In posterior C1/C2 fusion using lateral mass screws (LMS) or pedicle screws (PS), screw stability is predominantly determined by cortical contact length and bone volume. The study authors analyzed 28 ...

2.2.1.4 Cortical bone trajectory (CBT) model. Conversely, in the CBT model, screws were positioned following an ideal cortical bone trajectory as described by Matsukawa et al. (Matsukawa et al., 2015a ...

Introduction : Midline lumbar fusion (MIDLF) using cortical bone trajectory is an alternative method of transpedicular spinal fusion for degenerative disease. The new entry points’ location and ...

Introduction. Cortical bone trajectory (CBT) was a new lumbar screw trajectory proposed by Santoni in 2009 ().Compared with the traditional pedicle screw trajectory, CBT increases the contact surface ...

Evaluate the mechanical competence of lumbar pedicle screws using a more medial-to-lateral path (ie, "cortical bone trajectory") than the traditionally used path. Human cadaveric biomechanical study.

Screw insertion point selection. Without changing the horizontal axis, the vertical axis of the insertion point of the cortical bone screw was moved from the conventional mid-perpendicular line of the ...

In patients with thoracolumbar ankylosing spondylitis (AS) fracture fixation, use of the transpedicular screw (TPS) compared with the cortical bone trajectory (CBT) technique provided better ...
