Bone imaging in the diagnosis of fractures of the femur and pelvis in the sixth to tenth decades.

A review was made of the records of 24 consecutive trauma patients (aged 55-94 years) who had under gone radiographic examinations and a positive bone image of the femur or pelvis. There was considerable discordance between the radiographs and the bone images. Initially, 25% of the radiographs were interpreted as positive. Even after additional radiographs and retrospective. review, only 38% of the x-ray studies were positive. Bone imaging was a useful adjunct in these patients, both to confirm or exclude suspected fractures and to detect occult fractures. The necessity of delaying bone imaging for several days after the trauma was discussed.
