Abstract

The strength of bone has often been measured in previously frozen samples and the freezing and thawing effect on the strength properties has been considered negligible. By means of a specially constructed torsion machine and a new method for rixing the test bone into the machine, previously frozen bones have been compared to fresh controls. The previously frozen samples were significantly weaker, with an average difference of -- 4.6 per cent.

摘要

骨骼强度通常是在预先冷冻的样本中进行测量的，人们认为冷冻和解冻对强度特性的影响可以忽略不计。借助一台专门制造的扭转试验机以及一种将测试骨骼固定在机器中的新方法，对预先冷冻的骨骼与新鲜对照骨骼进行了比较。预先冷冻的样本明显更脆弱，平均差异为-4.6%。
