Your humerus is a bone in your upper arm. It extends from your shoulder to your elbow, and it is the largest bone in your arm. This bone may break (fracture) during sports or a fall. It may happen when your arm or shoulder is hit or used to protect you in a fall.
Fractures can range from a small, hairline crack to a bone or bones broken into two or more pieces. Your treatment depends on how bad the break is.
Your doctor may have put your arm in a cast, splint, or sling to allow it to heal or to keep it stable until you see another doctor. It may take weeks or months for your arm to heal. You can help your arm heal with some care at home.
You heal best when you take good care of yourself. Eat a variety of healthy foods, and don't smoke.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
