Espondilolistesis: técnicas quirúrgicas avanzadas – Unidad de Neurocirugia RGS

Follow-up CT and MRI studies and eapondilosis radiographs were evaluated to identify any screw malplacement or instrumentation failure. Transdiscal L5-S1 screws for the treatment of adult spondylolisthesis. Transdiscal screw versus pedicle screw fixation for high-grade L5-S1 isthmic spondylolisthesis in patients younger than 60 years: Our results presented here further demonstrate that screw malplacement and hardware breakage are greatly reduced with the use of online 3D image guidance compared tfatamiento the results from previous reports.

Intraoperative axial CT image showing correctly positioned transdiscal screws. Image guidance in transdiscal fixation for high-grade spondylolisthesis in adults with correct spinal balance.

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

More recently, the implementation of 3D image—guidance spine systems has improved the accuracy of instrumentation placement and decreased its morbidity.

Transdiscal L5 —S1 screws for the fixation of isthmic spondylolisthesis: 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.

In the upper levels, screws were also placed with image guidance in a standard fashion. Clin Orthop Relat Res Transsacral transdiscal L5 —S1 screws for the management of high-grade spondylolisthesis in an adolescent. In 5 cases, L4 —S1 instrumentation was placed, while in the other 3 cases, surgery consisted of transdiscal L5 —S1 fixation. After surgery, a lumbosacral orthosis was prescribed for 3 months.

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. Eur Spine J 21 Suppl 1: XVI Simposium internacional hernia discal cervical, dorsal y lumbar.

Lateral standing radiograph showing correct positioning of the instrumentation without signs of malplacement or trataiento. Reviewed submitted version of manuscript: Spine Phila Pa Pedicle screw insertion accuracy with different assisted methods: 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.

Six patients reduced their use of pain medication.

Photograph of the navigation screen showing screw placement along the correct trajectory. The mean duration of follow-up was 16 months range 9—24 monthsand no complication was observed during this period. Neurosurg Focus 44 1: METHODS The authors reviewed all traatamiento 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.

Grading of slippage was assessed according to the classification of Meyerding.

In their study, 25 patients age range 14 —60 years were treated with transdiscal fixation. Critically revising the article: Neurosurg Focus 20 3: The trxtamiento of reduction is to restore spinal anatomy, mainly recommended in patients with sagittal imbalance, and to lower the risk of pseudarthrosis.

This study is a retrospective review of HGS cases in which patients underwent surgery with transdiscal L5—S1 fixation between and at our institution.

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.

Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: Many approaches have been described, including anterior and posterior approaches, with or without interbody fusion; posterolateral fusion without decompression; Limbar vertebrectomy Gaines procedure ; and circumferential fusion and reduction.

There were no intraoperative or postoperative complications during the hospital stay, and as of the most recent follow-up, lumgar complications related to pseudarthrosis or hardware failure had been observed.
