ABSTRACT Objective: To determine the effectiveness of surgical treatment of patients with idiopathic scoliosis who have severe spinal deformity, using either all pedicle screw or hybrid constructs. Methods: A retrospective analysis of the results of treatment of 34 patients aged 15 to 27 years with severe scoliosis, operated on using pedicle screws. A comparison group consisted of 22 patients who were operated on using hybrid constructs. Patients from both groups were compared according to the following parameters: pre/postoperative Cobb angle, mobility according to the traction test, global sagittal/frontal balance, apical vertebral rotation, operative time, intraoperative blood loss, number of instrumented vertebrae, and loss of correction within 24 months. Results: In group A (pedicle screw fixation) compared to group B (hybrid spinal fixation), patients had better results in the following parameters: postoperative correction was 48% and 41%, apical vertebral rotation decreased from 78° to 55° (30%) and from 74° to 59° (21%), correction of global frontal/sagittal balance from 39/25 mm to 14/12 mm (64%/52%) and 35/26 mm to 16/15 mm (55%/43%) between treatment groups, respectively. These results suggest a better trunk balance and greater postoperative correction in patients submitted to the all pedicle screw fixation. Smaller values were found for loss of correction of the major curve, and there was a slight increase in thoracic kyphosis in the postoperative period (24 months) 3.8%/4.3% in group A vs. 6.2%/7.5% in group B, indicating greater reliability and stability of the metal with the «all screw» fixation. This was a Level III retrospective comparative study. Conclusion: All the pedicle screw constructs enabled better postoperative correction, derotation, global sagittal and frontal balance, as well as a shorter fixation, compared to hybrid fixation of the spine. Level of Evidence III, Retrospective comparative study.

Prospective Comparative Study

<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>
