对50例年龄在20 ~ 40岁之间的正常成人脊柱的多种形态学参数进行了研究。后元件形态是高度可变的，很大程度上是不可预测的。最小椎弓根直径范围为T6的1.8 mm至L5的6.4 mm，并且与任何更容易测量的椎骨尺寸无关。预计5 mm螺钉螺纹穿透椎弓根皮质通常发生在下胸椎，以及较少但数量可观的腰椎。
Multiple morphologic parameters were studied in 50 normal adult vertebral columns ranging in age from 20 to 40 years at the time of death. Posterior element morphology is highly variable and largely unpredictable. Minimum pedicle diameters ranged from 1.8 mm at T6 to 6.4 mm at L5, and did not correlate with any more readily measured vertebral dimensions. Penetration of 5 mm screw threads through pedicle cortex can be expected to occur routinely in the lower thoracic spine, and in a lesser but significant number of lumbar vertebrae.
