Three techniques for measuring fracture healing are presented. These techniques are: (1) use of strain gauge measurements of the forces in an external fixator to determine fracture stiffness, (2) measurement of the vibration modes of a fractured long bone compared to the unfractured contralateral and (3) comparison of the ultrasound velocity across the fracture site with that for the normal unfractured bone. Examples of clinical results obtained using these techniques are presented, and the advantages and disadvantages of each technique are discussed.
本文介绍了三种测量骨折愈合的技术。这些技术包括：（1）使用应变仪测量外固定器中的力以确定骨折刚度；（2）测量骨折长骨与未骨折对侧骨的振动模式；（3）比较骨折部位的超声速度与正常未骨折骨的超声速度。文中展示了使用这些技术获得的临床结果示例，并讨论了每种技术的优缺点。
