Cortical Bone Screw

Novel lumbar pedicle screw path

The CBT technique maximizes thread contact with the cortical bone surface and provides increased fixation strength, which may improve holding screw strength and minimize loosening.

The CBT technique follows a medial-to-lateral path in the transverse plane and a caudal-to-cephalad path in the sagittal plane through the pedicle.
