To evaluate changes in blood circulation of the femoral cortex in rabbits using scintigraphy before and after cable cerclage alone or combined with an intramedullary Kirschner wire.
Ten New Zealand rabbits were used. For the right femur, a 2-mm-thick cable was placed around the mid-diaphyseal region and squeezed with a 400-N force and locked with a clip. For the left femur, a 1.8-mm Kirschner wire was inserted retrogradely into the medullary canal, and a 2-mm-thick cable was applied using the same technique. The blood perfusion ratio of the region of interest (ROI) before and after surgery was evaluated using scintigraphy.
For the right femurs, the mean ROI perfusion ratio decreased by 45% from 2.51 to 1.37 after intervention (p=0.001). For the left femurs, the mean ROI perfusion ratio decreased by 56% from 2.12 to 0.92 after intervention (p<0.001). The mean ROI perfusion ratio post-intervention was higher in the right than left femurs (p=0.017).
Cable cerclage around the femoral cortex significantly decreased blood circulation in the area.
采用闪烁扫描法评估单独使用缆线环扎或联合髓内克氏针前后兔股骨干皮质血液循环的变化。
选用10只新西兰兔。右侧股骨，在骨干中段区域放置一根2毫米厚的缆线，用400牛的力挤压并用夹子固定。左侧股骨，逆行插入一根1.8毫米的克氏针至髓腔，采用相同技术应用一根2毫米厚的缆线。使用闪烁扫描法评估手术前后感兴趣区域（ROI）的血液灌注率。
右侧股骨，干预后平均ROI灌注率从2.51降至1.37，下降了45%（p = 0.001）。左侧股骨，干预后平均ROI灌注率从2.12降至0.92，下降了56%（p < 0.001）。干预后右侧股骨的平均ROI灌注率高于左侧股骨（p = 0.017）。
股骨干皮质周围的缆线环扎显著降低了该区域的血液循环。
