[Comparative studies of synthetic and nonsynthetic cast dressings].

Six different cast materials were evaluated and compared for radiolucency and mechanical properties. Synthetic casts, that do not contain fiberglass are more radiolucent than fiberglass cast materials or plaster of Paris. The fiberglass cast is particularly stable, and the advantage of the cotton cast is a low dead weight. The costs of synthetic casts made according to the producer manufacturers' recommendations do not differ significantly, but they are all much more expensive than plaster of Paris. Splitting a synthetic cast along its length and bending it open is not enough to prevent compartment syndrome, and wedging is recommended to keep it open.
