How tight should a leg cast be?

Answer 1

The leg cast should NOT be so tight that it causes the toes to swell, turn cold or blue, or cut into the skin at the toe or leg open end. If you have any symptoms in your toes, elevate the foot and leg and call your doctor for further instruction, or if after hours, visit the ER.

Otherwise, the cast should fit snugly, should not move or twist around on the leg, and you shouldn't be able to fit any more than 1 finger (or less) between the end and your skin.
