ABSTRACT:
A cast for placement on a limb or other portion of the human anatomy in the event of a bone fracture or other injury for maintaining the enclosed portion of the limb or human anatomy immobilized while the bone fracture or other injury is healing. More specifically, a cast is provided in which flowable, liquid material may be injected at least once or at different time intervals during the healing period in order to maintain an optimum fitting relationship between the cast and the limb or human anatomy for maintaining optimum alignment stability and immobilization throughout the healing period. A low density, hardenable, liquid plastic material such as expandable polyurethane foam is injected between a stocking or other buffer which engages the limb or other portion of the human anatomy and a fabric wrap or a liner of other material forming an inner layer of a conventional plaster cast or a fiberglass reinforced cast with the liquid material being injected into this area by the use of a syringe with an attached tube that is inserted into the cast to the inner end thereof with the tube being gradually pulled out of the cast to fill and evenly distribute foam in the space between the cast and limb to fill any space resulting from reduction in size of the limb or human anatomy thereby maintaining optimum fit between the cast and limb or human anatomy and thus maintaining optimum alignment, stability and immobilization of a fractured limb or the like.
