Active clinical trials for "Spinal Stenosis"

In this prospective multi-centre double-blind trial the effect of the X-ray examinations controlled periradicular therapy should be examined in (approximately 300) adult patients with low back pain pain caused by foraminal stenosis radiculopathy or spinal stenosis. A periradicular therapy (PRT) is a special radiological, low-risk therapy for chronic back pain caused by wear and tear of the cervical, thoracic, and lumbar spine or a herniated disc or disc bulge. Partially pain might also radiate to the hips or extremities and cause radicular symptoms.

The primary objective of the proposed pilot study is to determine the efficacy of oxymorphone hydrochloride and propoxyphene/acetaminophen combination in prolonging the time to onset of pain and reducing the severity of pain associated with walking in patients lumbar spinal stenosis that have clinical symptoms of neurogenic claudication. Neurogenic claudication is defined as movement induced leg pain, numbness, heaviness, or vague discomfort in part or all of one or both legs provoked with walking and standing and relieved by sitting, squatting, or forward flexion posturing. The secondary objective is to examine the functional benefit of oxymorphone hydrochloride and propoxyphene/acetaminophen combination with respect to improvement in duration and distance of walking.

The purpose of this study is to compare two surgery methods on lumbar spinal stenosis: minimal invasive decompression and X-stop. It is a prospective randomized multicenter study including patients with lumbar spinal stenosis on one or two levels, and neurogenic intermittent claudication. Effect assessment will include measures of pain and self-evaluated health condition, a full economical evaluation, and areal measurements (MR imaging and roentgen analyses)

This prospective, multicenter longitudinal five-year study of X-STOP PEEK usage in LSS patients is designed to supplement pre-market safety and effectiveness data with information on longer-term device performance in a population of patients with moderately impaired physical function at preoperative baseline (i.e., an "indicated" population) who elect to undergo X STOP PEEK surgery.

The purpose of this investigation is to evaluate the safety and effectiveness of the FLEXUS™ Interspinous Spacer as compared to the XSTOP® Spacer for the treatment of patients who are suffering from lumbar spinal stenosis at one or two contiguous levels.

Lumbar spinal fusion is commonly performed as a "last resort" in patients with chronic low back pain caused by degenerative changes and instability of the spine. The aim of this study is to compare two fusion devices, which are used in spinal surgery in order to promote the fusion of two lumbar vertebrae.

The primary objective is to use machine learning methods on large survey and health register data to identify participants with different treatment trajectories and health outcomes after surgical and/or conservative treatment for spinal disorders. Secondary objectives are to 1) conduct external validation of the prediction models, and 2) explore how the prediction models can be implemented into AI-based clinical co-decision tools and interventions.

Spine fusion is one of the most common procedures performed in spinal surgery. Several surgical techniques can achieve a solid union, but the intertransverse posterolateral fusion (PLF) is the most widely used. However, complications can develop when the bone graft material used is insufficient to achieve the desired fusion. With its unique properties, nanOss Bioactive can be mixed with bone marrow aspirate (BMA) and other graft materials to obtain new bone growth during the healing process. It is hypothesized that the use of nanOss Bioactive will result in fusion at 12 months, with CT evidence of bridging trabecular bone, less than 3mm of translational motion, and less than 5 degrees of angular motion. In addition, patients are expected to see an improvement in Oswestry Disability Index scores, VAS pain scores, and SF36 scores, while decreasing the use of pain medication, returning to work, and finding satisfaction in the results of their surgery.

The aim is to study if pre-surgery physiotherapy improves function, pain and health in patients with specific low back pain scheduled for surgery. Patients are followed over a two year period. A secondary aim is to study what factors predict short and long term outcomes.

The main objectives of the study are to evaluate the acceptance into operating flow, performance and safety of the AQrate Robotic Assisted System during the spinal fusion surgery
