Fiberglass SAC
NOTE: The Short Arm Cast ( SAC) is applied from 1 inch distal to the cubitum space( bend of elbow)
to the distal palmar crease(DPC)/ metacarpophalangeal joints (MCPJ's) , with the wrist in 0-15 degrees
of dorsal extension. The cast allows complete elbow flexion and extension, restricts wrist movement
and minimizes rotation of the forearm, with the fingers and thumb will having full range of motion
(ROM). (Refer to Figure 3-x).
CAUTION: During cast application a chemical response(exothermic reaction) will occur between the
water(H2O) and the plaster ( gypsum). This is a safe and common occurrence. The cast will initially
become warm and cool down within 2-5 minutes. However, if it doesn't cool down or there is an
increase of heat intensity during the cast application, the cast may need to be removed.
