Objective To study the methods of digital measurement of the morphology of posterior proximal tibia and to investigate the significance in the treatment of tibial plateau fractures. Methods Tomographic images of 60 healthy human tibial specimens were obtained by CT scans and imported into the Mimics 10.01 software for 3D reconstruction. Then the related anatomical parameters were measured and analyzed. Results The posterior central height was (8.46±1.62)mm, the posteromedial height was (12.27±1.93)mm, the posteromedial slope length was (14.71±2.27)mm, the posteromedial plateau-slope angle was (132.02±11.62)°, the posteromedial slope-diaphysis angle was (147.28±10.72)°, the posterolateral height was (11.31±1.74)mm, the posterolateral height was (14.45±2.26)mm, the posterolateral plateau-slope angle was (124.01±9.81)° and the posterolateral slope-diaphysis angle was (141.88±9.09)°. There were no statistically significant differences between different sides(P＞0.05). The Posterior central height, the posterolateral height and the posterolateral height were correlated to the total length of tibia(P＜0.01). Conclusion The three-dimensional reconstruction model has a high fidelity and a high accuracy in anatomical measurement. It can provide anatomical references in the clinical managements and implants designing of posterior tibial plateau fractures.
