目的：系统地提供颈、胸、腰椎椎板厚度值，为临床应用提供参考资料。方法：对１００例原配完整的脊柱骨标本椎板厚度进行了形态学测量。结果：颈椎板（Ｃ１除外）Ｃ４、Ｃ５最薄，为３．０±０．７ｍｍ，Ｃ２最厚为６．４±１．２ｍｍ，呈明显中部薄两端厚的趋势；胸椎板Ｔ６最薄为６．５±０．９ｍｍ，Ｔ１２最厚为７．６±１．１ｍｍ，厚度变化不明显，平均值６．８±１．０ｍｍ；腰椎板Ｌ５最薄为６．０±１．１ｍｍ，Ｌ１、Ｌ２最厚为７．７±１．１ｍｍ，Ｌ１～Ｌ５呈明显由厚变薄趋势，Ｌ５大于Ｓ１椎管后壁厚度。椎板厚度左右侧差异无显著性（Ｐ＞０．０５），性别间差异Ｃ７～Ｌ３有显著性（Ｐ＜０．０５），同序数椎板厚度男性均大于女性。结论：脊柱椎板厚度有明显的规律性，Ｃ３～Ｃ６为最薄段，Ｃ４、Ｃ５最薄，Ｔ１２～Ｌ３为最厚段，Ｌ１、Ｌ２最厚；而胸椎板厚度（Ｔ１～Ｔ１１）介于颈、腰椎之间
Objective: To systematically provide the thickness of thoracic, thoracic and lumbar vertebral laminae and provide reference for clinical application. Methods: 100 cases of primary intact spine bone specimens were measured morphologically. Results: The C4 and C5 of the cervical laminae (except C1) were the thinnest at 3.0 ± 0.7mm and the C2 thickest at 6.4 ± 1.2mm 6.5 ± 0.9mm, the thickness of T12 was 7.6 ± 1.1mm, the thickness was not changed obviously, the average was 6.8 ± 1.0mm; the thinnest of L5 was 6.0 ± 1.1mm, L1, L2 thickest 7.7 ± 1.1mm, L1 ~ L5 was significantly thinning trend, L5 is greater than the posterior wall thickness of S1 spinal canal. There was no significant difference between the left and right sides of lamina thickness (P> 0.05). The difference of C7 ~ L3 was significant (P <0.05). Conclusions: The thickness of vertebral lamina has obvious regularity. C3 ~ C6 is the thinnest section, C4, C5 is the thinnest, T12 ~ L3 is the thickest section, and L1, L2 are the thickest. Between the neck and lumbar
