Outcome of lumbar fusion with template-guided cortical bone trajectory versus traditional pedicle screw trajectory – a prospective randomized trial

Abstract Purpose Traditional trajectory (TT) pedicle screw fixation remains the reference standard for lumbar fusion. Cortical bone trajectory (CBT) screw placement has been proposed as a less invasive alternative with potential biomechanical advantages, but the technique is dema...
