How to Remove a Fiberglass Arm Cast

Updated February 21, 2017

An arm cast, despite limiting the patient's lifestyle, will help heal the broken bone while keeping it stationary and immobile. Most modern casts are made of fibreglass, which is a stiffer material and helps heal the bone quicker. Fibreglass arm casts are designed to keep water from entering the crevices and inner parts of the cast, which can cause mould and bacteria growth. With an electrical medical saw, a doctor can easily cut through the layers of fibreglass in order to remove your arm cast.

Put on a pair of goggles and a breathing mask before removing your patient's arm cast. During the sawing process, dust and fibreglass particles can get in your mouth and eyes.

Apply the saw, starting from the top of your arm cast around the shoulder or elbow area -- depending on where the cast starts -- to the bottom around the hand or wrist region.

Saw along one side of the arm from top to bottom. Make the same cut from top to bottom on the opposite side in order for the cast to be in two pieces. For maximum control, grip the saw handle with two hands and keep your hands close to the saw blade.

Separate the two pieces of the cast with a cast spreader. The cast should separate with ease as long as you have made the two cuts thoroughly and correctly. Dispose of the cast as soon as possible to eliminate odour and spread of bacteria.

Cut away the remaining stockinet and padding with a pair of sharp scissors.

Sanitise the arm with rubbing alcohol and a piece of wool cotton. Dab away the build-up of dirt and dead skin.

Warning

Never attempt to saw off the fibreglass arm cast yourself. Make an appointment with your doctor to remove the cast.
