Active clinical trials for "Spinal Stenosis"

describe the functional evolution of patients at more than 10 years post intervention. describe the evolution of pain, satisfaction, quality of life of patients to more than 5 years pot intervention.

The purpose of this retrospective data review is to evaluate the health economic drivers and complications of two surgical procedures: transsacral lumbar interbody fusion and transforaminal lumbar interbody fusion when used in conjunction with bilateral supplemental screw fixation as an adjunct to fusion. Devices used in both systems are cleared for use and comply with US regulations and requirements.

Prospective, multicenter non comparative and observational study (post-market clinical follow-up). Patients operated with PASS OCT® manufactured by MEDICREA® INTERNATIONAL between July 2016 and July 2017. The inclusion period will be 12 months and the follow-up 24 months

In a multinational prospective study, preoperative, intraoperative, perioperative and follow-up data on patients receiving thoracolumbar pedicle screw placement for degenerative disease or infections or tumors will be collected. The three arms consist of robot-guided (RG), navigated (NV), or freehand (FH) screw insertion.

Percutaneous epidural neuroplasty (PEN) is an effective interventional treatment for radicular pain. But in some cases with wire catheter like Racz catheter, contrast runoffs were not shown to the foramen. This study will show that contrast runoff will affect the results of PEN and in cases which contrast runoff are not shown, additional transforaminal epidural blocks will affect the results of PEN by reviewing medical record, retrospectively.

To measure ligamentum flavum thickness in patients with different nationalities, sexes, heights, ages, and weights from Xinjiang Uygur Autonomous Region of China with CT, explore the correlation between various factors and ligamentum flavum thickness, provide reference for pedicle screw placement and lumbar decompression surgery, develop individualized surgical programs, and can effectively reduce the incidence of unnecessary postoperative complications induced by misplacement.

The study is a prospective outcome study to evaluate the effectiveness and treatment outcomes of microendoscopic decompressive laminotomy (MEDL) with objective evaluation tools. The patients who fulfill the selection criteria will be enrolled to collect the pre-operative clinical data including demographic data, image studies, and functional evaluation for neurological symptoms and disability. The patient will receive MEDL and post-operative follow-up will be arranged at 1 week, 1 month, 6 months, and 12 months after the operation. All the collected data will be analyzed to evaluate the efficacy and treatment results of MEDL.

To investigate whether destroying the adjacent posterior ligamentous complex (PLC) has an effect on adjacent segment degeneration (ASD) after L5/S1 posterior lumbar interbody fusion (PLIF)

The study is being conducted to evaluate look the TOPS System when used in patients with degenerative spondylolisthesis and lumbar spinal stenosis who would normally be candidates for spinal fusion.

High percentage of chronic back pain is due to spinal stenosis. The clinical picture is of 'neurogenic claudication' which effects postural balance and stability. If conservative treatment fail to improve symptoms, an invasive treatment which includes spinal decompression can be done. The research is an observational prospective one, pre and post operational intervention. The aim is to examine whether an operational intervention improves quality of life, pain, postural balance an stability among patients. It's important to clarify, that although there is operational intervention, the research is observational. The decision weather to operate or not, is not a part of the research. The investigators assume that since there is a population that independently going through an operation, the investigators can observe this population and evaluate different aspects of the operation outcomes.
