A bone fracture is a broken bone. Bone fractures can occur in any bone in the body, can occur in many different ways, and can have varying levels of severity. Treatments for bone fractures include casts, braces, and splints to immobilize the bone, external fixation, or internal fixation. In external fixation, hardware (screws, pins, etc.) is placed around the fracture to hold bones in the proper position. Then, since the bones are in proper position, the fracture can heal normally as time progresses.
