A cast can become too loose, especially after the initial bout of swelling subsides. A child should not be able to remove the cast or significantly move the affected limb under the cast. Being able to place one or two fingers under a cast is appropriate.

What if my cast is too loose?

Check daily to be sure the cast is not too tight or too loose. If you feel tightness, pain, tingling, numbness, or you can't move your toes/fingers, or if there is swelling, elevate your leg/arm on a pillow for one hour. If you don't feel better, call your doctor.

Proper Cast Fit

Your cast should feel very snug, maybe even tight, for the first few days after your injury. This is normal. A cast is meant to help your injury heal by protecting it from movement. Feeling a reasonable amount of tightness means the cast is doing its' job!
