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. S —S, None of the patients had increased their analgesic dosage at the last follow-up.

Comparing the clinical and radiological outcomes of pedicular transvertebral screw fixation of espondololistesis lumbosacral spine in spondylolisthesis versus unilateral transforaminal lumbar interbody fusion TLIF with posterior fixation using anterior cages.

Reduction of listhesis is one of the most controversial topics in HGS management. 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 No reduction of the listhesis was performed in any case, as there was no spinal imbalance.

Espondilolistesis: técnicas quirúrgicas avanzadas

RESULTS Eight patients underwent posterior transdiscal esponsilolistesis instrumentation placement during this period, with a mean duration of follow-up of 16 months range 9 —24 months. Treatment of high-grade spondylolisthesis by posterior lumbosacral transfixation with transdiscal screws: Finally, in all cases, posterolateral and isthmic fusion with autologous iliac crest bone and heterologous bone graft substitute was performed.


Complications described in published series of transdiscal pedicle screw fixation for HGS in adults. In this technique, pedicle screws are inserted obliquely through the pedicle of S-1 in an anteromedial direction to espomdilolistesis sacral promontory. Espondilolistesix 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.

Lateral displacement is called lateral listhesis [3] or laterolisthesis. Transdiscal L5 —S1 screws for the fixation of isthmic spondylolisthesis: Some patients also had lower-extremity symptoms attributable to radiculopathy. Transsacral screw fixation for high-grade 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 etiology of spondylolisthesis.


Other symptoms may include tingling and numbness. High-grade spondylolisthesis HGShowever, is much less frequent, which makes it difficult to develop a general recommendation for its treatment. Spondylolisthesis is the displacement of one vertebra compared to another.

Not to be confused with SpondylosisSpondylitisSpondylolysisor Slipped disk. Critically revising the article: An economic comparison with degrees fusions.

A midline incision was made at lumbr level of the spondylolisthesis, and subperiosteal dissection was performed until exposure of transverse process at every level to be treated.

Fusion was evaluated according to the Ray criteria 21 on CT images. Intraoperative photograph of navigation-guided drilling for transdiscal screw placement.

Minimally invasive guidewireless, navigated pedicle screw placement: Also, none of the patients have returned to our pain unit because of back pain, and all but 2 patients have reduced their intake of pain medication. After surgery, a lumbosacral orthosis was prescribed for 3 months.


A slip or fracture of the intravertebral joint is usually acquired between the ages of 6 and 16 years, but remains unnoticed until adulthood. Essentials of Physical Medicine and Rehabilitation 3 ed. Blue arrow normal pars interarticularis. In patients with radiculopathy, a hemilaminectomy and foraminotomy of the affected root were performed. 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.

Spondylolisthesis – Wikipedia

HGS is a low-incidence pathology, which makes it difficult to standardize an approach for lumba treatment. We analyzed demographic and clinical parameters, including age, sex, symptoms, preoperative pain level, and daily activities.

Critically revising the article: Patients with symptomatic isthmic anterolisthesis are initially offered conservative treatment consisting of activity modification, pharmacological intervention, and a physical therapy consultation.

Spondylolisthesis is often defined in medical textbooks as displacement in any direction. Isthmic anterolisthesis is where there is a defect in the pars interarticularis. Annals of the Royal College of Surgeons of England.
