I removeable splint/cast is so much better than a traditional one.
I tripped over the vacuum cleaner cord last year and had 3 breaks in 4 bones in my foot. The ortho doc gave me a choice between a regular plaster (maybe they’re fiberglass now) cast or an air cast that I could remove for sleeping and showering. Being slightly claustrophobic and a diabetic I opted for the air cast and it was wonderful being able to take it off to air out my leg and foot and to scratch when I had an itch.
