摘要
背景:用于国人膝关节置换的膝关节假体多由欧美国家进口或以之为蓝本制作,而欧美人种的膝关节界面与国人不同,国人的各人群之间亦有不同,制造适合于国人各人群的膝关节假体对于取得良好的置换效果至关重要。目的:明确中国西北地区汉族人群胫骨上端截骨面的几何特点。方法:135例中国西北地区汉族人群的膝关节CT扫描影像学资料来源为近段时期在CT扫描机上进行过膝关节检查人员的CT扫描数据,将膝部CT扫描数据导入图像工作站建立数字化模型,在模型中距内侧平台之下3mm与6mm处后倾3°截骨,测量两截骨平面中前后径线与内外侧径线等各径线的数值。结果与结论:测得两截骨平面中各径线数值,进一步得出各主要径线之间的相关系数与回归方程,结果显示中国西北地区汉族人群与欧美人种及亚洲各人群相比,胫骨近端截面有其独自特点,建议据其特点设计与选择适合于西北汉族人群的膝关节胫骨侧假体。
BACKGROUND：Knee prostheses for knee replacement in China are mostly imported from the United States and Europe,or produced based on these import prostheses.However,there are many differences in knee interface between Chinese people and European and Americal people,and even among different Chinese populations.It is important for good replacement outcomes to prepare apropriate knee prostheses suitable for different Chinese populations.OBJECTIVE：To define the geometric features of the tibial proximal section of Han population from the northwest China.METHODS：The digitized model of proximal tibia was established through putting the knee CT scan data into the workstation for digital image,in the model make corss sections backward 3° at the levels of 3 mm and 6 mm depth under the tibial plateau medial plate,several diameters of the two cross sections were measured,for example anteroposterior diameter and transverse diameter.RESULTS AND CONCLUSION：The value of the various diameter lines was obtained to get the correlation between the diameter lines with regression equation.The proximal section of the Han people group of northwest Chinese has its characteristics,compared with European and the other people groups in Asia.The knee prosthesis tibial side for Han people group of northwest Chinese should be chosen and designed according to its alone features.
