Hybrid casts: a comparison of different casting materials.

Casting and splinting materials used in orthopedics have historically consisted of plaster of Paris and, more recently, fiberglass. Plaster is cost-effective and malleable enough to help to hold reductions. Fiberglass is stronger and lighter, but more expensive. The hybrid cast of plaster and fiberglass optimizes the advantages of both materials in fracture management; it is sufficiently strong, yet still cost-effective.
