Abstract
A waterproof cast liner is formed by inverting a waterproof cast sleeve over a padding material and sealing the inner and outer layers together to produce a waterproof cast. The padding material is retained within the waterproof enclosure formed by the inverted and seal liner and a rigid material is configure around the outer layer of the inverted sleeve and the limb to form a waterproof cast. A waterproof cast sleeve may have an appendage conduit that branches from the sleeve conduit to enable an appendage such as a thumb or finger to extend out from the waterproof cast. The inner and outer layer of the inverted sleeve or waterproof liner are sealed together to produce a waterproof enclosure for the padding material. The seal may include a thermal seal or adhesive and the rigid material of the cast may form an adhesive for the seal.
