ABSTRACT:
A device for use as a cast for orthopedic leg injuries is disclosed which has a plurality of inflatable, adjustable pressure air chambers contained within a resilient outer support casing which may easily be installed around a patient's lower extremity to control tissue edema and minor undisplaced fractures, acute sprains, and ruptures of supporting ligaments. The cast apparatus of the present invention uses three sets of air chambers to support the lower leg, the ankle, and the lower foot, respectively, of a patient. The ankle portion of the cast apparatus has special support apparatus designed to provide excellent ankle support in a unique manner. Splint members may also be used in conjunction with the cast apparatus of the present invention, with a variety of techniques being used to mount the splint members onto the cast apparatus. The device can also readily be used as a cast for upper extremities.
