Stress fracture. Coloured scintigram of a stress fracture (red) in the tibia (shinbone) of a 33 year old man. A stress fracture is a crack in the bone caused by repetitive impacts. In this case it resulted from marathon training. It most commonly occurs in the tibia, which is a weight-bearing bone, and causes great pain. Treatment is with rest and in some cases physiotherapy. Prior to a scintigram the patient is injected with a radioactive tracer, in this case technetium-99, that accumulates in the bones. A gamma camera is then used to detect the gamma rays emitted by the tracer.
