In previously espondilozis studies, the incidence of reported complications related to transdiscal fixation for the treatment of HGS is generally quite low; with the exception of 1 study, in which the incidence was Once the instrumentation was finished, another fluoroscopic 3D scan is performed to check tratamiehto all screws were correctly tragamiento Fig.

Many approaches have been described, including anterior and posterior approaches, with or without interbody fusion; posterolateral fusion without decompression; L-5 vertebrectomy Gaines procedure ; and circumferential fusion and reduction.

In their study, 25 patients age range 14 —60 years were treated with transdiscal fixation. In addition, standing anteroposterior and lateral lumbosacral radiographs and lateral flexion-extension images, together with full spine standing lateral radiographs for spinal and pelvic alignment, were obtained in every case.

Eur Spine J 22 Suppl 6: Comparing the clinical and radiological outcomes of pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis versus unilateral transforaminal lumbar interbody fusion TLIF with posterior fixation using anterior cages. Many techniques have been described for HGS treatment, including anterior, posterior, and circumferential approaches.

Fusion was evaluated according to the Ray criteria 21 on CT images. The use of transdiscal pedicle screws with in situ fusion is a good option for treating HGS in patients with good sagittal balance.

J Neurosurg Spine 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. Their mean age was 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.

Again, a lack of studies on HGS with a substantial proportion of adult patients makes it difficult to generate a reliable standard recommendation. Because the sepondilosis was a retrospective review of patients, no informed consent was required for enrollment.

Moreover, new approaches and techniques are easier thanks to its application. A classic study by Roche and Rowe showed that the prevalence was about 4. Anterior transvertebral interbody cage with posterior transdiscal pedicle screw instrumentation for high-grade spondylolisthesis.

Neurosurg Focus 44 1: 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.

Neurosurg Clin N Am 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. Treatment of high-grade spondylolisthesis with Schanz recoil screws: A midline incision was made at the level of the spondylolisthesis, and subperiosteal dissection was performed until exposure of transverse process at every level to be treated.

Analysis and interpretation of data: Are we underestimating the significance of pedicle screw misplacement?

In our series, we did not perform a reduction, as there was no sagittal imbalance in any patient. 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.

To espondilosjs knowledge, the use of image guidance luumbar transdiscal screws has only been previously reported in the literature a single time—by Beringer et al.

Afterward, a previously calibrated screw 7. 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.
