Описание
Sciatica and low back pain are common problems that lead to major costs in Western countries. The presence of herniated disc is generally considered as the leading cause of sciatica. However, recent findings indicate that the presence of this mechanism is not sufficient to explain all the clinical signs of radiculopathy and that inflammatory mechanisms contribute also to the pathophysiology of sciatica. Indeed, herniated discs contain large amounts of tumor necrosis factor (TNF-alpha) which can induce acute and chronic inflammation and pain. It has recently been demonstrated that TNF-alpha inhibitors (infliximab or etanercept) were able to prevent the occurrence of pain in an experimental model of sciatica. In addition, two independent preliminary studies have shown that patients treated with TNF-alpha inhibitors had better evolution than an historical control group. This study has been designed to verify the hypothesis that TNF-alpha has a major role in human sciatica and that anti-TNF-alpha agents are interesting therapeutic approaches in severe sciatica.

Medical evaluation requiring hospitalisation because of pain or functional handicap 4. Patients presenting a characteristic leg pain in the L3, L4, L5, or S1 territories plus at least one of the following: : - positive straight-leg-raising test with an elevation of less than 70° - positive femoral stretched - clear clinical sign of nerve root involvement - muscle strength deficiency or - sensory disturbances in clear cut dermatome or - lower limb reflex asymmetry. 5. Oswestry score greater than 50 6. If there is a past history of radicular pain involving the same nerve root, a 6 months interval free of leg pain is required. 7. A confirmed herniated disc on usual imaging techniques (CT scan or MRI) in the vicinity of the clinically involved nerve root that has been performed within the last 2 years. 8. Written informed consent Exclusion Criteria: 1. The presence of recent (<48 hours) severe muscle weakness (<3/5) or clinical signs of cauda equina compression, requiring immediate surgery. - If surgical procedure is required but is denied, either because of surgeon's decision or because of patient's fully informed decision, then this patient could be included in the protocol. 2. Comorbidities such as : - Coexisting infections (Chest X-ray will be performed to all patients and tuberculin skin test in case of doubt concerning a past history of tuberculous infection). - Autoimmune disease (other than RA). - History of cancer or malign lymphoproliferative disorders (unless the patient has been declared in remission for more than 5 years) - History of demyelinating disorders. 3. Pregnancy. 4. History of intolerance to adalimumab or any of its ingredients 5. Previous participation in this clinical study. 6. Participation in another clinical study within 4 weeks prior to the start of or during this study. 7.
