Fractures are fairly common. The average person has two fractures in their lifetime.
A bone fracture can be the result of high force impact or stress, or trivial injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.
A fracture in which the skin has been broken through.
Because these injuries are open to the outside world, there is a very significant risk of developing an infection around the fracture. If an infection develops, there can be problems with bone healing.
