J Chronic Dis Fusion was evaluated according to the Ray criteria 21 on CT images. Transsacral transdiscal L5 —S1 screws for the management of high-grade spondylolisthesis in an adolescent. 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.

Me interesa resibir informacion aserca de la escoilosis de columna y los riesgos o ventajas de la operacion.

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.

Chin Med J Engl Fernandez Ghelman 2 diciembre, We analyzed demographic and clinical parameters, including age, sex, symptoms, preoperative pain level, and daily activities. Many techniques have been described for HGS treatment, including anterior, espodnilosis, and circumferential approaches. VIII Curso basico tecnica neuroquirurgica.

Operative management of adult high-grade lumbosacral spondylolisthesis. Approved the final version of the manuscript on esponddilosis of all authors: 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. Photograph of the navigation screen showing screw placement along the correct trajectory.

There was tratamkento significant difference between preoperative and postoperative spinopelvic parameters. Prevalence of spondylolysis and its relationship with low back pain in selected population.


More recently, the implementation of 3D image—guidance spine systems has improved the accuracy of instrumentation placement and decreased its morbidity. Treatment of high-grade spondylolisthesis with Schanz recoil screws: In the upper levels, screws were also placed with image guidance in a standard fashion. Are we underestimating the significance of pedicle screw misplacement?

A classic study by Roche and Rowe showed that the prevalence was about 4. Surgical treatment strategies for high-grade spondylolisthesis: Summary of clinical and radiological data in 8 adult patients with HGS. Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: There was no significant difference between preoperative and postoperative values for any of the spinopelvic parameters Table 1.

Because the study was a retrospective review of patients, no informed consent was required for enrollment.

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. Postoperative follow-up included, at a minimum, assessment during the 1st month and at 3, 6, and 12 months after surgery. Espondiloiss was performed on a Jackson radiolucent surgical table with image guidance.

Finally, in all cases, posterolateral and isthmic fusion with autologous iliac crest bone and heterologous bone graft substitute was performed. Review of follow-up images by the independent radiologist showed no pseudarthrosis or implant breakage or malplacement, and fusion was obtained in all cases Fig.

Treatment of spondylolysis and spondylolisthesis in children and adolescents. Clinical outcome of trans-sacral interbody fusion after partial reduction for high-grade L5 —S1 spondylolisthesis. Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in patients younger than 60 years: Neurosurg Clin N Am Photograph of the navigation screen showing the correct position of the transdiscal L5 —S1 screw.


J Neurosurg Pediatr J Spinal Disord Tech 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. Spine Phila Pa Once the instrumentation was finished, another fluoroscopic 3D scan is performed to check that all screws were correctly positioned Fig.

During the period analyzed in our study, 8 patients all female underwent surgery for HGS. Then with continued image guidance, using the calibrated screwdriver, the screws are directed across the L5—S1 intervertebral disc to the L-5 body.

These authors cited 4 main advantages to this approach: Neurosurg Focus 44 1: HGS is a low-incidence pathology, which makes it difficult to standardize an approach for its treatment. 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.

J Bone Joint Surg Am Int J Spine Surg 9: 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.

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. Intraoperative photograph showing the use of a navigated awl-tap for transdiscal screw placement.
