Abstract:

BACKGROUND: Lower cervical pedicle screw has greater biomechanical strength, higher level of three-dimensional stability and fusion rate of bone graft. However, because the cervical anatomical structure is complicated and has great individual difference, it often leads to screw placement difficulty and surgical risk.
OBJECTIVE: Using the picture archiving and communication systems (PACS) combined with 64-slice Helice CT film and X-ray preoperative accurate measurement of cervical rear anatomy structure, to guide the implantation of the cervical pedicle.
METHODS: A retrospective review in 51 patients with lower cervical disease was operated suing the PACS measurement localization method with cervical vertebral pedicle internal fixation. Meanwhile, two different cervical vertebral pedicle screw internal fixation of surgery patients were collected for statistics analysis during the same period: (1) Anatomy set of screws method in 26 cases, (2)Pipeline dredge method in 17 cases. All research data above were assessed based on Andrew Scoring System. The practical application and clinical effect were compared using statistical method.
RESULTS AND CONCLUSION: The accurate rate for screw location by using PACS measurement localization method was higher than that in the other two groups (P < 0.05). The patients in the PACS measurement localization group had no spinal cord injury, vertebral artery damage, nerve injury, etc. Using the PACS combined with 64-slice Helice CT film and X-ray preoperative accurate measurement of cervical rear anatomy structure before operation can be able to guide the security of implantation of cervical pedicle screws in the operation. Its clinical effect is obviously better than the traditional methods as anatomy set of screws method and pipeline dredge method.
