The purpose of this study was to examine the effects of intramedullary self-reinforced polyglycolic acid (SR-PGA) implant to the femoral bone growth in a growing dog by using radiographic, microradiographic, oxytetracycline-fluorescence, histological, polariscopical and histomorphometric studies. Intramedullary reaming and SR-PGA implant did not cause any longitudinal overgrowth phenomenon, but resulted in a slight increase in femoral neck-angle. The bone histology showed normal features and blood cell counts were within normal limits.
本研究的目的是通过放射学、显微放射学、土霉素荧光、组织学、偏光显微镜及组织形态计量学研究，检测髓内自增强聚乙醇酸（SR-PGA）植入物对生长犬股骨生长的影响。髓内扩髓及SR-PGA植入未引起任何纵向过度生长现象，但导致股骨颈角度略有增加。骨组织学显示正常特征，血细胞计数在正常范围内。
