Anatomical morphology study of cervical laminae as bone graft in anterior cervical discectomy and fusion
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.
