Abstract:
BACKGROUND:In the process of designing knee joint prosthesis and operating total knee arthroplasty for the Chinese people, we should not only take into account the proximal tibial anatomical characteristics and the difference of geometry, but also should pay attention to the differences between different races. OBJECTIVE:To compare the anatomical morphological differences between Mongolian and Han nationality through measuring the CT tomography scanning and three-dimensional reconstruction measurement of tibia proximal part of Han and Mongolian nationality, so as to provide the data references for prosthesis selection used for total knee arthroplasty. METHODS:Total y 60 patients who received the treatment at the Department of Joint Surgery were col ected, and divided into Han nationality and Mongolian nationality groups (n=30/group, 15 males and 15 females in each group). The age was (36.00+7.22) years old. 16-row helical CT scan (American GE Lightspeed 16) was used for spiral scanning, slice thickness 0.625 mm. Scanning images were exported in DICOM format and saved. Digital three-dimensional reconstruction measurement was conducted using Mimics 15.0 three-dimensional reconstruction software. The tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter were measured respectively to observe whether there were any differences among sex, sides and nationality. RESULTS AND CONCLUSION:There were no significant differences in the above indicators between left and right sides (P>0.05). There were significant differences in tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter between males and females, and Han and Mongolian nationality groups (P<0.05). Specific performed in:(1) There was significant difference in the morphological measurement parameters of proximal tibia between sex for Han and Mongolian nationality, and the mean value of male was larger compared with that of female. (2) There was certain significant difference in the part of the parameter indicators between Han and Mongolian nationality groups. These results suggest that the prosthesis should be chose and placed correctly according to the differences of morphological characteristics, gender, nationality, region of the Chinese people. (3) Digital three-dimensional reconstruction technology and individualized design can choose suitable prosthesis for different people, so as to ensure a good repair effect in patients after total knee replacement.
