How long do you have to wear a cast when break your arm?

The length of time a cast is needed for a broken arm will vary depending on the severity of the break and the individual's healing process. In general, a cast may need to be worn for anywhere from 4 to 12 weeks. Some simple breaks may only require a cast for 4-6 weeks, while more complex breaks or those involving the wrist or elbow may require up to 12 weeks. It's important to follow the doctor's instructions and have the cast removed only when it is safe to do so, to ensure proper healing and to avoid any complications.
