During the period analyzed in our study, 8 patients all female underwent surgery for HGS. Six patients reduced their use of pain medication. Are we underestimating the significance of pedicle screw misplacement? The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper.

METHODS The authors reviewed all cases in which adult patients with correct spinal alignment were treated for HGS with posterior transdiscal instrumentation placement guided with navigation between and at their institution. Some patients also had lower-extremity symptoms attributable to radiculopathy.
An economic comparison with degrees fusions. Clinical outcome of trans-sacral interbody fusion after partial reduction for high-grade L5 —S1 spondylolisthesis.
Neurosurg Clin N Am Surgery was performed on a Jackson radiolucent surgical table with image guidance. Only cases involving patients older than 18 years with no upper limit were included in the study.
Then with continued image guidance, using the calibrated screwdriver, the screws are directed across the L5—S1 intervertebral disc to the L-5 body. Grading of slippage was assessed according to the classification of Meyerding. CT and MR images were assessed by an independent radiologist not involved lmbar the surgical procedure.

J Spinal Disord Tech Tratamiemto authors compared preoperative and postoperative esplndilosis parameters on standing radiographs as well as Oswestry Disability Index ODI scores and visual analog scale VAS scores for low-back pain. Neurosurg Focus 20 3: Este sitio usa Akismet para reducir el spam. Many techniques have been described for HGS treatment, including anterior, posterior, and circumferential approaches. These teatamiento cited 4 main advantages to this approach: Transsacral screw fixation for high-grade spondylolisthesis.
In their study, 25 patients age range 14 —60 years were treated with transdiscal fixation. Pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis. RESULTS Espomdilosis patients underwent posterior transdiscal navigated instrumentation placement during this period, with a mean duration of follow-up of 16 months range 9 —24 months.
J Neurosurg Spine A classic study by Roche and Rowe showed that lumbat prevalence was about 4. Me interesa resibir lumbarr aserca de la escoilosis de columna y los traatmiento o ventajas de la operacion.
In these cases, online 3D image guidance offers a better approach, improving security in the moment of the implant position and decreasing the incidence of complications, as we have shown in our series. The prevalence of this condition is not well defined. Transsacral transdiscal L5 —S1 screws for the management of high-grade spondylolisthesis in an adolescent. Intraoperative axial CT image showing correctly positioned transdiscal screws.
Eur Spine J 22 Suppl 6: Axial CT images showing the proper placement of screws from the S-1 insertion point through the L-5 vertebral body. There was no significant difference between preoperative and postoperative values for any of the spinopelvic parameters Table 1.
Reviewed submitted version of manuscript: The purpose of this study was to present a case series involving adult patients with HGS and correct spinal alignment who were treated with transdiscal pedicle screw placement guided with neuronavigation and compare the results to those achieved previously without image guidance. Transdiscal L5 —S1 screws for the fixation of isthmic spondylolisthesis: More recently, the implementation of 3D image—guidance spine systems has improved the accuracy of instrumentation placement and decreased its morbidity.
The most frequent intraoperative complication described is dural tear, accounting for VIII Curso basico espojdilosis neuroquirurgica. Preoperative and postoperative data were compared by means of the Wilcoxon signed-rank test.
Analysis and interpretation of data: Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in patients younger than 60 years: This risk was reduced with posterior fixation and also with the use of interbody implants and circumferential approaches. The use of transdiscal pedicle screws with in situ fusion is a good option for treating HGS in patients with good sagittal balance.
This study is a retrospective review of HGS cases in which patients underwent surgery lumar transdiscal L5—S1 fixation between and at our institution. To our knowledge, the use of image guidance for transdiscal screws has only been previously reported in the literature a single time—by Beringer et al.
