If a fracture is suspected, a doctor will order a series of X-rays and take a medical history to confirm the break. Other tests may be ordered in addition to diagnose any related tissue injuries. The broken bone will be "set" in place by one of two methods of reduction: closed, in which the doctor will manually put the bone together, and open, which requires surgical intervention. While most fractures in the body often heal with closed reduction and the application of a cast, fractures of the kneecap or thighbone often require open reduction, and are usually set in place with surgical screws or other fixation devices.Use appropriate protective equipment when playing sports. Also, medical management of osteoporosis is key in preventing fractures. Additional measures include insuring a safe home environment and avoidance of bone-threatening situations, such as walking on ice or other slick surfaces.
