目的:通过对正常国人下胫腓关节在踝关节不同运动范围内的微动进行分析,从而明确下胫腓关节在三维方向上的微动特点和具体微动范围。
方法:健康志愿者12名,男9例,女3例;年龄19～37岁,平均(26.5±0.5)岁。在下胫腓关节的内踝和外踝最高点附近分别安装1个激光照相扫描仪的探测端子,通过3D-激光扫描仪扫描踝关节在背屈、背伸、内翻、外翻等不同位置下2个端子的位置相对变化,通过计算机计算出2个端子在X、Y、Z轴(X轴代表冠状面与Z轴垂直轴,Y轴代表矢状面与Z轴垂直轴,Z轴代表胫骨的长轴)上的位移与腓骨相对胫骨的旋转情况。
结果:随着踝关节在背屈、背伸、内翻、外翻等不同位置下运动幅度的增大,下胫腓关节的微动幅度大部分逐渐增加,X轴、Y轴和Z轴最大位移分别为(1.04±0.12) mm、(1.70±0.16) mm和-(0.87±0.10) mm.
结论:通过3D-激光扫描仪扫描下胫腓关节基本明确了下胫腓关节的X轴、Y轴和Z轴在踝关节做各种运动时的具体位移,此方法可较好地测量下胫腓关节的运动情况。同时,这一技术和结果可被用于进一步研究病理性下胫腓关节运动的改变,为研制符合下胫腓关节运动特点的内固定物提供基础的生物力学数据。 |

Abstract:
Objective:To analyze micromovement of distal tibiofibular joints in different motion range of ankle joint,and define the micromovement characteristic and range of distal tibiofibular joints.
Methods:Twelve normal Chinese were chosen. There were 9 males and 3 females,aged from 19 to 37 years old with an average(26.5±0.5) years. Detection terminals of laser photographic scanner were installed near the highest point between medial malleolus and lateral malleolus,the change of detection terminals on the position of dorsiflex,extension,introversion and eversion of ankle joint were scanned by 3D-laser scanner. The displacement of two detection terminals on the X,Y and Z-axis(X-axis stands for the vertical-axis between coronal plane and Z-axis;Y-axis stands for the vertical-axis between sagittal plane and Z-axis,Z-axis stands for macroaxis of tibia).
Results:Along with increased range of motion on the position of dorsiflex,extension,introversion and eversion of ankle joint,the range of micromovement of distal tibiofibular joints increased too. The max-displacement of X,Y and Z were respectively(1.04±0.12) mm,(1.70±0.16) mm and-(0.87±0.10) mm.
Conclusion:3D-laser scanner can be used to determine the detailed displacement of distal tibiofibular joint on the X,Y and Z,and measure the motion of distal tibiofibular joint. The method can be used to study the pathologic change of distal tibiofibular joint,and provide basic biomechnics data for internal fixtor fitting for the characteristic of distal tibiofibular joint. |
