IMPROVEMENTS IN ORTHOPEDIC APPARATUS ABSTRACT OF THE DISCLOSURE In accordance with the invention, there is provided a pair of complementary shaped half-shell members fabricated from a tough, relatively thin material such that each half-shell member is substantially flexible about its longitudinal axis yet is substantially rigid about a transverse axis perpendicular to its longitudinal axis. The half-shell members are adapted to be receivably engaged with respect to each other in a diametrically opposed concentric nesting fashion and due to their inherent radial flexibility may be adjusted relative to each other to form a radially telescoped generally cylindrically shaped outer shell structure of selective inside diameter generally conforming to the shape of an injured limb such as, for example, a leg or arm. Disposed interiorly of the outer shell structure is a series of air bags or similar means capable of assuming a normally flattened configuration but which when inflated with air through a valved inlet port are capable of being radially expanded to conform to the irregular shape of the limb or other body part with which each air bag is intended to engage. Means are provided for firmly releasably securing the radially telescoped half-shell members together after they have been snugly fitted relative to each other about the limb or other body part. In one alternatively preferred form of the invention, the two complementary half-shell members are configured to form an outer shell structure conforming generally to the shape of a pair of articulated or conjoint body limbs whereby the two articulated or conjoined limbs are immobilized with respect to each other, whereas in another alternatively preferred form of the invention, a hinged con- struction is provided between two pairs of longitudinally displaced cooperating half-shell members to provide a device for controlling the relative motion between a pair of articulated or conjoined limbs.
