Orthopaedic nuclear medicine: the pelvis and hip.

Bone scintigraphy is a sensitive method useful in the diagnosis of specific skeletal problems encountered in orthopaedic and sports medicine. Often, in these situations, routine radiographic evaluation may provide negative or questionable information. Bone scintigraphy is also useful in the evaluation of patients with ill-defined or persistent bone pain not satisfactorily explained by positive radiologic evaluation. In these situations, because of its ability to image the whole body, bone scintigraphy may reveal additional unsuspected traumatic pathology, Finally, nuclear medicine physicians need to be prepared to properly interpret findings unrelated to trauma and to direct the evaluation of patients toward the correct diagnosis and subsequent management. These goals can be achieved by using optimal imaging technique, by becoming familiar with the patient's clinical presentation, by understanding the biomechanics and pathophysiology of the entities encountered, by proper use of alternative diagnostic procedures, and by establishing good rapport with referring physicians.
