摘　　要：目的:为设计适合人体第5腰椎和骶椎三维解剖形态的腰骶前路内固定器提供相关解剖数据。方法:使用量具对人体腰5椎体和骶椎的有关径线进行测量,得出并比较相关参数的平均值及标准差。结果:腰5椎体前高为(26.2±2.5)mm;其不同平面之弦长(LLC2～LLC5)分别为(36.2±1.0)mm、(35.8±1.2)mm、(36.9±0.9)mm、(37.1±1.3)mm,其差异有统计学意义(P<0.01)。骶1椎体前高为(22.4±2.9)mm,其不同平面之弦长(SLC1～SLC5)分别为(36.2±1.5)mm、(38.2±0.9)mm、(38.8±0.9)mm、(38.7±1.5)mm、(39.0±1.4)mm,其差异有统计学意义(P<0.01)。结论:根据国人腰5椎体和骶椎的形态特点及相关参数,设计腰骶前路内固定器是可行的。Objective： To design Lumbosacral anterior internal fixation device suited for the three dimensional anatomic form of lumbosacral vertebrae. Methods：To measure some relative indexes of the fifth lumbar vertebrae and sacrum by soft ruler, then calculate their means and standard deviation. Results：The measurements of the fifth lumbar vertebrae showed that ： the mean lengths of line 6, chord 2,3,4,5 were （26.2 ±2.5 ） mm, （36.2 ±1.0） mm,（35.8 ±1.2） mm,（36.9 ±0.9 ）mm and （37.1 ±1.3） nun, respectively. The difference among the lengths of chord 2, 3, 4 and 5 had statistically significant （P 〈 0.01 ）. The findings of the Sacrum were as follows： the mean lengths of line 4, chord 1,2,3,4,5 were （22.4 ±2.9） mm,（36.2 ± 1.5） mm,（38.2 ±0. 9） mm, （38.8 ±0. 9） mm, （ 38.7 ± 1.5 ） mm and （ 39.0 ± 1.4） mm, respectively. There was significant difference among the lengths of chord 1,2,3,4 and 5（P 〈0.01 ）. Conclusion：It is feasible to design Lumbosacral anterior internal fixation device on the bases of anatomic characteristic and correlated parameters of Lumbosacral vertebrae.
