Acta Orthop Belg Eur Spine J 21 Suppl 1: Posterior reduction and monosegmental fusion with intraoperative three-dimensional navigation system in the treatment of high-grade developmental spondylolisthesis.

Eur Spine J 22 Suppl 6: Some patients also had lower-extremity symptoms attributable to radiculopathy. 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.

Complications described in published series of transdiscal pedicle screw fixation for HGS in adults.

Pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis. Image guidance in transdiscal fixation for high-grade spondylolisthesis in adults with correct spinal balance.

The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper. Also, none of the patients have returned to our pain unit because of tratamifnto pain, and all but 2 tratamiemto have reduced their intake of pain medication.

Treatment of spondylolysis and spondylolisthesis in children and adolescents. Six patients reduced their use of pain medication. Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in patients younger than 60 years: Transsacral transdiscal L5 —S1 screws for the management of high-grade spondylolisthesis in an adolescent. Axial CT images showing the proper lumabr of screws from the S-1 insertion point through the L-5 vertebral body.

Reduction of listhesis is one of the most controversial topics in HGS management. 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.

A modified Bohlman technique using a novel implant for treatment of high-grade spondylolisthesis. Standing radiographs were obtained in the event of complications and during the first follow-up visit, 1 month after surgery.

Malplacement of hardware and its failure are both common complications of transdiscal fixation for the treatment of spondylolisthesis.

Spine Phila Pa Prevalence of spondylolysis and its relationship with low back pain in selected population. After surgery, a lumbosacral orthosis was prescribed for 3 months. 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. Also, none of the patients required a transfusion after the procedure.

This technique has some advantages compared with other approaches, including the increased familiarity of the dspondilosis 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.

After calibration of the probe, tap, and screwdriver Fig. In their study, 25 patients age range 14 —60 years were treated with transdiscal fixation. CT and MR images were assessed by an independent radiologist not involved in the surgical procedure. Only cases involving patients older than 18 years with no upper limit were included in the study. 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 lumbarr in situ fusion and fixation procedures.

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

J Neurosurg Spine There were no intraoperative or postoperative complications during the hospital stay, and as of the most recent follow-up, no complications related to pseudarthrosis or hardware failure had been observed. Again, a espondilsois of studies on HGS with a substantial proportion of adult patients makes it difficult to generate a reliable standard recommendation. Summary of clinical and radiological data in 8 adult patients with HGS. This study is a retrospective review of HGS cases in which patients underwent surgery with transdiscal L5—S1 fixation between and at our institution.


Afterward, a previously calibrated screw 7.

HGS is a low-incidence pathology, which makes it difficult to standardize an approach for its treatment. Once the reference array was attached to the lower spinous process of the sacrum at S-2 or S-3, images were obtained with intraoperative 3D fluoroscopy Siemens Medical Solutions and 3D reconstruction was performed by the Brainlab system for spine navigation. 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.

Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: Are we underestimating the significance of pedicle screw misplacement? 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.

S —S, Neurosurg Focus 20 3: There was no significant difference between preoperative and postoperative spinopelvic parameters. Posterior transdiscal fixation was proposed in for HGS, and the use of spine navigation could make this technique more accessible and reduce the morbidity associated with the procedure.

One of the largest series, published by Collados-Maestre et al. Neurosurg Clin N Am However, there was a statistically significant improvement in the mean VAS score for low-back pain 6.
