Real-world clinical accuracy of long cortical bone trajectory screw placement using a patient-specific template guide.

ABSTRACT:

Background

Cortical bone trajectory (CBT) screws can be very reliable anchors if inserted precisely anterior to the vertebral body; however, their trajectory is narrow, and malpositioning of the screw is not rare, especially for surgeons who are not familiar with the CBT screw. Patient-specific template guides are a solution to this problem; however, their accuracy and usefulness in clinical settings remain unclear. The aim of the present study was to evaluate the accuracy of long CBT placement using a patient-specific screw-guide system.

Methods

This research involved a retrospective clinical evaluation of patients who had been enrolled prospectively. One hundred consecutive patients who underwent posterior lumbar spinal fusion using the guide system performed by three expe
