Six patients were starting exercise and 2 had returned to their jobs. Posterior reduction esponeilolistesis monosegmental fusion with intraoperative three-dimensional navigation system in the treatment of high-grade developmental spondylolisthesis.

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 technique of transdiscal fixation has previously been described by Abdu et al. No reduction of the listhesis was performed in any case, as there was no spinal imbalance. Many approaches have been described, including espondilolistesie and posterior approaches, with or without interbody fusion; posterolateral fusion without decompression; L-5 vertebrectomy Gaines procedure ; and circumferential fusion and reduction.

Surgery was performed on a Jackson radiolucent surgical table with image guidance. Surgical treatment strategies for high-grade spondylolisthesis: Download Citation on ResearchGate Espondilolistesis degenerativa lumbar Las formas de espondilolistesis que se observan con mayor frecuencia en el. Finally, in all cases, posterolateral and isthmic fusion with autologous iliac crest bone and heterologous bone graft substitute was performed. The Journal of Bone and Joint Surgery.

J Neurosurg Spine Schmorl’s nodes Degenerative disc disease Spinal disc herniation Facet joint arthrosis. The intraoperative CT performed at the end of the esplndilolistesis showed correct position of the instrumentation in all cases, with no need for repositioning of the screws. Critically revising the article: In their study, 25 patients espoondilolistesis range 14 —60 years were treated with transdiscal fixation.

The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper. Once the instrumentation was finished, another fluoroscopic 3D scan is performed to check that all screws were correctly positioned Fig.

No reduction of the listhesis was performed in any case, as there was no spinal imbalance. Operative management of adult high-grade lumbosacral spondylolisthesis.

Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in lumbqr younger than 60 years: Intraoperative photograph showing the use of a navigated awl-tap for transdiscal screw placement.

The Oswestry index before surgery was 3. 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.

High-grade spondylolisthesis HGShowever, is much less frequent, which makes it difficult to develop a general recommendation for its treatment. Annals of the Royal College of Surgeons of England. Transdiscal L5-S1 screws espindilolistesis the treatment of adult spondylolisthesis.

X-ray of a grade 4 anterolisthesis at L5-S1 with spinal misalignment indicated. These authors cited 4 main advantages to this approach: Classification by degree of the slippage, as measured as percentage of the width of the vertebral body: The use of transdiscal pedicle screws with in situ fusion is a good option for treating HGS in patients with good sagittal balance. The Oswestry disability index. S —S, A slip or fracture of the intravertebral joint is usually acquired between the ages of 6 and 16 years, but remains unnoticed until adulthood.

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 of interbody implants and circumferential approaches. Subsequent studies of biomechanical properties of lumbra transdiscal approach have demonstrated improvement in resistance against shear forces at the displaced level compared with posterolateral fusion, 4,8 stiffness 1.

Treatment of spondylolysis and spondylolisthesis in children and adolescents. In patients with radiculopathy, a hemilaminectomy and foraminotomy of the affected root were performed.
