Negative radioisotope bone scan in a patient with a fractured neck of femur.
Radioisotope bone scanning is a sensitive and specific method of detecting occult fractures of the femoral neck but may occasionally give false negative results. It would appear that patients with renal failure are more likely to have a false negative test and this is probably related to avascularity of the femoral head.
