Objective To investigate the lumbar vertebrae parameters of deer, sheep and human via anatomy appearance and curvature in animal models, and explore the posibility of deer and sheep as vertebrae model. Methods 30 fresh samples of deer, sheep, human vertebrae were chosen. SPSS 17.0 software was used to statistically analyze the data get from sliding caliper and CT. ResuJts The forward, middle, behind heights of human vertebrae were 25.76, 21.08 and 26.3 mm, in deer they were 37.75, 41.10 and 42.72 mm, in sheep they were 31.24, 32.70 and 33.78 mm. The upper, middle, inferior diameters of human vertebrae were 49.91, 44.26, and 52.85 mm, in deer they were 28.04, 23.51 and 32.82 mm, in sheep they were 24.52, 21.44 and 28.12 mm. The upper, middle, inferior radius of human vertebrae were 36.42, 32.43 and 36.48 mm, in deer they were 23.07, 16.71 and 21.09 mm, in sheep they were 16.92, 12.96 and 16.87 mm. The vertebral foramens in coronal radius and sagittal radius in human were 23.40 and 15.62 mm, in deer they were 16.10 and 12.31 mm, in sheep they were 14.05 and 9.13 mm. The pedicle of vertebral arch in heigh and width in human were 15.72 and 13.78 mm, in deer they were 15.72 and 13.78 mm, in sheep they were 24.97 and 6.80 mm. The upper, inferior, middle curvature radius in human were 2.76, 23.78 and 19.98 mm, in deer they were 22.26, 23.27 and 32.91 mm, in sheep tyey were 15.37, 16.89 and 27.48 mm. The curvature radius coronal and sagittal in human were 22.83 and 39.57 mm, in deer they were 27.48 and 21. 49 mm, in sheep they were 21.70 and 24.03 mm. Conclusion The vertebrae and vertebral foramen of deer have similarity at length, width, curvature, lamina of vertebral arch with human being. The height of vertebrae, pedicle of vertebral arch, radius of curvature of sheep have similarity with human being. The vertebrae of deer and sheep have similarity at morphometry with human being, the vertebrae of deer is better used as a model at pedicle of vertebral arch, the vertebrae of sheep is better used as a model at vertebrae lateral wall.
