摘要:

背景:详细了解国人的膝关节形态,从而实现国人个性化、性别差异化全膝关节置换,并设计研究符合国人特征的膝关节假体,已越来越受到业界关注。
目的:通过CT断层扫描及三维重建测量正常成年国人股骨远端的解剖形态并比较其性别差异。
方法:对70名正常成年国人双侧膝关节行CT扫描,男、女各35名,年龄21-60岁,通过三维重建或使用Picasa 3.0图像处理软件对其进行拼贴及重叠曝光等处理。在经过处理的图像上分别测量股骨远端前髁角、后髁角、滑车沟角的大小,股骨远端横径与外侧髁高度及两者之间的比值。
结果与结论:①国人股骨远端后髁角女性大于男性(P < 0.05);国人股骨远端前髁角男性大于女性(P < 0.05);国人滑车沟角性别间无明显差异。②国人男性的股骨远端横径、股骨远端外侧髁高度及股骨面率(横径/外上髁高度)均大于女性(P < 0.05)。结果可见国人股骨远端的形态与西方人种不同,存在性别差异。在全膝关节置换中假体的选择及其放置、股骨远端假体在设计时应体现出这些差异,使之与国人的膝关节形态相匹配。

Abstract:

BACKGROUND: It has become increasingly concerned by the industry to detailed understand the morphology of people’s knee joint, thus achieving personalized and gender differentiated total knee arthroplasty, in order to design the knee joint prosthesis that match the characteristics of Chinese people.
OBJECTIVE: To measure and characterize the morphological parameters of distal femur of normal adult Chinese people by CT tomography and three-dimensional reconstruction, and to discuss the differences between male and female in morphology of distal femur.
METHODS: Seventy normal Chinese adults (35 males and 35 females, aging from 21 to 60 years) received bilateral knee joint CT scan. The scanning images of distal femur which we needed were collected and handled with three-dimensional reconstruction or Picasa 3.0 software for collages and overlapping exposure. The posterior condylar angle, anterior condylar angle and trochlear angle were measured on the images that treated by the software, as well as the transverse diameter of distal femur, lateral condylar height, and the ratio between them.
RESULTS AND CONCLUSION: The mean posterior condylar angle of Chinese women was larger than that of Chinese men (P < 0.05); the mean anterior condylar angle of Chinese men was larger than that of Chinese women (P < 0.05); The transverse diameter of distal femur, lateral condylar height and the femoral surface ratio (diameter/epicondyle height) of Chinese men were larger than those of Chinese women (P < 0.05). The results showed that differences exist in morphology of distal femur between Chinese and western people. Also, the differences exist between male and female in Chinese people. These differences should be concerned in the design of femoral prosthesis for Chinese people as well as in selecting and placing of femoral prosthesis before or during the total knee arthroplasty.
