Cortical Bone Trajectory Screw Fixation of Lumbar Spine in Adult Patients with Degenerative and Traumatic Spine Disorders

Abstract

Aim of the Work: to perform a systematic review and meta-analysis to determine whether traditional Pedicles Screw Fixation (PS Fx) or Cortical Bone Trajectory Screw Fixation (CBT Fx); has been successful for the treatment and fixation of lumbar spine in adult patients with degenerative and traumatic spine disorders; and to compare the 2 techniques to identify risk factor for unfavorable outcome through the recent researches about that issue. Methodology: this review was done using standard methodology outlined in the Cochrane Handbook and reported the findings in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement guidelines. Results: meta-analysis study showed that; 1. Successful fusion rate in fixed and random-effects models were (92.24% respectively); in SP group. 2. Successful fusion rate in fixed and random-effects models were (92.44% respectively); in CBT group. 3. Fixed and random-effects models showed non-significant difference in successful fusion rate; between the 2 groups of studies (p > 0.05). We calculated safety for each technique through post-operative (failed fusion rate)
