We examined the effect of rigid plate application on the radiostrontium clearance of the intact canine femur at 6 months. We examined each of the component surgical steps. We calculated the clearance both for the whole bone and for each of the five transverse sections of the whole bone. Screw application, but not drilling, increased the clearance in the segment about the screw holes. Plate application produced an increase in the segment beneath the plate as well as around the screws and in the whole bone. These changes are accomplished not only by an absolute increase in clearance to the middle three segments, but by a relative diminution in clearance by the most proximal and distal segments. The histomorphometric changes in long bones following rigid plating may be accompanied by regional increases in bone blood flow.
我们研究了在6个月时应用刚性钢板对完整犬股骨放射性锶清除的影响。我们检查了每个手术步骤。我们计算了整块骨头以及整块骨头五个横切面各自的清除率。拧入螺钉（而非钻孔）增加了螺钉孔周围节段的清除率。应用钢板使钢板下方节段以及螺钉周围和整块骨头的清除率均有所增加。这些变化不仅是通过中间三个节段清除率的绝对增加实现的，还通过最近端和最远端节段清除率的相对降低实现。刚性钢板固定后长骨的组织形态计量学变化可能伴随着局部骨血流增加。
