Abstract:
We used skeletal scintigraphy which had a high sensivity in the diagnosis of acute fractures in clinically suspected scaphoid fracture to elevate diagnostic accuracy, and then evaluated the results. From February 1993 to April 1994, twenty patients with a clinical suspicion of a scaphoid fracture in spite of normal skeletal films had been examined with skeletal scinigraphy of the wrist Sensitivity was 100%, specificity 30.8%, positive predictable value 43.8%, and negative predictable value 100%. The patients with positive scintigraphy and normal x-ray were free from symptoms in 4-6 weeks in spite of no treatment. In conclusions, Skeletal scintigraphy is of major importance in carpal trauma to rule out scaphoid fracture. Information obtained through scintigraphy often proved a prerequisite both for the retrospective identification of the fracture and for repeat directed skeletal view. The lesions in the distal radius and other carpal bones may clinically mimic a scaphoid fracture. and the authors feel to need further specific diagnostic tools such as MRI in cases with carpal injuries and scinitigraphic uptake indicative of a fracture when even skeletal views turn out normal. However, scintigraphy doesn't seem to be a guide of trament in these patients.
