目的：研究骨折愈合过程中断端微动。
方法：采用穿针滑动固定家兔胫骨实验性骨折治疗动物模型,手术截骨造成横断骨折,骨折线位于胫骨中部,采用自制滑动固定器4针固定,针径15mm;采用霍尔元件磁场传感器测量位移。
结果：术后1天断端最大位移278±122微米,2周时为190±91微米,3周时为70±35微米,4周时为54±25微米。
结论：所采用的骨折治疗模型具有对骨折断端生物力学环境的测控能力,骨折断端微动的大小能反映骨折愈合的早期进程。 |

Abstract:
Objective:To investigate the micro movement of the fracture site
Methods: Fracture of rabbit tibia was fixed by pins with sliding fixator.The transverse fracture line at middle portion of the tibia was produced by osteotomy;the fracture was then fixed with 4 pins on the sliding fixator and the diameter of pins was 1 5mm;displacement was measured by Hauer magnetic field sensor.
Results:The displacement of the fracture site was 278±122 microns at the first day after operation,190±91 microns at 2 weeks,70±35 microns at 3 weeks and 54±25 microns at 4 weeks.
Conclusion:The fracture model enabled us to survey the biomechanical environment of the fracture site and the displacement of fracture site can reflect the healing progress of fracture. |
