摘要
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。
Objective:To provide systematically the theoretical data on thickness of vertebral laminae of cervical,thoracic and lumbar vertebral for clinical application.Methods:The measurements of vertebral laminae were carried out on 100 originally spinal specimens.Results:In cervical vertebral laminae (not including C 1),both C 4 and C 5 were the thinnest with the thickness of 3.0±0.7 mm,and C 2 was the thickest,6.4±1.2 mm.It showed the tendency of being thin in the center but thick on both ends.In thoracic vertebral laminae,the thinnest was T 6,6.5±0.9 mm,and the thickest was T 12 , 7.6 ± 1.1 mm,the thickness averaged 6.8±1.0 mm with no obvious variation.As for lumbar vertebral laminae,L 5 was the thinnest with the thickness of 6.0±1.1 mm while L 1 and L 2 were the thickest,7.7±101 mm.From L 1 to L 5,it could be found a clear tendency of change from thick to thin.In the light of thickness of vertebral laminae,S 1<L 5.There were no significant differences between the laminae on both sides( P >0.05),while there were differences between the sex in C 7 L 3 (P <0.05) and the numerical value from male group was greater than that from female group.Conclusions:There was a clear regularity in the thickness of vertebral laminae.The cervical vertebral(C 3～C 6) was the thinnest section while T 12 L 3 was the thickest section,of which the vertebral laminae of C 4 and C 5 were the thinnest and that of L 2 was the thickest.The thickness of the thoracic vertebral laminae was between those of cervical and lumbar vertebral laminae.
