Before lumbosacral decompression surgery for radicular pain, selective nerve root block(SNRB) is a common procedure to identify the responsible compressed nerve root(RCNR) and predict surgical outcomes. However, the diagnostic accuracy of conventional SNRB is unsatisfactory, especially in terms of specificity. The main limitation is the uncontrolled distribution of anesthetics during injection: when anesthetics spread to surrounding soft tissues instead of acting directly on the RCNR, false-negative results may occur with persistent radicular pain; when anesthetics diffuse to two or more nerve roots including the RCNR, false-positive results may occur even if a normal nerve root is punctured, leading to misdiagnosis. This study aims to evaluate the diagnostic accuracy of a novel three-dimensional computed tomography multiplanar volume reconstruction (3D-CT MPVR) guided selective intraperineural nerve root block(SINRB) for identifying the RCNR in patients with lumbosacral radicular pain. The investigators hypothesize that this technique will achieve higher diagnostic specificity and overall accuracy than conventional SNRB, by ensuring anesthetics are delivered directly to the target nerve root. This improvement will help clinicians make more accurate surgical plans, achieve better targeted decompression, and ultimately improve postoperative pain relief and functional recovery for patients. The main research questions to be addressed in this study are: * What is the procedural success rate of SINRB? * Whether SINRB may cause clinically detectable nerve injury? * Whether sciatica is relieved after SINRB when only the responsible compressed nerve root is blocked? * Whether sciatica is relieved after SINRB when only a normal unaffected nerve root is blocked? Participants will: * Undergo one or two SINRB procedures and a single-level lumbar decompression surgery * Get assessment of pain, mobility disorder and neurological function
NCT02814825
The purpose of this post-market study is to collect data on ViviGen and how its use affects fusion rates in the cervical spine when used as additional grafting material to fill the cervical spacer. The patient population of interest is patients who have already elected to undergo a 2-3 level ACDF surgical procedure using ViviGen, per standard of care.
NCT07036445
The treatment of persistent lumbar radicular pain (LRP) using CT-guided epidural steroid injection (ESI) is widely used and associated with rare but serious complications. Platelet-rich plasma (PRP), which has recently been shown to promote healing and the anti-inflammatory process by delivering growth factors and cytokines, could be an alternative and potentially safer option. A previous study showed that PRP was as effective as ESI in treating this condition, without major complications. This study aims to compare these two treatments over the long term (2 years).
NCT00300898
The purpose of this study is to learn which of three minimally invasive procedures is the most effective for treatment of contained lumbar disc herniation.
NCT02300909
Prospective evaluation of the safety and efficacy of dHACM on clinical outcomes in lumbar laminectomy and microdiscectomy patients as assessed by Oswestry Disability Index.
NCT03303300
The five-repetition sit-to-stand test (5R-STS) has been used in many medical disciplines, but has never been correlated with or validated in regard to degenerative spinal diseases. The investigators aim to assess the possibility of using the standardized 5R-STS as an objective measure of functional impairment and pain severity in patients with degenerative lumbar spinal diseases.
NCT00974623
A multi-center, prospective, observational patient registry to collect information on the clinical outcomes and "real world" use of approved and commercially available bone graft substitutes, autograft and allograft.
NCT00000410
This study tests the effectiveness of different treatments for the three most commonly diagnosed lumbar (lower) spine conditions. The purpose of the study is to learn which of two commonly prescribed treatments (surgery and non-surgical therapy) works better for specific types of low back pain. In this part of the study, people with lumbar intervertebral disc herniation (damage to the tissue between the bones of the lower spine, or backbone) will receive either discectomy (surgical removal of herniated disc material) or non-surgical treatment. This study does not cover the cost of treatment.
NCT00908375
The purpose of this study is to evaluate whether pregabalin is effective in reducing the pain in patients who present with radicular pain due to a herniated disc, spinal stenosis or failed back surgery syndrome.
NCT01014520
The hypothesis of this study is that Gabapentin or Amitriptyline has no role in preemptive analgesia to reduce postoperative pain after lumbar diskectomies.
NCT00405041
The objective of the study is to evaluate the efficacy of a neuroprotective dietary supplement in patients suffering from herniated lumbar disc causing nerve root compression.
NCT00124774
This is a prospective randomised double blind comparison trial. Fifty patients will be included, 25 in the nucleoplasty treatment group, 25 in the control group. The nucleoplasty group will undergo the nucleoplasty treatment. Control group will undergo a sham treatment. Both groups will undergo a standardised post-operative care program. The study hypothesis is that nucleoplasty will lead to earlier pain reduction as compared with the sham treatment.
