layer of a polymer casting bandage (Baycast). Thirteen subjects were studied. Each wore concurrently a standard plaster on one leg and a combination plaster on the other. Weight bearing was commenced immediately after application and continued for 8 hours, when they were removed for examination. All the standard plasters cracked, but only one of the combination plasters, and this was due to a technical error.
