The Cortical Bone Trajectory: An Alternative to Traditional Pedicle Screw Fixation - A Review
نویسندگان
چکیده
The cortical based trajectory for pedicle screw fixation of the lumbar spine is not a novel as it once was. This is a review of the background, indications, advantages, disadvantages of cortical based trajectory pedicle screw fixation with an emphasis on biomechanical evidence and recent clinical studies which only now are just coming to light.

The Cortical Bone Trajectory for Pedicle Screw Insertion.
P edicle screw fixation for spinal stabilization is now commonplace in spine surgery. Traditionally, pedicle screws are placed through a trajectory in which screw insertion utilizes a transpedicular path through the axis of the pedicle, either paralleling the end plate, as in the straightforward trajectory, or following the anatomic axis of the pedicle with an approximately 22° cephalocaudal tr...
متن کاملThe "medio-latero-superior trajectory technique": an alternative cortical trajectory for pedicle fixation.
An alternative pedicle trajectory for use at the superior end of a construct to limit dissection of the mobile superior facet joint and reduce incision length and muscle dissection, thus minimizing approach-related trauma during pedicle fixation, is reported. The medio-latero-superior trajectory technique involves a starting point on the medial aspect of the pars and angulation of the pedicle s...
متن کاملCortical bone trajectory for lumbar pedicle screws.
BACKGROUND CONTEXT Achieving solid implant fixation to osteoporotic bone presents a clinical challenge. New techniques and devices are being designed to increase screw-bone purchase of pedicle screws in the lumbar spine via a novel cortical bone trajectory that may improve holding screw strength and minimize loosening. Preliminary clinical evidence suggests that this new trajectory provides scr...
متن کاملErratum to: A biomechanical comparison between cortical bone trajectory fixation and pedicle screw fixation
Erratum After publication of the original article [1] it came to our attention that the legends for figures 2 and 3 had been interchanged. The correct legend for figure two is 'Pedicle screw fusion model' and the correct legend for figure three is 'Cortical bone trajectory model'. biomechanical comparison between cortical bone trajectory fixation and pedicle screw fixation. permits unrestricted...
متن کاملReview of Cortical Bone Trajectory: Evidence of a New Technique
This article summarizes recent evidence on the cortical bone trajectory (CBT) obtained from published anatomical, biomechanical, and clinical studies. CBT was proposed by Santoni in 2009 as a new trajectory that can improve the fixation of pedicle screws in response to screw loosening in osteoporotic patients. Recently, research interest has been growing with increasing numbers of published ser...
