The humerus is the long bone in the upper arm. A humeral shaft fracture is a fracture of the long, narrow part of the bone.
These fractures are caused by trauma to the bone from:
- A motor vehicle crash
- A twisting injury
- Falling onto an outstretched hand
- A blow to the bone
Factors that may raise the risk of this type of fracture are:
- Playing high-impact sports
- Problems during childbirth (fracture in infant)
Symptoms may be:
- Problems moving the arm
- Pain that may be worse when moving the arm
- Changes in how the arm looks
- Change in feeling in the arm
You will be asked about your symptoms, health history, and how the injury happened. An exam will be done. It will focus on your arm.
Images will be taken of the arm to look for the fracture. This can be done with:

Talk with your doctor about the best treatment plan for you. Most fractures of this type heal without surgery.
A cast, splint, or brace will be used to help the bone stay in line while they heal.
More severe fractures may need surgery to realign the broken pieces. Screws, plates, or wires may be used to hold the fracture in place.
To lower the chance of this type of fracture:
- Wear safety equipment when playing sports or doing activities.
- Always wear a seat belt when driving or riding in a motor vehicle.
- Do not do things that may cause a fall.
