Pedicle Screws

09/01/2022 - "Numerous studies proved that all pedicle screw constructs produce the best outcome in the surgical treatment of patients with scoliosis. "
04/01/2013 - "Thoracic pedicle screw (TPS) constructs have improved curve correction measurements compared with hook and hybrid constructs in the treatment of adolescent idiopathic scoliosis (AIS), but the optimal implant density, or the number of screws per level, remains unknown in the treatment of flexible thoracic curves. "
10/01/1997 - "Lumbar pedicle screw instrumentation has proven to be reliable and effective in the surgical management of scoliosis. "
05/01/2021 - "In conclusion, posterior spinal fusion with high-density pedicle screw systems and direct vertebral rotation may be safe and effective in surgical correction of scoliosis in UCMD. "

04/01/2010 - "Iso-C3D based navigation has been reported to improve the accuracy of pedicle screw placement, however, there are very few studies assessing its efficacy in the presence of deformity. "
12/01/2005 - "Improved deformity correction and overall construct rigidity are two important advantages of pedicle screw instrumentation due its three-column control over the spinal elements. "
02/01/2014 - "We found that the application of posterior instrumentation using pedicle screw and rod resulted in a reasonable correction of the deformity with a significant reduction in recumbency-associated complications; the limiting factor being the small study group and short follow-up period."
01/01/2015 - "In 2013 Lykissas et al, reported that costoplasty combined with pedicle screws and vertebral derotation significantly improved RH deformity as opposed to pedicle screws and vertebral derotation alone. "
03/01/2014 - "The ability to combine 3D imaging with intraoperative navigation systems has improved the accuracy and safety of pedicle screw placement, especially in more complex spinal deformities. "

03/01/2022 - " VAS decreased gradually at 3 days,3 months,6 months and 12 months after operation,and the differences were statistically significant compared with the VAS before surgery (all P<0.01).ODI at 3,6 and 12 months after surgery was significantly improved compared with that before surgery(All P<0.01).The CT-related parameters at 3 days after operation were significantly higher than those before operation (All P<0.05).At 12 months after surgery,the Cobb angle decreased from (35.2±7.6) ° preoperatively to (4.3±1.7) ° (t=22.630,P<0.01),the height of anterior edge of diseased vertebrae increased from (4.3±1.0) mm preoperatively to (16.9±2.5) mm(t=-25.845,P<0.01),the bone mineral density of hip increased from -(2.2±0.6) preoperatively to -(2.8±0.6)(t=-0.040,P<0.01).Up to the last follow-up,2 patients had distal pedicle screw loosening, 1 patient had proximal junctional kyphosis,and there was no new vertebral fracture. "
02/01/2015 - "Pedicle screw constructs appear to provide better correction of coronal parameters than historically reported and provide significant improvement of sagittal kyphosis as well. "
06/15/2013 - "The all-pedicle screw group showed a significantly greater increase in thoracic kyphosis than the hybrid group system (P = 0.04). "
07/25/2019 - "Compared with traditional short-segment 4 pedicle screws fixation, intermediate bilateral or unilateral pedicle screw fixation were more effective in maintaining the height of the injuried vertebrae and preventing the occurrence of kyphosis. "
04/01/2010 - "Posterior short segmental pedicle screw fixation with pedicle screw at the fracture level is a safe and effective therapeutic option to treat thoracolumbar vertebral fractures, which can help to correct the kyphosis and maintain the reduction, and avoid the over-distraction of the contiguous discs."

06/01/2016 - "The authors conclude that transsacral transdiscal pedicle screws may serve as an efficacious and safe option for the correction of high-grade spondylolisthesis in adolescent patients. "
10/01/2013 - "Posterior lumbar interbody fusion with pedicle screws fixation, with or without intraoperative reduction, provides good outcomes in the surgical treatment of aged patients with degenerative spondylolisthesis. "
05/25/2022 - "The MIS-TLIF assisted by microscope and the MIS-TLIF combined with percutaneous pedicle screw are safe and effective to treat the degenerative lumbar spondylolisthesis with single-segment, and the MIS-TLIF assisted by microscope may be more invasive, cause less blood loss and achieve better clinical efficacy."
08/01/2019 - "Overall, MIS-TLIF combined with the fenestrated pedicle screws is an effective and safe technique for the treatment of spondylolisthesis with osteoporotic spine."
02/25/2017 - "Single cage interbody fusion combined with pedicle screw fixation is as effective as with double cages interbody fusion in treatment of isthmic spondylolisthesis, it has the advantages of short operative time and less blood loss."

01/01/2008 - "Posterior pedicle screw/rod dynamic stabilization using the NFix II System seems very effective in improving pain and function scores, at least in the short term (mean postoperative ODI of 22.8). "
07/01/2017 - "The application of a drill guide template for pedicle screw placement is not more effective in reducing pain and disability after midterm follow-up in comparison with the free-hand technique. "
01/01/2020 - "Results from this study suggest that, 13 years after pedicle screw fixation with BAER and cement injection for traumatic thoracolumbar burst fractures, functional performance, pain and radiological outcomes of the current cohort were stable or had slightly improved. "
06/01/2006 - "Spinal reconstruction using cervical pedicle screws improved spinal stability, pain, and neurologic function. "
03/14/2021 - "A systematic literature review was conducted on studies comparing interspinous process (ISP) devices to traditional methods of posterior spinal instrumentation (pedicle screw-rod construct), in terms of indications of use, complications, pain assessment, estimated blood loss, length of hospital stay, reoperation rates, and return to work.
