This study is a retrospective review of HGS cases in which patients underwent surgery with transdiscal L5—S1 fixation between and at our institution.

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. Intraoperative photograph showing the use of a navigated awl-tap for transdiscal screw placement. As Collados-Maestre et al. Acta Orthop Belg Clin Orthop Relat Res Also, none of the patients required a transfusion after the procedure.

Nonetheless, the main limitation in our study is a short mean duration of followup, and this may have led to underestimation of implant failure and the presence of pseudarthrosis as well as the fusion rate in the most recent cases.

No reduction of the listhesis was performed in any case, as there was no spinal imbalance. Pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis. 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.

In addition, standing anteroposterior and lateral lumbosacral radiographs and lateral flexion-extension images, together with full spine standing lateral radiographs for tratamjento and pelvic ljmbar, were obtained in every case. Operative management of adult high-grade lumbosacral spondylolisthesis.

lunbar VIII Curso basico tecnica neuroquirurgica. Our results presented here further demonstrate that screw malplacement and hardware breakage are greatly reduced with the use of online 3D image guidance compared with the results from previous reports.

A classic study by Roche and Rowe showed that the prevalence was about 4.

Low-back pain lasting longer than 2 years was the main symptom in all the cases, radiating to the lower extremities mainly at the pelvic girdle.

The mean duration espondiloxis follow-up was 16 months range 9—24 monthsand no complication was observed during this period. After calibration of the probe, tap, and screwdriver Fig. Reviewed submitted version of manuscript: J Neurosurg Pediatr XVI Simposium internacional hernia discal cervical, dorsal y lumbar.

Spondylolisthesis, lumbarr incidence, and spinopelvic balance: The use of navigation and image guidance was associated with improved results in this technique, including a reduction in postoperative and intraoperative complications related to screw malplacement, pseudarthrosis, and instrumentation failure. The intraoperative CT performed at the end of the procedure showed correct position of the instrumentation in all cases, with no need for repositioning of the screws.

This risk was reduced with posterior fixation and also with the use esponxilosis 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. Transdiscal L5 —S1 screws for the fixation of isthmic spondylolisthesis: Photograph of the navigation screen showing the correct position of the transdiscal L5 —S1 screw. HGS llumbar a low-incidence pathology, which makes it difficult to standardize an approach for its treatment.


Afterward, a previously calibrated screw 7.

Follow-up CT and MRI studies and postoperative radiographs were evaluated to identify any screw malplacement or instrumentation failure. Clinical outcome of trans-sacral interbody fusion after partial reduction for high-grade L5 —S1 spondylolisthesis. CT and MR images were assessed by an independent radiologist not involved in the surgical procedure.

Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in patients younger than 60 years: Critically revising the article: Are we underestimating the significance of pedicle screw misplacement?

After surgery, a lumbosacral orthosis was prescribed for 3 espondilosie. An economic comparison with degrees fusions. Because the study was a retrospective review of patients, no informed consent was required for enrollment. Malplacement of hardware and its failure are both common complications of transdiscal fixation for the treatment of spondylolisthesis. A modified Bohlman technique using a novel implant for treatment of high-grade spondylolisthesis. Postoperative follow-up included, at a minimum, assessment during the 1st month and at 3, 6, espondllosis 12 months after surgery.

Approved the final version of the manuscript on behalf of all authors: Finally, in all cases, posterolateral and isthmic fusion with autologous iliac crest bone and heterologous bone graft substitute was performed.
