17 Clinical Trials for Various Conditions
Low back pain (LBP) is both the single most common cause of disability and the leading cause of visits when military personnel go to their primary care doctors. Military personnel that deal with LBP can often be placed on limited duty profile. Not surprisingly, the direct and indirect costs of low back and neck pain accounts for approximately $88 billion of health care expenditure. In order to reduce the large financial and personal cost, clinical studies must be designed to treat LBP. This study will provide evidence-based medicine on a new regenerative medicine treatment option that may significantly affect military personnel with LBP. PRP (Platelet Rich Plasma) may offer alternate treatment methods that may help preserve the facet joint structures, and improve pain and function without causing destructive lesions or worsening degenerative joints. This healing process may favor improved participation with rehabilitation therapy and ultimately improve return to duty status. This study will also assess the effectiveness of point of care generated PRP, as a minimally invasive treatment option for treating lumbar facet pain. Specifically, PRP effectiveness will be compared to injecting placebo control when injected into facet joints.
This is a single-center, randomized, pilot study in adult subjects with facet mediated CLBP. Thirty (30) subjects are planned for initial enrollment and will be randomized 1:1 to receive ioveraº medial branch cryoneurolysis or radiofrequency ablation.
This study is being done to assess the safety of using the Angel Concentrated Platelet Rich Plasma System to process Platelet Rich Plasma (PRP) to treat arthritis of the low back (lumbar spondylosis).
Chronic pain incurs over half a trillion dollars in lost productivity (healthcare, lost wages, etc) annually. The most common source is low back pain (LBP), often from facet joints. The clinical evaluation of facet joints is challenging and anatomic imaging findings of facet joint; degenerative change; correlate poorly with pain. Therefore, it is difficult to select appropriate candidate patients/facet joints to treat. Misguided percutaneous treatment can cost thousands of dollars per session and delay diagnoses. Very limited retrospective information suggests that high grade peri-facet MRI signal change correlates to the side of LBP. However, this has not fully characterized the imaging findings and has not correlated to expert clinical exam/percutaneous response, precluding robust and meaningful clinical impact. Minimal retrospective data concludes inflammatory changes can be identified on FDG-PET exams, but the evidence of correlation to patient pain is lacking. Limited DWI exists for inflammatory spondyloarthropathies and myopathies, but is also lacking. This is an exploratory study investigating the utility of FDG PET activity and MRI signal change around facet joints in the clinical management of low back pain. This study will help determine if such imaging biomarkers could change clinical management. Additionally, this will provide data that will be vital to planning a larger prospective study evaluating the ability of imaging biomarkers to predict response to comparison medial branch blocks and RF ablation for treatment of facet joint pain.
Lumbar zygapophysial (facet) joint pain is a common cause of low back pain. Radiofrequency (RF) denervation is an effective and low risk treatment of chronic low back pain of suspected facet joint etiology. Blocks of the medial branches innervating the joints are commonly used to localize the pain and make the diagnosis of facet joint pain. There is currently no standard number of diagnostic blocks: zero, one, and two blocks have all been utilized. Considering the high false positive and false negative rates of these blocks, the cost: benefit ratio has been questioned. No study to date has examined the practice of diagnostic medial branch blocks before RF denervation. The purpose of this study is to determine the optimal number of blocks before radiofrequency denervation. Three groups of patients will be studied. In group I, patients will undergo RF denervation based on history and physical exam alone. In group II, patients will undergo RF denervation based on a positive response to a single diagnostic block with local anesthetic. In group III, patients will undergo RF treatment only after a positive screening block and a positive confirmatory block.
1. To demonstrate whether: i. Facet joint nerve blocks have therapeutic value beyond the duration of local anesthetic effect. ii. Adjuvant medications (Sarapin and Depo-steroids) provide additional relief of lumbar facet joint pain when used with facet joint nerve blocks. 2. To demonstrate whether or not there are clinically significant improvements in function of patients who receive lumbar facet joint nerve block with or without Sarapin and Depo-steroids (Group II) compared to patients randomized to Group I who receive only local anesthetic blocks. 3. To determine the adverse event profile in both groups.

The primary purpose of this protocol is to assess the ExAblate 2100 MR guided high intensity focused ultrasound device as an intervention for treatment of facetogenic lower back pain.
This single-site, single-arm study evaluates the feasibility, safety, tolerability, and efficacy of trans-arterial embolization (TAE) using Embozene microparticles for treating facetogenic pain due to facet arthropathy (osteoarthritis of the facet joints) in the lumbar spine.
Intradiscal delivery of bone marrow concentrate (BMC) into discs, facet, epidural space, and sacroiliac joints
Researchers are conducting this study to learn more about the side effects of bone marrow-derived stem cells when injected into the facet joints for the treatment of painful lumbar facet joint arthropathies.
Observational study of axial spine pain and hyperflexibility. Patients will receive physical exam maneuvers (traditional straight leg raise, FABER, facet loading as well as Beighton's hypermobility score) and blood / urine / saliva collection. They will also be separated into pain groups based on their response to injections. A correlation between exam findings and procedure group will be measured.
The purpose of this study is to document the effectiveness of the Nimbus Multi-tined Expandable Electrode (MEE) Probe in carrying out the heating and ablation (cutting) of the small medial branch nerves that carry pain information from the facet joints. Subjects will be selected, by way of clinical evaluation and response to medial branch blocks, to undergo this procedure of radiofrequency ablation/neurotomies of the medial branches to the specific painful facet joints of the low back in order to relieve pain. This will be carried out with an FDA-approved device using a standard technique that has been accepted throughout the world. The difference in this study is that we will make use of MRIs to image the lesion that is produced and a special EMG study to look at the muscles in the back to document the effectiveness of the device in creating the intended lesion. No other study of this kind has been produced to look at this or any other radiofrequency device in the treatment of low back pain.
Background: Facet interventions are the second most commonly performed procedure in pain clinics throughout the U.S, including in the military. Currently, there is no clear consensus regarding whether intra-articular (IA) blocks or medial branch blocks (facet joint nerve; MBB) are the best way to diagnose and treat facetogenic pain, or even whether or not to perform diagnostic/ prognostic blocks. Hypothesis: IA blocks will provide better relief than MBB, but MBB may better select patients for radiofrequency denervation. Purpose: Objective 1: Determine which "prognostic" block is the best predictor for RF denervation outcome; Objective 2: To determine whether adding steroids to IA or MBB may provide intermediate or long-term benefit to a subset of individuals. Research Design: Randomized, comparative-effectiveness study Methodology /Technical Approach: A total of 225 patients with non-radicular chronic low back pain (LBP) with suspected facetogenic etiology will be randomized in a 2:2:1 ratio to one of 3 groups: Group 1 will receive IA blocks with steroids and LA Group 2 will receive MBB with steroids and LA Group 3 will receive MBB with only saline Those individuals who obtain significant (≥ 50% in groups 1 and 2,3) but temporary (\< 1-month) relief will undergo radiofrequency (RF) denervation at their 1-month follow-up. In group 3, those patients who do not experience pain relief at 1-month will undergo RF denervation regardless of the pain relief they experience (as many practitioners in the military and civilian practices do without diagnostic blocks).1-3 Participants in Groups 1 and 2 who experience prolonged relief from their diagnostic/ therapeutic blocks with LA and steroids will not undergo RF denervation until their pain returns. Those individuals who experience prolonged relief lasting \> 6 months will be given the option of repeating the diagnostic/ therapeutic block. In Groups 1, 2 and 3 patients who experience prolonged relief from the diagnostic blocks, follow-up visits will be at 1-month, 3-months and 6-months after the block, or until their pain relief wears off. In those who undergo denervation based on a positive block, follow-ups will be performed 1, 3 and 6-months after the denervation provided they continue to experience significant (\> 50%) relief at each follow-up. Those individuals who fail to experience significant relief after denervation will be unblinded and exit the study per protocol.
A non-randomized, multi-site feasibility study to evaluate the safety of the Glyder Device in subjects with a history of lumbar facet joint disease (L2 to the sacrum) and successful neural ablation in which the facet joint is confirmed as the source of pain.
Investigate the potential of tissue grafting that includes human mesenchymal stem cells in the repair and potential stabilization of the degenerative Lumbar disk and facet joint denovo and at the time of surgical reconstruction. Our hypothesis proposes that stabilization will help restore normal structure and function in the degenerative lumbar spine may decrease chronic low back pain associated with the biomechanical demise of the degenerative disk or facet and may improve the natural history of adjacent segment disease found after spinal surgery.
