Active clinical trials for "Spinal Stenosis"

Arthritis of the spine causes narrowing of the spinal canals and compression of the spinal nerves traveling into the legs, limiting walking ability. The vast majority of individuals with arthritis of the spine are not suited for surgery and most receive non-surgical treatment. However, we do not know what non-surgical treatments are effective in improving walking in these people. The purpose of our research is to test four new treatments for arthritis of the spine to see if they can improve walking ability. Each treatment approach focuses on the changes that occur in the spine and the whole person as a result of the arthritis that directly or indirectly impacts the ability to walk and perform usual daily activities. Because arthritis of the spine is a chronic condition usually does not go away, it is important that people acquire the knowledge, skills, and tools to manage their condition on their own. The treatments that investigators plan to test as part of this research proposal are aimed at achieving this goal. However, before the investigators can promote the use of these treatments they need to formally test them using strict scientific methods to make sure they do more good than harm. The four treatments include 1) a six week training program referred to as "Boot Camp for Stenosis" which provides one-on-one training on exercise and self-management strategies 2) a patient educational workbook and video on how to self-manage, 3) an electrical device that is placed on the lower back to reduce nerve pain when walking and 4) a spinal stenosis belt that people can wear to reduce pressure on the nerves while walking. The plan is to assess the change in walking distance using the various treatments and assess what impact the treatments have on peoples' overall function and quality of life. Innovative treatment approaches with a long term perspective are urgently needed to deal with the growing number of people with arthritis of the spine who are disabled. It is likely that there is not one solution to this problem - many people will require more than one type of treatment, but an important first step is to determine which treatments are effective, then tailor the treatments to the needs of each person.

In this prospective multi-centre double-blind trial the effect of the epiduroscopy will be examined in (approximately 300) adult patients with low back pain pain caused by failed back surgery syndrome (FBSS).

The purpose of this study is to determine whether NuCel is effective in promoting spinal fusion in degenerative disease of the lumbar spine.

The purpose of this study is to evaluate the safety and preliminary efficacy of NeoFuse in subjects with a diagnosis of degenerative disc disease (DDD) at 2 or more adjacent cervical vertebral levels between C3-C4 to C7-T1. All subjects in this study will undergo 2 or 3 level anterior cervical discectomy and fusion with anterior cervical plate fixation.

The primary purpose of the study is to measure the change in severity of symptoms and ability to function in every day activities in patients suffering from degenerative lumbar spinal stenosis after treatment with the Aperius® device.

The primary objective of the proposed pilot study is to determine the efficacy of pregabalin in prolonging the time to onset of pain and reducing the severity of pain associated with walking in patients with 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 pregabalin with respect to improvement in duration and distance of walking.

The goal of spinal fusion is to relieve pain and/or increase stability in painful or unstable spine joints. A patient may or may not receive rods and screws with the use of bone graft materials to facilitate bone growth and a fusion thus preventing movement of the bones of the spine. In this research study, bone graft substitute material called Bone Morphogenetic Protein-2 known as BMP-2 Infuse will be used. No hip bone will be used. The surgical procedure will consist of BMP-2 Infuse with or without the use of rods and screws.

Post-Approval Clinical Study Comparing the Long Term Safety and Effectiveness of coflex vs. Fusion to Treat Lumbar Spinal Stenosis

Individuals who undergo spine surgery often have a significant loss of blood and may require multiple blood transfusions. Research has shown that epsilon-aminocaproic acid (EACA) may reduce the amount of blood lost during surgery, which would decrease the number of blood transfusions required. This study will evaluate the safety and effectiveness of EACA at reducing blood loss and the need for blood transfusions in individuals undergoing spine surgery.

The purpose of this study is to determine if the ACADIA® Facet Replacement System is effective in the treatment of spinal stenosis. The primary objective of the study is to evaluate the overall success rate of the Anatomic Facet Replacement System in patients with spinal stenosis when compared to a posterior spinal fusion control.
