Active clinical trials for "Spinal Stenosis"

The aim of this study was to investigate the emergence quality of patients extubated on prone or supine position after lumbar spinal surgery. 60 patients with ASA I-II who underwent lumbar spinal surgery between 18-65 years of age were included in the study. Patients with difficult intubation, BMI> 35kg / m2, asthma and reactive airway problems, cardiovascular disease and obstructive sleep apnea will not be included in the study. Initial data will be recorded after standard monitorization. Induction is made by 2 mg / kg propofol, 1 mg / kg fentanyl and 0.5 mg / kg rocuronium will be added for muscle relaxation. Patients with adequate muscle relaxation will be intubated with appropriate endotracheal tube and mechanical ventilation will be initiated. Patients who are then given prone positions on the operating table will be supported with side gels. The head will be placed in the face gel in a neutral position. For intraoperative analgesia, remifentanil infusion at 0.2mcg / kg / min will be applied. After laminectomy is completed and control of bleeding, 1 mg / kg Tramalol and 2 mg / kg Metaclopromide will be applied to all patients. At the end of the skin stitching, the inhalation agent will be closed and the fresh gas will be turned 6 lt 100% O2. Patients who want to be extubated in the prone position are left in this position while the other patients will be placed on the stretcher in a supine position for a short time. Patients will be decurarized be neostigmin with atropine. Extubation will be performed in both positions when spontanous ventilation begins at a tidal volume of 6ml / kg and a frequency of 12-20 / min. All the measures will be taken to ensure airway safety while the patient is extubated pron. The stretcher will be brought to the side of the operating table, investigator will be ready for reintubation and all the necessary persons will be with the patient. Aspiration frequency will be recorded for each patient. During recovery after extubation, the severity of cough will be evaluated as mild (only once), less (more than one but not continuous) and severe (continuously for 5 seconds). Aldrate scores of patient will be recorded and first 9-10 time is estimated from extubation time. Vomiting, nausea, respiratory insufficiency, inability to control the airway and obvious desaturation if seen are also recorded.

Different procedure of percutaneous endoscopic lumbar discectomy (PELD) was with ventral decompression of dural sac on the lumbar spinal stenosis remains unkonwn.The traditional transforaminal endoscopic spine system (TESSYS) of PELD has been used in clnical for many years, but cannot achieve dorsal decompression. A newly developed modified TESSYS procedure, "U" route PELD combining ventral and dorsal decompression was introduced. Nevertheless, the superior between TESSYS and "U" route PELD procedures on treating LSS remains unknown. This study is desinged to recruit degenerative lumbar spinal stenosis patients who underwent TESSYS or "U" rout PELD, recruited from January 2014 to December 2017. These patients will be followed up for 2 years, and assessed the minimum dura sac cross sectional area (mDCSA) by MRI, and visual analogue scale (VAS) and Oswestry Disability Index (ODI) at pre- and post-operation. The global clinical outcomes were evaluated using modified MacNab criteria postoperatively. Thus, comprehensively evaluate the safety and therapeutic effects of the two PELD procedures on LSS treatments.

This single-group cross-sectional cohort study will enroll approximately 25 patients at the North Texas VA Health Care System (VANTHCS) who have previously received off-label prescriptions of misoprostol for lumbar spinal stenosis for any duration and who are willing to provide verbal and informed consent. Patients will answer a questionnaire regarding pain and functional improvement especially in reference to misoprostol treatment. Patients will also be selected to have their walking tolerance (claudication distance) measured in an outpatient clinic setting to determine the severity of their lumbar spinal stenosis symptoms after having received misoprostol.

Introduction: This observational study is designed to test the equivalence between the clinical effectiveness of microdecompression and laminectomy in the surgical treatment of central lumbar spinal stenosis. Lumbar spinal stenosis is the most frequent indication for spinal surgery in the elderly, and as the oldest segment of the population continues to grow its prevalence is likely to increase. However, data on surgical outcomes are limited. Open or wide decompressive laminectomy, often combined with medial facetectomy and foraminotomy, was formerly the standard treatment. In recent years a growing tendency towards less invasive decompressive procedures has emerged. Many spine surgeons today perform microdecompression for central lumbar spinal stenosis. Prospectively registered treatment and outcome data are obtained from the Norwegian Registry for Spine Surgery (NORspine).

The intent of this study is to complete the collection of clinical data on subjects enrolled in the Stabilimax Dynamic Spine Stabilization IDE clinical trial (#G060214) sponsored by the now defunct Applied Spine Technologies Inc . The Applied Spine assets, including the clinical trial data, were acquired by Rachiotek, LLC in 2010. When Applied Spine ceased their funding of the trial, a number of enrolled patients had not yet completed the two year follow-up visit defined as the study endpoint in the clinical investigation plan. No additional patient treatment is required to complete the study. Rachiotek has interest in pursuing IDE approval for a new study and the information collected in this study is essential for supporting the new Investigational Device Exemption application.

The Long-Term Outcomes Study (LTOS) is a multi-center longitudinal cohort study of all patients who received the X-STOP device in the Pivotal Trial, Continued Access Protocol (CAP), or Cross-over Study (COS). It is designed to supplement postmarket safety and effectiveness data to be gathered in a Condition of Approval (CoA) study of a population of patients with moderately impaired physical function who elect to undergo X-STOP surgery.

This study is to evaluate the correlation between muscle atrophy (MA), sagittal alignment, and stenosis degree in patients with lumbar spinal Stenosis (LSS). From existing radiological images, specific radiographic parameters will be extracted. General Information (Age, sex, levels of stenosis, duration of symptoms) will be extracted from patient files.

Background : Segmental spinal instability after a laminectomy, and adjacent segment disease (ASD) at after an arthrodesis, are well-known concerns in spinal surgery, which may require re-interventions, usually by surgical arthrodesis, posing the problem of a new heavy intervention under general anesthesia, in often fragile patients. Trans-facet fixation (TFF) under local anesthesia and double fluoroscopic and CT guidance is a minimally invasive technique involving the placement of screws through the posterior facet joints, improving spinal stability. Purpose : The aim of our study is to evaluate the efficacy, in terms of pain reduction (VAS) and improvement of daily activities (ODI), of TFF under CT scan guidance in the context of low back pain and/or radiculalgia related to focal instability secondary to laminectomy or ASD. Methods : TFF were performed in 24 patients having a history of spinal surgery such as laminectomy and/or classic surgical arthrodesis and remaining symptomatic, at Nice University Hospital between 2017 and 2021 Pre- and postoperative pain and disability levels were measured using the visual analogue scale (VAS) and the Oswestry Disability Index (ODI), collected prospectively at systematic 6-month and 1-year follow-up visits. Long term evolution were assessed by phone consultation.

Spinal stenosis is a prevalent diagnosis, which is handled in a heterogeneous manner by clinicians. Moreover, when using steroidal epidural injections, successful treatment is currently defined as the satisfaction of the patient from the treatments, a subjective and non-quantifiable indicator. In this experiment, the investigators aim to evaluate thermographic images as an objective method for assessing the efficacy of steroidal epidural injections, the most common invasive treatment for pain associated with spinal stenosis

Purpose Physical activity reduces the risk of several diseases of the body and the mind1, 2 and can help the elderly maintain physical abilities and self-efficacy in daily life1. The overall purpose of the project is to provide clinicians with a tool to objectively assess physical activity in daily life and thus provide an informed basis for individualized care of elderly patients with spine disease. We would like to introduce this tool to a broad population of elderly patients with low back pain to give an overview of the range and variability in physical activity. We will also look into a method for accurate step count in spine disorders where patients have severe walking impairment due to affected lumbar nerve roots.
