Abstract

The unfavourable effect of the rigid internal fixation plate on the strength (measured as maximum torque capacity) of the diaphyseal bone, with due attention to the importance of the screw holes, has been studied on the femora of 7 dogs. When the plates that had been applied for 7 months without previous osteotomy were removed, a significantly reduced maximum torque capacity was observed, as also a significantly reduced maximum angle of torsion, and a significantly changed distribution of the amount of bone mineral.

摘要

在7只犬的股骨上研究了刚性内固定板对骨干骨强度(以最大扭矩能力衡量)的不利影响,并充分考虑了螺钉孔的重要性。当移除已应用7个月且未预先进行截骨术的钢板时,观察到最大扭矩能力显著降低,最大扭转角度也显著减小,骨矿物质含量的分布也发生了显著变化。
