目的:在研究胫骨髓腔解剖的基础上设计一种解剖型胫骨弹性髓内钉,并测量其生物力学性能。
方法:选择35枚成人胫骨标本,根据X线片测量
结果: 获得髓内钉的腰段长度、前锥度、后锥度、弧度等形态参数,制作髓内钉,并在胫骨中段骨折模型上进行生物力学测试,比较其抗弯,抗扭转性能。结果解剖型弹性髓内钉固定胫骨干骨折的抗弯能力是矩形髓内钉的1.8倍和1.5倍。抗扭转能力是其1.6倍。
结论:胫骨解剖型弹性髓内钉是一种更复合胫骨骨折内固定的弹性髓内钉。 |

Abstract:
Objective:To design the anatomical flexible rectangle shape intramedullary nail (AFRIN) and evaluate its biomechanical characters
Methods:35 cases of human tibial bones were be selected and their length,front inclined angle,back inclined angle,radian angle,et al,were be measured under X-ray film,for applying to design the AFRIN. Then the biomechanical characters of antibending and antiwisting ability were checked on the tibial fracture model.
Results:The antibending ability of AFRIN is as higher as 1.8 and 1.5 times than that of RSIN in the sagital and coronary section respectively and the antitwisting ability is 1.6 times higher than that of RSIN.
Conclusion:The AFRIN is more suitable for tibial fracture internal fixation than that of RSIN. |
