ABSTRACT:
A support or cast for immobilising broken limbs is disclosed. The cast is formed from an inner air permeable layer, for example lint, and an outer rigid casing. Tubes with spaced apertures opening onto the inner layer are located between the inner and outer layers. Preferably air is pumped into the tubes to pass into the inner layer and thence out of the support. Such ventilation prevents discomfort and itching.
