目的　从解剖学角度探讨颈椎一期后前路手术中后路取自体颈椎椎板作为前路椎体间植骨材料的可行性。  方法    选择60例健康志愿者行颈椎CT扫描（平扫+矢状位重建）。其中，男、女各30例，年龄25~40岁。测量C3~7两侧椎板与椎弓根交界点的连线长度、两侧椎板交汇点到此连线的距离，并计算两侧椎板所围成的三角形的面积，与目前临床上常用的颈椎椎间融合器（PEEK cage）进行比较。测量并比较C3~7各椎板高度与对应的椎间隙高度。  结果    C3~7两侧椎板所围成三角形面积均大于临床常用颈椎椎间融合器的理论融合面积，C3~7椎板高度均大于对应的椎间隙高度。  结论    从解剖学角度，颈椎椎板作为颈椎一期后前路手术中前路椎体间植骨材料是可行的。

Objective　To explore the feasibility of using autologous cervical laminae as bone graft in anterior cervical discectomy and fusion during one-staged posterior-anterior cervical surgery.　Methods　60 healthy volunteers underwent CT scans and sagittal reconstruction images of the cervical spine were obtained, including 30 males and 30 females, with the age ranging from 25 to 40 years old. The length of the line which connects the bilateral intersection points of cervical laminae and pedicle, and the distance from the junction of bilateral lamina to the line which was mentioned above were measured. Then, the area of the triangle composed by the bilateral laminae from C3 to C7 was calculated and compared with the area of a commonly used PEEK cage. The heights of the laminae from C3 to C7 were measured and compared with the corresponding intervertebral space heights.　Results　The area of the triangle composed by the bilateral laminae from C3 to C7 was greater than that of the PEEK cage. The heights of the laminae from C3 to C7 were greater than those of the corresponding intervertebral spaces.　Conclusion　According to the anatomical measurement of the cervical spine, adotpion of the autologous cervical laminae as bone graft in anterior cervical discectomy and fusion is feasible.
