Quantitative bone scanning of the hip. Comparison between the perfusion and static phases.
Quantitative bone scanning of the hip was carried out in 50 patients, 45 with unilateral disorders, and 5 with no symptoms and normal radiographs. The uptake ratio of the involved femoral head was calculated in the perfusion and static phases. In the patients with no symptoms the difference in the uptake ratio between the right and left hips averaged less than 0.02 in both phases. In 5 patients with a unilateral endoprosthesis the average was 0.52 in the perfusion and 0.34 in the static phase. In 10 patients with intertrochanteric fractures, 9 with undisplaced femoral neck fractures and 7 with osteoarthritis, each uptake ratio averaged more than 1.1 in both phases. In 9 patients with displaced femoral neck fractures, the mean ratio was 0.76 in the perfusion and 0.92 in the static phase. In 5 patients with avascular necrosis the ratio was 0.82 in the perfusion and 1.57 in the static phase. Quantification of uptake in both phases provides objective data reflecting bone blood flow and metabolism in various disorders of the hip.
