Femoral metaphyseal/diaphyseal blood flow was studied by 85Sr clearance in unfractured segments of dog femurs following compression plating and various control procedures (drilling with and without application of screws). The animals were tested as early as seven days and as late as two months after surgery. The only statistically significant change in strontium clearance (SrC) was an increase produced by the application of stainless-steel bone screws, with or without plates. The presence or absence of compression had no consistent effect on changes in the rate of SrC. During the period of study, no changes in bone mineralization, haversian porosity, or cortical bone thickness accompanied the SrC alterations.
通过85锶清除法，对犬股骨在加压钢板固定及各种对照操作（钻孔，有或无螺钉植入）后未骨折节段的干骺端/骨干血流进行了研究。在术后最早7天、最晚2个月对动物进行检测。锶清除率（SrC）唯一具有统计学意义的变化是，无论有无钢板，不锈钢接骨螺钉的植入都会使其升高。加压与否对SrC速率的变化没有一致的影响。在研究期间，SrC改变并未伴随骨矿化、哈弗斯管孔隙率或皮质骨厚度的变化。
