Active clinical trials for "Spinal Stenosis"

Background: A significant portion of cardiac amyloidosis patients have a 5 to 10 years prior history of spinal canal stenosis, reflecting a diagnostic red flag that should raise suspicion for amyloidosis presence. Mild troponin release and NT-proBNP elevation, both serum cardiac biomarkers, often coincide with cardiac amyloidosis. Early cardiac amyloidosis treatment improves survival, warranting timely diagnosis. Study aim: to test a prospective screening strategy, based on serum cardiac biomarkers, to increase early detection of cardiac amyloidosis in patients with spinal canal stenosis. Design: Single-centre prospective observational non-interventional diagnostic study. Methods: Consecutive patients during a one-year period in AZ Sint-Jan Bruges, without known cardiac amyloidosis history and scheduled for spinal canal stenosis surgery, will have cardiac evaluation including serum cardiac biomarker (high-sensitive troponin T and NT-proBNP) assessment, electrocardiography and transthoracic echocardiography. During surgery, all patients will undergo ligamentum flavum biopsy to evaluate presence and burden of transthyretin amyloid deposition (Congo-red staining and immune histochemistry). All patients with suspicion for cardiac amyloidosis will undergo further diagnostic testing (including laboratory test and bone scintigraphy). A chronologic cascade screening process will be used starting with abnormal serum cardiac biomarkers (high-sensitive troponin T ≥ 14 ng/ml and/or NT-proBNP > 125 pg/ml), followed by electrocardiography, transthoracic echocardiography and finally ligamentum flavum biopsy results. The diagnostic performance of this biomarker-based strategy will be compared to electrocardiography, echocardiography and ligamentum flavum biopsy. Conclusion: It is hypothesised that serum cardiac biomarker testing in patients undergoing spinal canal stenosis surgery represents a simple and valuable prospective screening strategy for early detection of cardiac amyloid(osis).

Ethics committee approval was taken on October 22, 2019, numbered 19/342. 120 adult patients who will undergo spine stabilization surgery between October 2019 and January 2020 in "Gülhane Training and Research Hospital" were planned to be included in the study. Patients will be randomized to 30 patients with MTP block (Group MTP) and ESP block (Group ESP) and no block (Group K) in addition to patient-controlled analgesia (PCA). Postoperative pain scores, analgesic use, number of PCA button presses, total amount of opioid administered and complications due to opioids will be recorded. The obtained data will be compared statistically.

The purpose of this study was to quantify potential short- and long-term benefits of robotically-guided minimally invasive spine surgery in instrumentation of degenerative lumbar or lumbosacral spine disease in adult patients, in comparison to instrumentation in a matching cohort of control patients performed using conventional freehand technique.

This study was started from Oct. 2015. This study aimed to evaluate the outcome of bracing following transforaminal lumbar interbody fusion (TLIF) in patients with degenerative lumbar spine diseases.

Aging of the back is common in the older people and can result in difficulties standing and walking. Conservative treatment is recommended before considering surgery. Some recommended exercises involve the use of expensive equipment. The present study plans to evaluate if specifically moving the nerves in the legs/back and improving flexibility of the hip and back can benefit patients. These exercises require no equipment, are simple to perform, and can provide patients a way to continue to perform these exercises at home. The purposes of this study are to (1) observe the benefit of a treatment program involving moving the nerves of the leg/back, stretching the legs and low back in patients with low back pain and difficulties walking; and (2) determine if benefits received remain at a 3-month follow-up.

This is a single-center study evaluating the outcomes of patients with painful lumbar spinal stenosis who were treated with the mild procedure (minimally invasive lumbar decompression. The patients will be followed for 6 months after the procedure.

This is a multi-center, prospective, clinical study to assess the clinical application and outcomes of MILD® Interlaminar Decompression in patients with symptomatic lumbar spinal stenosis.

In actual practice the patients with mild or moderate lumbar spinal stenosis symptoms receive an epidural infiltration and participate in kyphosis reeducation in first intention. Yet the kyphosis reeducation did not show a real profit in the time compared with the natural evolution of the pathology. The study assume that the spinal mobility reeducation will reduce the incidence of pain recurrences compared with the classic kyphosis reeducation.

The most common forms of injection used for the treatment of degenerative lumbar spinal stenosis (DLSS) patients with neurogenic claudication (NC) are the caudal and inter-laminar epidural injections of anesthetic and steroid. Unilateral transforaminal epidural steroid injections (TESI) are also used to alleviate patients' symptoms of NC from DLSS, particularly in patients whose level of stenosis is L4-5 or higher. However, these unilateral injections do not cross the midline, so in cases of lower extremity pain and symptoms on both sides, a bilateral TESI would probably be more beneficial. To date, there have not been any well designed prospective studies to determine the effectiveness of bilateral TESI below the level of stenosis in DLSS patients with NC. Therefore, the goal of this prospective, non-randomized case-series outcome study is to evaluate the effectiveness of BTESI in alleviating symptoms of NC, as well as improving function in patients with DLSS. The hypothesis is that BTESI at the level below the most stenotic segment of the central canal of the lumbar spine decreases symptoms of NC and improves function in patients with DLSS.

The aim of the proposed study is to examine the effect of DEX on the inflammatory response in major surgery. More importantly, the investigators will correlate changes in the concentration of inflammatory mediators with meaningful clinical outcomes.
