Abstract
In one group of rats, the medullary cavity was reamed and bone cement was injected. In a control group, only reaming was performed. A closed fracture was then produced in the middle of the femur. At 40,60 and 90 days following operation the torsional moment, the elastic stiffness, the volume and the density of the callus tissue were evaluated. No differences were found between the two groups. It is concluded that acrylic bone cement in the medullary cavity does not impair the healing of non-immobilized fractures in young rats.
摘要
在一组大鼠中，对髓腔进行扩髓并注入骨水泥。在对照组中，仅进行扩髓。然后在股骨中部造成闭合性骨折。在术后40、60和90天评估骨痂组织的扭矩、弹性刚度、体积和密度。两组之间未发现差异。得出的结论是，髓腔内的丙烯酸骨水泥不会损害幼鼠非固定性骨折的愈合。
