METHODS The authors reviewed all cases in which adult patients with correct spinal alignment were tratamiwnto for HGS with posterior transdiscal instrumentation placement guided with navigation between and at their institution. J Bone Joint Surg Am Intraoperative photographs showing the calibration of the awl-tap A and drill guide B. 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.

Axial CT images showing trtaamiento proper placement of screws from the S-1 insertion point through the L-5 vertebral body. Fernandez Ghelman 2 diciembre, Treatment of spondylolysis and spondylolisthesis in children and adolescents. The aim of reduction is to restore spinal anatomy, mainly recommended in patients with sagittal imbalance, and to lower the risk of pseudarthrosis.

However, lummbar 3 of the cases low-back pain was accompanied by radiculopathy to the feet. Transdiscal L5-S1 screws for the treatment of adult spondylolisthesis. The prevalence of this condition is not well defined. Preoperative and postoperative data were wspondilosis by means of the Wilcoxon signed-rank test.

Neurosurg Focus 44 1: 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.

Posterior reduction and monosegmental fusion with intraoperative three-dimensional navigation system in the treatment of high-grade developmental spondylolisthesis.

In espondiloiss study, 25 patients age range 14 —60 years were treated with transdiscal fixation. In our series, we did not perform a reduction, as there espondiloeis no sagittal imbalance in any patient.


Anterior transvertebral interbody cage with posterior transdiscal pedicle screw instrumentation for high-grade spondylolisthesis.

Pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis. This technique has some advantages compared with other approaches, including the increased familiarity of the surgical field for spine surgeons and the relatively low frequency of complications, which could be reduced using image-guidance systems, commonly used in most of the spine centers treating this kind of pathology.

Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: 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. Because the study was a retrospective review of patients, no informed consent was required for enrollment.

Chin Med J Engl These authors cited lukbar main advantages to this approach: Any other intraoperative or postoperative complications were also recorded. The most frequent intraoperative complication described is dural tear, accounting for Analysis and interpretation of data: The mean duration of follow-up was 16 months range 9—24 monthsand no complication was observed during this period.

Moreover, new approaches and techniques are easier thanks to its application. 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.

Operative management of adult high-grade lumbosacral spondylolisthesis.

The use of transdiscal pedicle screws with in situ fusion is a good option for treating HGS in patients with good sagittal balance. Summary of clinical and radiological data in 8 adult patients with HGS.

Also, none of the patients have returned to our pain unit because of back pain, and all but 2 patients have reduced their intake of pain medication. Photograph of the navigation screen showing screw placement along the correct trajectory. 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 ulmbar.


The Oswestry Disability Index ODI score was the primary outcome measure, with lower scores indicating less severe symptoms. As Collados-Maestre et al.

Subsequent studies of biomechanical properties of the transdiscal approach have demonstrated improvement in resistance against shear forces at the displaced level compared with posterolateral fusion, 4,8 stiffness 1. Some patients also had lower-extremity symptoms attributable to radiculopathy. 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.

Only cases involving patients older than 18 years with no upper limit were included in the study. Eur Spine J 22 Suppl 6: Are we underestimating the significance of pedicle screw misplacement? The authors did not find any case of pseudarthrosis in the patients treated with transdiscal fixation, despite the fact that pseudarthrosis is one of the most frequent complications associated with in situ fusion and fixation procedures.

The Oswestry disability index. High-grade spondylolisthesis HGShowever, is much less frequent, which makes it difficult to develop a general recommendation for its treatment.

Approved the final version of the manuscript on behalf of all authors: Intraoperative photograph of navigation-guided drilling for transdiscal screw placement. Treatment of high-grade spondylolisthesis with Schanz recoil screws: Again, a lack of studies on HGS with a substantial proportion of adult patients makes it difficult to generate a reliable standard espondjlosis.

RESULTS Eight patients underwent posterior transdiscal navigated instrumentation placement during this period, with a mean duration of follow-up of 16 months range 9 —24 months.
