Lumbar Spinal Fibrosis and TNF Alpha Inhibition
Post Operative Sciatica by Lumbar Spinal FibrosisTNF-alpha is the main cytokine implicated in the formation of lumbar spinal fibrosis. Inhibiting TNF-alpha could significantly decrease spinal fibrosis after lumbar discectomy.
Effect of Antidepressants on Back Pain
Back PainSciaticaThe purpose of this study is to determine whether different types of antidepressant medicines relieve back pain that has lasted at least six months on a daily basis. Study participants will be assigned to treatment with either a antidepressant acting on the serotonin system in the brain (fluoxetine), one acting on the noradrenaline system (desipramine, or to a control medication not expected to relieve pain (benztropine). Each participant will be seen at least nine times during their 12 weeks on medication. This is a phase 2/3, outpatient study.
Can Sciatica Patients Avoid Surgery?
Sciatic Nerve CompressionSciatica pain is associated with a disc disorder in 85% of cases. Sciatica is shown to resolve without treatments in the majority of cases. Spontaneous regression of the intervertebral disc herniation occurs where the herniation loses its volume partly or totally without surgical interventions. It has estimated that only 5 to 20% of patients with symptomatic intervertebral disc herniation require surgery. Most trials comparing surgical trials and conservative treatments of sciatica due to intervertebral disc herniation favor surgery, because it results in earlier relief of pain. However, one year after surgery, there were only a few differences in pain and disability between surgery and conservative treatment groups. It has shown that the number of surgeries (discectomies) decreased among patients with sciatica when treated by using a mechanical diagnosis and therapy approach (MDT) also called the McKenzie method. In addition, by using the MDT method it has also been shown that sciatica patient who were clinically classified as "centralizers" had good to excellent non-surgical outcomes and many of them avoided surgery, whereas non-centralizing pain has shown to predict worse treatment outcomes, chronic low back disorder and disability. Further, patients who do not have centralization will be 6 times more likely to undergo surgery.The primary aim of this multicenter randomized clinical trial is to find out how many patients with sciatica due to intervertebral disc herniation with radicular symptoms for at least 6 weeks, and who are on the waiting list for surgery, avoid surgery by treatment using the McKenzie method compared to advice to stay active. Secondary aims are to compare the patients' self-reported outcomes such as low back and leg pain intensity, disability, work ability, sick-leave days, fear avoidance beliefs, kinesiophobia, depression and quality of life. The outcomes are measured at baseline, two and three months in the non-surgical patients. In addition, in the patients who have surgery the outcomes are measured at baseline and the day before and one month after surgery. Follow-up measurements are at 12 and 24 months
Intradiscal Discogel® in Resistant Sciatica
Herniated DiscSciatica2 moreSciatica due to herniated disc is a major cause of disability in young adults. Surgery is the gold-standard and the only controlled treatment in case of failure of conservative treatment. Percutaneous chemonucleolysis with Discogel® may be a valuable alternative to surgery. In addition, Discogel® chemonucleolysis appears as a relatively innocuous technique which may avoid 2% complications after disc surgery and 5% repeated surgery (according to recent trials). This will be the first randomized trial comparing Discogel® chemonucleolysis versus surgery in patients with sciatica due to lumbar disc herniation and unresponsive to conservative medical treatments (including epidural steroid injections) Our expectation is that Discogel® chemonucleolysis will avoid surgery in 80% of the patients.
Ultrasound-guided Caudal or Interlaminar Corticosteroid Epidural Injection for Sciatica
SciaticaAn open-label randomized trial to compare the efficacy of ultrasound-guided caudal and interlaminar corticosteroid injections for the treatment of lumbar disk herniation-related sciatica.
[18F]FTC-146 PET/MRI in Healthy Volunteers and in CRPS and Sciatica
Complex Regional Pain SyndromeSciaticaChronic pain can result from injured or inflamed nerves, as occurs in people suffering from sciatica and CRPS. These nerve injuries or regions of nerve irritation are often the cause of pain in these conditions, but the current diagnostic tools are limited in pinpointing the area of origin. Several studies have implicated involvement of sigma-1 receptors in the generation and perpetuation of chronic pain conditions, others are investigating anti sigma-1 receptor drugs for the treatment of chronic pain. Using the sigma-1 receptor (S1R) detector and experimental radiotracer [18F]FTC-146 and positron emission tomography/magnetic resonance imaging (PET/MRI) scanner, the researchers may potentially identify the source of pain generation in patients suffering from complex regional pain syndrome (CRPS) and chronic sciatica. The ultimate goal is to assist in the optimization of pain treatment regimens using an [18F]FTC-146 PET/MRI scan. The study is not designed to induce any physiological/pharmacological effect.
Bilateral Sacroiliac Joint (SIJ) Injection in Lumbar Disc Prolapse
Lumbar Disc HerniationSciatica3 moreBilateral sacroiliac joint injection in symptomatic lumbar disc prolapse under ultrasound guidance and studying the effect of this technique on pain, spine mobility and activity of daily living.
High Versus Low Level of Lumbar Traction in Acute Lumbar Sciatica Due to Disc Herniation
Acute Lumbar Sciatica Secondary to Disc HerniationThe aim of this study is to compare two levels (high and low forces) of short term lumbar traction on pain and functional tests of the lower limbs in a specific population of patients presenting with acute lumbar sciatica secondary to disc herniation. The investigators hypothesize that, in this particular medical condition, high level of lumbar traction might be more effective than low level lumbar traction in decreasing the pain associated with acute sciatica.
Integrated Supported Biopsychosocial Self-Management for Back Related Leg Pain
Low Back PainSciatica4 moreGuidelines advocate several complementary modalities as alternatives to drugs and other invasive treatments for chronic low back pain (LBP) conditions. However, there is little high-quality research investigating treatments for back-related leg pain, one of the more severe and disabling presentations of LBP. The investigators are conducting a pilot study to assess the feasibility of a future phase II multi-site randomized clinical trial (RCT). The future trial will assess the comparative effectiveness of a novel supported biopsychosocial self-management (SBSM) intervention versus Medical Care (MC).
Effects of Control Scan for Presumed Difficult Epidural Infiltrations (ECHORACHIS)
SciaticaThe aim of this care protocol is to study the effects of scan to help epidural infiltration realization, in presumed difficult patients suffering from sciatica. These scans are already performed in our Rheumatology Department but our objective is to evaluate objectively its contribution for patients and doctors. Epidural infiltration in young patients, with an easy anatomical identification, causes generally no technical difficulties, therefore this protocol will only include patients presumed to have a difficult infiltration, that means those aged more than 60, and/or with BMI > 30 and/or suffering from scoliosis. This study concerns patients who are hospitalized in Rheumatology Department (Hospital of Nantes) for their first epidural infiltration for treatment-resistant lombosciatica. Patient will be randomized at Day 0, before infiltration. This latter will be performed in accordance to current practice. Tolerance data (pain and satisfaction) will be collected just after the infiltration and eventual complications will be reported within 48 hours after infiltration. Following treatment of lombosciatic will be realized through hospitalization, as usual. Scan is a safe, non invasive, painless and non radiating exam. It is the extension of the musculoskeletal clinical exam and it has already changed our rheumatology practices. The investigators hope at the end of this study, that results would confirm that scan can be a help in practice to perform epidural infiltrations.
