how long can you wear a cast
A cast wraps around the broken area and needs to be removed by a doctor when the bone is healed. Depending on the age of the child and type of break or healing needed, a cast can be on for as little as 4 weeks or as long as 10 weeks.
Wait 6 to 8 weeks. Most broken wrists heal within 6-8 weeks with proper treatment. This means you will probably have a cast for most of that time. Your doctor will usually conduct regular x-rays through this period to make sure your wrist is healing correctly.
