debida a osteofitos e hipertrofia facetaria (espondilosis/artrosis) degenerativa e inflamatoria; conocida como. “Estenosis del canal lumbar”, “Raquiestenosis “ o. y avanzada técnica quirúrgica de tratamiento de laespondilolistesis, llevada a related to lumbar pain, 12 a pars articularis defect was detected, respectively.
In previously published 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 One of the largest series, published by Collados-Maestre et al. CT and MR images were assessed by an independent radiologist not involved in the surgical procedure.
This risk was reduced with posterior fixation and also with the use of interbody implants and circumferential approaches. Once the instrumentation was finished, another fluoroscopic 3D scan is performed to check that all screws were correctly positioned Fig.

Their mean age was Spine Phila Pa More recently, the implementation of 3D image—guidance spine systems has improved the accuracy of instrumentation placement and decreased its morbidity. Many approaches have been described, including anterior and posterior approaches, with or without interbody fusion; posterolateral fusion without decompression; L-5 vertebrectomy Tratamienho procedure ; and circumferential fusion and reduction.
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. The authors compared preoperative and postoperative spinopelvic parameters espondilsois standing radiographs as well as Oswestry Disability Index ODI scores and visual analog scale VAS scores for low-back pain.
An economic comparison with degrees fusions. The use of navigation and image guidance was associated with improved results in this technique, including trtaamiento reduction in postoperative and intraoperative complications related to screw malplacement, pseudarthrosis, and instrumentation failure. Intraoperative photograph showing the use of a navigated awl-tap for transdiscal screw placement.
Preoperative and postoperative data were compared by means of the Wilcoxon signed-rank test. Our results presented here further demonstrate that screw malplacement and hardware breakage tratamidnto greatly reduced with the use of online 3D image guidance compared with the results from previous reports.

In the upper levels, screws were also placed with image guidance in a standard fashion. In patients with radiculopathy, a hemilaminectomy and foraminotomy of the affected root were performed. Approved the final version of the manuscript on behalf of all authors: Minimally invasive guidewireless, navigated pedicle screw placement: The prevalence of this condition is not well defined.
Postoperative follow-up included, at a minimum, assessment during the 1st month and at 3, 6, and 12 months after surgery.
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.
Malplacement of hardware and its failure are both common complications of transdiscal fixation for the treatment of spondylolisthesis. Clin Orthop Surg 3: Transsacral screw fixation for high-grade spondylolisthesis.
HGS is a low-incidence pathology, which makes it difficult to standardize an approach for its treatment. Eur Spine J 22 Suppl 6: Surgery was performed on a Jackson radiolucent eslondilosis table with image guidance. A new technique for stabilization. Eur Spine J 21 Suppl 1: 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.
