Abstract:

Abstract: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.Results 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.
