The lumbar interbody fusion using cortical bone trajectory pedicle screws: clinical results of the lumbar degenerative spondylosis surgical treatment

Abstract

Introduction. The Midline lumbar interbody fusion (MIDLIF) uses the cortical bone trajectory (CBT) pedicle screws instead of the traditional pedicle screws. The CBT screw follows a medial to lateral path in the transverse plane and is tilted caudally in the sagittal plane. This technique is minimally invasive, reinforces the screw pullout strength and reduces the approach-related morbidity.
