Radiological Evaluation of the Initial Fixation between Cortical Bone Trajectory and Conventional Pedicle Screw Technique for Lumbar Degenerative Spondylolisthesis
STUDY DESIGN Retrospective study. PURPOSE To compare initial fixation using the cortical bone trajectory (CBT) technique versus conventional pedicle screws (PS) in radiographs of postsurgical lumbar degenerative spondylolisthesis. OVERVIEW OF LITERATURE Few reports have documented the holding strength of CBT technique for spondylolisthesis cases. METHODS From October 2009 to June 2014, 21...
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...
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 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 کاملA biomechanical comparison between cortical bone trajectory fixation and pedicle screw fixation
PURPOSE There have been several reports on the pullout strength of cortical bone trajectory (CBT) screws, but only one study has reviewed the stability of functional spine units using the CBT method. The purpose of this study was to compare vertebral stability after CBT fixation with that after pedicle screw (PS) fixation. METHODS In this study, 20 lumbar spine (L5-6) specimens were assigned ...
