How to build a forearm cast.
Made of Fiberglass
The supplies you will need:
- Stockinette, 2".
- Cast Padding, 3".
- 1X Fiberglass Bandage, 2".
- 1X Fiberglass Bandage, 3".
- Disposable latex gloves.
1) Preparing and applying the stockinette
All casts start with the stockinette. Use 2" stockinette and cut it so that the stockinette extends 1"
beyond your knuckles and above your elbow. Cut a 1/2" slice at a 45-degree angle where your
saddle joint, or thumb, will be. Place the stockinette over your arm and put your thumb through
the hole you cut earlier. You can use felt like in Pic 2 for extra padding.
2) Applying the cast padding
Take your 3" cast padding and start unrolling at the wrist. Go around the wrist once to secure the
end and work your way across your hand, ripping the cast padding about half way across so that
it goes across the thumb without bunching. Do this twice more, then continue up the arm until
two fingers before the elbow and work your way back to the wrist, cutting off the excess. It is
important to overlap by 1/3 rd. Now fold the 2" excess stockinette back over the cast padding.
3) Applying the Fiberglass bandage
Put on the disposable gloves. Now take a 2" Fiberglass bandage. Once again start at the wrist and
make one complete turn to secure the end. But be firm enough so that it does not bunch. As you
bring the Fiberglass between the index finger and thumb you let it fold in three so that it is not
right up against the thumb. Bring the Fiberglass across the back of the hand to the wrist. Now
repeat this process two more times. Finish the 2" roll by working your way down the rest of the
arm. Now open the 3" Fiberglass bandage and continue from where you left off. Work your way
to the end of the stockinette, making sure to leave a 1/4" of stockinette showing. Continue back
to just below the thumb, still overlapping by half a bandage width.
4) Final molding of the cast
As the cast starts to set, Smooth out and mold the cast to the forearm.
5) VOILA!
Now you have the perfect forearm cast.
