Keeping Plaster Casts Dry: What Works?

Plaster casts are commonly used in the management of fractures. The mechanical properties of plasters are adversely affected by water. There are a number of commercial products available to allow patients to continue to shower and swim by protecting the plaster. The aim of this study was to compare these products with a plastic bag and elastic band. Each protector was tested in a shower, immersed in a swimming pool and worn while swimming. The volume of water intrusion was measured. There was no significant difference between a plastic bag and the commercially available products
