Morphometric Analysis and Three-Dimensional Computed Tomography Reconstruction of Thai Distal Femur

This study evaluates the distal femur morphology of Thai population using a three-dimensional (3D) measurement method, measuring distance between triangular point femoral 3D model. The model 360 obtained from 180 volunteers (90 males, 90 females; range 20–50 years, average 32.8 years) was created reverse engineering techniques computed tomography imaging data. Using identified landmark morphometric parameters evaluated included transepicondylar axis length (TEA), mediolateral (ML), anteroposterior width (AP), medial (MAP), lateral (LAP), condyle (MCW), (LCW), intercondylar notch (WIN), depth (DIN), posterior height (MPC), (LPC), aspect ratio (ML/AP), (ML/LAP), and (ML/MAP). measured data were summarized for analysis an value standard deviation. Statistical performed independent samples t-test, unequal variances linear regression. A p-value less than 0.05 (<0.05) regarded as statistically significant indicates strong evidence hypothesis. Additionally, K-means clustering to optimum size prosthesis with correlation ML AP performed. results found that male significantly different higher those females, except ML/AP ML/MAP. Comparatively, there difference specific Korean population, which also smaller Caucasians. In addition, mismatch component sizing knee what is available commonly used in Thailand. At least six sizes and/or should be recommended reasonable design covering anatomy Thais. These are useful predicting forensic anthropology provide basic prostheses suitable population.
