中国福建东南部成人女性胫骨近端表面及断面几何参数三维数字化测量及临床意义
Three-dimensional digital measurement and clinical significance of geometric parameters on proximal tibial surface and cross-section of adult women in southeastern area of Fujian province of China
摘要
Abstract
BACKGROUND:Artificial knee joint replacement is the main surgical method for the treatment of severe knee joint deformation, but due to the limited existing knee prosthesis type. The stature of Fujian population in southeast China was shorter than that of the north. The size of artificial knee joint usual y did not fit for patients in clinic. The substitution effect was poor. <br> OBJECTIVE:To measure the geometric parameters of proximal surface and cross-section of adult female tibia in southeastern area of Fujian Province of China, and provide basic data for design and replacement of artificial knee joint in females. <br> METHODS:We chose 85 cases of dry female skeleton in southeastern area of Fujian Province of China, measured tibial plateau width, medial tibial plateau width and anteroposterior diameter, lateral tibial plateau width and anteroposterior diameter. We col ected clinical normal proximal tibial CT data of 36 patients (38-65 years old), with scan range of 30 cm (intercondylar eminence 30 cm) and layer thickness of 0.625 mm. Mimics 16.0 three-dimensional reconstruction software was used to measure above indexes and cut the reconstructed models with thickness of 3 mm, total y 10 layers. We divided its widest distance into four equal parts, and measured tibial anteroposterior diameter on three points. Statistical software was used to analyze the linear relationship between the data. <br> RESULTS AND CONCLUSION:The experiment has successful y obtained geometric parameters of tibial specimens of adult females in southeastern area of Fujian province of China. Tibia platform inside and outside diameters were greater than the width inside and outside;inside and outside diameter and inside and outside width were similar. Ten segment planes of tibia, inside and outside diameters were always less than middle anteroposterior diameter. Three groups of data increased firstly, and then reduced. There were positive correlations between tibia length and width of the medial tibia platform, the lateral tibia platform width and anteroposterior diameter, the medial tibia platform width and anteroposterior diameter, and the lateral tibia platform width and anteroposterior diameter (P<0.05). These results suggested that relevant parameters of tibial plateau adult women in southeastern area of Fujian province of China showed some regular changes. Our results may provide quantitative reference data for the design and operation of artificial tibial plateau.关键词
