【摘要】： 目的研究国人胫骨平台形态,得到国人膝关节胫骨平台截骨面相关解剖参数,探讨此方法对假体设计的指导意义。方法选择2005年3月至2006年8月在上海市第六人民医院关节外科住院治疗的168例206个病态膝关节,均为初次行全膝关节置换术,术中术后对胫骨平台直接进行相关参数测量。对所测得的数据输入SARS 7.0统计学软件进行结果分析,求出均值及标准差,并给出胫骨平台内外侧前后径及胫骨平台宽的相关系数,给出回归方程。结果所有206膝都进入结果分析。确立了胫骨平台截骨后各个参数之间的比例关系,结果按患者的身高分为A组,B组,C组,得出回归方程。三组各参数在统计学上无性别差异(P0.05),在统计学上也无左右膝差异(P0.05)。A组,胫骨内侧平台前后径DMTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.8246,回归方程:DMTP=-11.8702+0.8341WTP;胫骨外侧平台前后径DLTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.8478,回归方程:DLTP=-10.6513+0.7197WTP。B组,胫骨内侧平台前后径DMTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.8062,回归方程:DMTP=-11.9522+0.8341WTP;胫骨外侧平台前后径DLTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.8078,回归方程:DLTP=-11.6233+0.7992WTP。C组,胫骨内侧平台前后径DMTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.7234,回归方程:DMTP=-12.2436+0.8298WTP;胫骨外侧平台前后径DLTP与胫骨平台宽WTP存在线性关系(P0.05),相关系数:0.7529,回归方程:DLTP=-10.7347+0.7289WTP。胫骨截骨面横径/前后径比值(ML/AP):A组1.62-1.81,B组1.56-1.77,C组1.52-1.74,ML/AP均大于同尺寸进口假体比例。结论本研究测量并统计了国人病态膝关节胫骨平台的形态学尺寸,得出国人胫骨平台截骨面的横径与前后径比值大于西方人,在矮小的国人女性中更明显。本文建立了国人病态膝关节胫骨平台相关参数指标参考值,为人工膝关节假体的设计、制作提供了更加符合国人解剖结构的科学依据和参考价值。
[Abstract]:Objective to study the shape of Chinese tibial plateau and to obtain the anatomical parameters related to the osteotomy of the tibial plateau of Chinese knee joint, and to explore the guiding significance of this method in the design of the prosthesis. Methods from March 2005 to August 2006, 206 diseased knee joints of 168 patients who were hospitalized in arthrosurgery, Shanghai sixth people's Hospital, were all performed total knee arthroplasty for the first time. The tibial plateau parameters were measured directly during and after operation. The results of the statistical software SARS-7.0 were analyzed, the mean value and standard deviation were calculated, the correlation coefficients of the anteroposterior diameter and the width of the tibial plateau were given, and the regression equation was given. Results all 206 knees entered the result analysis. The proportional relationship between the parameters after tibial plateau osteotomy was established. Results according to the height of the patients, the patients were divided into group A and group B, and the regression equation was obtained. There was no statistical difference in each parameter between the three groups (P 0.05), and there was no statistical difference in the left and right knees (P 0.05). There was a linear relationship between the anteroposterior diameters of the medial tibial plateau and the width of the tibial plateau (WTP). The correlation coefficient was: 0: 0.8246, the regression equation was: DMTP- 11.8702 0.8341WTP, and the linear relationship between the anteroposterior diameters of the tibial platform and the width WTP of the tibial plateau was P0.05N, the correlation coefficient was 0.0.8478and the regression equation was: DLTP-10.6513 0.7197WTP.B. There was a linear relationship between the anteroposterior diameters of the medial tibial plateau (DMTP) and the width of the tibial plateau (WTP). The correlation coefficient was: 0: 0.8062, the regression equation was: DMTP- 11.9522 0.8341WTP; the linear relationship between the anteroposterior diameters of the tibial platform and the width of the tibial plateau was P0.05N, the correlation coefficient was 0.8078, and the regression equation was: DLTP-11.6233 0.7992WTP.C. There was a linear relationship between the anteroposterior diameters of the tibial plateau and the width of the tibial plateau WTP, the correlation coefficient was: 0: 0.7234, the regression equation was: DMTP- 12.2436 0.8298 WTP, and the linear relationship between the anteroposterior diameters of the tibial plateau and the width of the tibial plateau was P0.05, the correlation coefficient was 0.75299.The regression equation was DLTP- 10.7347 0.7289 WTP. The ratio of transverse diameter to anteroposterior diameter of tibial osteotomy was greater in group A than that in group A (1.62-1.81) and group B (1.56-1.77) and group C (1.52-1.74) was larger than that of imported prosthesis of the same size. Conclusion this study measured and counted the morphological dimensions of the tibial plateau of the diseased knee in Chinese. The ratio of transverse diameter to anteroposterior diameter of the osteotomy of the Chinese tibial plateau was higher than that of the westerners, especially in the short Chinese women. In this paper, the reference values of the parameters related to the tibial plateau of the diseased Chinese knee joint are established, which provide the scientific basis and reference value for the design and manufacture of the artificial knee joint prosthesis more in accordance with the anatomical structure of the Chinese people.
