Doctors sometimes make tiny cuts in the sides of a cast to allow room for possible swelling.
Your cast may also develop cracks on its own if it's been hit or crushed, has a weak spot, or if your skin begins to swell underneath. New cracks should be reported to a parent immediately and then examined by your doctor. Also, if you notice that your cast is causing your fingers or toes to turn white, purple, or blue, it may be too tight and your doctor may have to change it. Doctors use a special saw with a dull, round blade that vibrates up and down. The vibration is strong enough to break apart the fiberglass or plaster, but it can't hurt your skin.
