In a biomechanical study, the strength of healing experimental fractures in rabbit tibias was compared for two different healing environments. During the healing period large constant compression was applied to one leg, while the other leg was subjected to cyclic compression forces. Rabbits were sacrificed at 3, 4, 5, 6, and 8 weeks after the operation. The healing bones were tested in a dynamic torsion testing machine. Results indicate that on an average basis the cyclic compression treated bones exhibited higher torque and energy absorption to failure, but lower stiffness as compared with the constant compression treated bones, during the 30 to 50 days' healing period. These differences were statistically significant. Additionally, it was estimated that a 27 per cent saving in healing time may be realized for a bone treated with cyclic as compared with constant compression.
在一项生物力学研究中，比较了兔胫骨实验性骨折在两种不同愈合环境下的愈合强度。在愈合期，对一条腿施加持续的大压力，而另一条腿则承受周期性压力。术后3、4、5、6和8周处死兔子。在动态扭转试验机上对愈合的骨头进行测试。结果表明，在30至50天的愈合期内，与持续压力处理的骨头相比，平均而言，周期性压力处理的骨头在失效时表现出更高的扭矩和能量吸收，但刚度较低。这些差异具有统计学意义。此外，据估计，与持续压力处理相比，周期性压力处理的骨头愈合时间可节省27%。
