<p><strong>Background:</strong> Aim of the study was to evaluate the effectiveness between percutaneous and open pedicle screw fixation in the treatment of traumatic thoracolumbar burst fractures with spinal injury.</p><p><strong>Methods:</strong> A prospective comparative study including thirty patients with thoracolumbar burst fracture were equally divided into an open pedicle screw fixation (OPSF) group and a percutaneous pedicle screw fixation (PPSF) group. Demographic characteristics, clinical and radiological outcomes, and adverse events were assessed and compared between the 2 groups.</p><p><strong>Results:</strong> Demographic and clinical features including age, gender, fracture level, mechanism of injury and neurological status in both groups were not significantly different (all p&gt;0.05). The PPSF group exhibits significantly lower operative time, intraoperative blood loss, and hospital stay compared with the OPSF group (all p&lt;0.05). There was no significant difference in the sagittal Cobb′s angle (CA), fracture vertebral body angle (VBA), anterior vertebral body height (AVBH) on pre-operative, immediate post-operative and final follow up between the two surgical techniques (all p&gt;0.05). Visual analogue scale (VAS) remarkably decreased in both groups after surgery but difference was not statically significant (p=0.808). Common postoperative complications in both groups were superficial infections, pressure ulcer and urinary tract infection (UTI) worsening. Hardware failure was seen only in one case of PPSF group.</p><p><strong>Conclusions:</strong> Patients with thoracolumbar burst fractures can be effectively managed with PPSF/OPSF. There were no significant differences in radiological and clinical outcomes and post-op complications between 2 groups but blood loss, operative time and hospitalization stay were less in percutaneous group, which may represent a potential benefit.</p><p><strong> </strong></p>

<p>Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fixation of more segments could improve clinical and radiological outcomes. This meta-analysis was performed to evaluate the effectiveness of fixation levels with pedicle screw fixation for thoracolumbar burst fractures. MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Springer, and Google Scholar were searched for relevant randomized and quasirandomized controlled trials that compared the clinical and radiological efficacy of short versus long segment for thoracolumbar burst fractures managed by posterior pedicle screw fixation. Risk of bias in included studies was assessed using the Cochrane Risk of Bias tool. Based on predefined inclusion criteria, Nine eligible trials with a total of 365 patients were included in this meta-analysis. Results were expressed as risk difference for dichotomous outcomes and standard mean difference for continuous outcomes with 95% confidence interval. Baseline characteristics were similar between the short and long segment fixation groups. No significant difference was identified between the two groups regarding radiological outcome, functional outcome, neurologic improvement, and implant failure rate. The results of this meta-analysis suggested that extension of fixation was not necessary when thoracolumbar burst fracture was treated by posterior pedicle screw fixation. More randomized controlled trials with high quality are still needed in the future.</p>

Percutaneous Pedicle Screw Fixation

Percutaneous pedicle screw fixation (PPSF) is a well-known minimally invasive surgery (MIS) employed in the treatment of thoracolumbar burst fractures (TBF). However, hardware failure and loss of angular correction are common limitations caused by the poor support of the anterior column of the spine. Balloon kyphoplasty (KP) is another MIS that was successfully used in the treatment of compression fractures by augmenting the injured vertebral body with cement. To overcome the limitations of stand-alone PPSF, it was suggested to augment PPSF with KP as a surgical treatment of TBF. Yet, little is known about the biomechanical alteration occurred to the spine after performing such procedure. The objective of this study was to evaluate and compare the immediate post-operative biomechanical performance of stand-alone PPSF, stand-alone-KP, and KP-augmented PPSF procedures. Novel three-dimensional (3D) finite element (FE) models of the thoracolumbar junction that describes the fractured spine and the three investigated procedures were developed and tested under mechanical loading conditions. The spinal stiffness, stresses at the implanted hardware, and the intradiscal pressure at the upper and lower segments were measured and compared. The results showed no major differences in the measured parameters between stand-alone PPSF and KP-augmented PPSF procedures, and demonstrated that the stand-alone KP may restore the stiffness of the intact spine. Accordingly, there was no immediate post-operative biomechanical advantage in augmenting PPSF with KP when compared to stand-alone PPSF, and fatigue testing may be required to evaluate the long-term biomechanical performance of such procedures.

Abstract Objectives Most common surgical intervention in thoracolumbar fracture is pedicle screw fixation with posterior decompression through traditional posterior approach. Nowadays, we are doing combined anteroposterior decompression with anteroposterior fixation through posterior only approach. So, we attempt to compare these two approaches in terms of surgical and functional outcome. Method This is a retrospective study. We included 47 patients of traumatic thoracolumbar fracture between September 2016 and January 2018. Fourteen patients were treated by three-column fixation through posterior only approach and 33 patients were treated with traditional posterior approach. In three-column fixation, transpedicular corpectomy with dynamic mesh cage placement with B/L pedicle screw fixation with 360 canal decompression was done, whereas in traditional posterior approach, only posterior decompression with B/L pedicle screw fixation was done. Parameters for comparison include patients’ parameters, fracture types, operative duration, average blood loss, kyphotic correction, and neurological and functional improvement after 1 week and 3 months postoperatively. Result The average operative time (150 ± 13.01 minutes) and blood loss (263 ± 40.84 mL) in combined decompression and fixation through posterior only approach were higher than average operative time (120.3 ± 25.43 minutes) and average blood loss (108 ± 27.32 mL) in traditional posterior approach. In traditional surgeries, there was an observed correction of 11.7° ± 3.6° in kyphosis, while in combined surgeries the observed correction in kyphosis was 15.3° ± 4.3°. There is no statistically significant neurological and functional outcome than traditional posterior approach. Conclusion Combined anteroposterior decompression and stabilization through posterior only approach is convenient for complete decompression of cord, stabilization, and restoration of vertebral height, and there is statistically significant kyphotic correction, pain relief (visual analogue scale), but there is no statistically significant neurological and functional outcome than traditional posterior approach. Most neurosurgeons are familiar to posterior approach; hence, they should be used in unstable thoracolumbar fracture whenever needed, while avoiding various dreaded complication of combined approach.

Abstract Background The management of thoracolumbar burst fractures traditionally involves posterior pedicle screw fixation, but it has some drawbacks. The aim of this study is to evaluate the clinical and radiological outcomes of patients with thoracolumbar burst fractures. They were treated by a modified technique that monoaxial pedicle screws instrumentation and distraction-compression technology assisted end plate reduction. Methods From March 2014 to February 2016, a retrospective study including 42 consecutive patients with thoracolumbar burst fractures was performed. The patients had undergone posterior reduction and instrumentation with monoaxial pedicle screws. The fractured vertebrae were also inserted screws as a push point. The distraction -compression technology was used as assisting end plate reduction. All patients were followed up at a minimum of 2 years. These parameters including segmental kyphosis, severity of fracture, neurological function, canal compromise and back pain were evaluated in preoperatively, postoperatively and at the final follow-up. Results The average follow-up period was 28.9 ± 4.3 months (range, 24-39mo). No patients had postoperative implant failure at recent follow-up. The mean Cobb angle of the kyphosis was improved from 14.2°to 1.1° (correction rate 92.1%). At final follow-up there was 1.5% loss of correction. The mean preoperative wedge angle was improved from 17.1 ± 7.9°to 4.4 ± 3.7°(correction rate 74.3%). The mean anterior and posterior vertebral height also showed significant improvements postoperatively, which were maintained at the final follow-up(P < 0.05). The mean visual analogue scale (VAS) scores was 8 and 1.6 in preoperation and at the last follow-up, and there was significant difference (p < 0.05). Conclusion Based on our experience, distraction-compression technology can assist reduction of collapsed endplate directly. Satisfactory fracture reduction and correction of segmental kyphosis can be achieved and maintained with the use of monoaxial pedicle screw fixation including the fractured vertebra. It may be a good treatment approach for thoracolumbar burst fractures.
