“…Hung et al [ 45 ] measured fat infiltration after CBT or TT fixation by postoperative magnetic resonance imaging; they found no significant differences in clinical outcome or perioperative parameters, although minor postoperative blood loss, operative time, and hospital stay were reduced with CBT. Fat infiltration was higher with TT ( Table 3 ) [ 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 44 45 46 47 48 ].…”

“…Orita et al [ 46 ] described percutaneous CBT with better results measured with a VAS at 6 months compared to percutaneous TT, with a shorter time of fluoroscopy and skin incision. Ashayeri et al [ 47 ] used a hybrid technique for congenital multilevel spinal non-segmentation, concluding that CBT could improve pedicle screw fixation when bone quality was suboptimal or pedicle anatomy was distorted. Sakaura et al [ 48 ] compared CBT with PLIF versus TT with PLIF and concluded that the JOA were significantly better in the CBT group and that there were fewer cases of symptomatic adjacent-segment disease (three [3.2%] with CBT vs. nine [11%] with TT, p <0.05), with no differences in solid spinal fusion.…”

“…CBT has been shown to have applications for various pathologies, such as the double-fixation system [ 28 ], hybrid techniques for avoiding major exposure [ 33 ] or for congenital spinal deformation [ 47 ], treatment of adjacent segment disease [ 32 ], in combination with other techniques such as kyphoplasty [ 34 ], or the recently proposed percutaneous CBT [ 46 ]. However, these have been reported only as case studies and the indication has not been clearly elucidated.…”

Review 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 series and frequent reports of new applications. We performed an online database search using the terms “cortical bone trajectory,” “pedicle screw,” “CBT spine,” “CBT fixation,” “MISS CBT,” and “traditional trajectory.” The search included the PubMed, Ovid MEDLINE, Cochrane, and Google Scholar databases, resulting in an analysis of 42 articles in total. These covered three aspects of CBT research: anatomical studies, biomechanical parameters, and clinical cases or series. Compared to the traditional trajectory, CBT improves pullout strength, provides greater stiffness in cephalocaudal and mediolateral loading, and shows superior resistance to flexion/extension; however, it is inferior in lateral bending and axial rotation. CBT seems to provide better immediate implant stability. In clinical studies, CBT has shown better perioperative results for blood loss, length of stay in hospital, and surgery time; similar or better clinical postoperative scores; and similar comorbidity, without any major fixation system complications due to instrumentation failure or screw misplacement. In addition, advantages such as less lateral exposure allow it to be used as a minimally invasive technique. However, most of the clinical studies were retrospective case series or case-control studies; prospective evidence on this technique is scarce, making a definitive comparison with the traditional trajectory difficult. Nevertheless, we can conclude that CBT is a safe technique that offers good clinical results with similar biomechanical and perioperative parameters to those of the traditional trajectory. In addition, new applications can improve its results and make it useful for additional pathologies.

Emerging Techniques in Degenerative Thoracolumbar Surgery

et al. 2017

View full text Add to dashboard Cite

There continue to be incremental advances in thoracolumbar spine surgery techniques in attempts to achieve more predictable outcomes, minimize risk of complications, speed recovery, and minimize the costs of these interventions. This paper reviews recent literature with regard to emerging techniques of interest in the surgical treatment of lumbar spinal stenosis, fusion fixation and graft material, degenerative lumbar spondylolisthesis, and thoracolumbar deformity and sacroiliac joint degeneration. There continue to be advances in minimal access options in these areas, although robust outcome data are heterogeneous in its support. The evidence in support of sacroiliac fusion appears to be growing more robust in the properly selected patient.
