Recent studies found that the pathologic features of discs obtained from the patients with discogenic low back pain were the formation of the zones of vascularized granulation tissue, with extensive innervation in fissures extending from the outer part of the annulus into the nucleus pulposus. Studies suggested that the degeneration of the painful disc might originate from the injury and subsequent repair of annulus fibrosus. Growth factors such as basic fibroblast growth factor, transforming growth factor β1, and connective tissue growth factor, macrophages and mast cells might play a key role in the repair of the injured annulus fibrosus and subsequent disc degeneration. Although there exist controversies about the role of discography as a diagnostic test, provocation discography still is the only available means by which to identify a painful disc. A recent study has classified discogenic low back pain into two types that were annular disruption-induced low back pain and internal endplate disruption-induced low back pain, which have been fully supported by clinical and theoretical bases. Current treatment options for discogenic back pain range from medicinal anti-inflammation strategy to invasive procedures including spine fusion and recently spinal arthroplasty. However, these treatments are limited to relieving symptoms, with no attempt to restore the disc's structure. Recently, there has been a growing interest in developing strategies that aim to repair or regenerate the degenerated disc biologically.展开更多

Recent ...Chronic low back pain has a huge impact on daily living and a negative economic and professional effect. It is a matter of debate and concern for all health professionals involved, particularly spine surgeons. Recent discoveries on the innervation and biochemical properties of the intervertebral disc clarify the role of this structure as a possible cause of chronic low back pain. However, multiple causes may be present in the same patient making the diagnosis a challenging process. Discogenic pain is defined as a chronic low back pain induced by a degenerative disc disease. There are no specific characteristics of discogenic pain, although it has a higher incidence in younger age, it is usually localized medially in the back, worsens with axial loading and improves with recumbence. In the last decades we have assisted the emergence of multiple treatment techniques. However, neither the conservative treatment nor the interventional management has strong evidence in treating discogenic pain. Randomized control clinical trials are sought to improve patient outcome. Meanwhile, we believe each patient should be approached on an individual base. Discogenic pain: we care.展开更多

Inclusion criteria encompassed all facet joint interventions performed in a controlled fashion. The pain relief of greater than 50% was the outcome measure for diagnostic accuracy assessment of the controlled studies with ability to perform previously painful movements, whereas, for randomized controlled therapeutic efficacy studies, the primary outcome was significant pain relief and the secondary outcome was a positive change in functional status. For the inclusion of the diagnostic controlled studies, all studies must have utilized either placebo controlled facet joint blocks or comparative local anesthetic blocks. In assessing therapeutic interventions, short-term and long-term reliefs were defined as either up to 6 mo or greater than 6 mo of relief. The literature search was extensive utilizing various types of electronic search media including Pub Med from 1966 onwards, Cochrane library, National Guideline Clearinghouse, clinicaltrials.gov, along with other sources includingprevious systematic reviews, non-indexed journals, and abstracts until March 2015. Each manuscript included in the assessment was assessed for methodologic quality or risk of bias assessment utilizing the Quality Appraisal of Reliability Studies checklist for diagnostic interventions, and Cochrane review criteria and the Interventional Pain Management Techniques- Quality Appraisal of Reliability and Risk of Bias Assessment tool for therapeutic interventions. Evidence based on the review of the systematic assessment of controlled studies was graded utilizing a modified schema of qualitative evidence with best evidence synthesis, variable from level Ⅰ to level Ⅴ.RESULTS: Across all databases, 16 high quality diagnostic accuracy studies were identified. In addition, multiple studies assessed the influence of multiple factors on diagnostic validity. In contrast to diagnostic validity studies, therapeutic efficacy trials were limited to a total of 14 randomized controlled trials, assessing the efficacy of intraarticular injections, facet or zygapophysial joint nerve blocks, and radiofrequency neurotomy of the innervation of the facet joints. The evidence for the diagnostic validity of lumbar facet joint nerve blocks with at least 75% pain relief with ability to perform previously painful movements was level Ⅰ, based on a range of level Ⅰ to Ⅴ derived from a best evidence synthesis. For therapeutic interventions, the evidence was variable from level Ⅱ to Ⅲ, with level Ⅱ evidence for lumbar facet joint nerve blocks and radiofrequency neurotomy for long-term improvement(greater than 6 mo), and level Ⅲ evidence for lumbosacral zygapophysial joint injections for short-term improvement only.CONCLUSION: This review provides significant evidence for the diagnostic validity of facet joint nerve blocks, and moderate evidence for therapeutic radiofrequency neurotomy and therapeutic facet joint nerve blocks in managing chronic low back pain.展开更多

Using ＂evidence-based radiology＂ methods, the comparative roles of high intensity zone （HIZ） in diagnosing discogenic LBP were evaluated. Methods A focused clinical question was designed and a Pubmed and manual search were performed to identify the role of HIZ on MRI T2WI compared with discography. The studies retrieved were assessed for validity and strength. Sensitivity, specificity, likelihood ratios （LRs） and graphs of conditional probability were evaluated from the best current study by evidence-based radiology. Results Best evidence was retrieved in ten articles from 1992 to 2007. The best evidence level was lb and the strength of the evidence included： sensitivity 0.63 （0.51,0.76）, specificity 0.97 （0.92, 1.00）, positive predictive value 0.95, negative predictive value 0.72, positive LRs 18.37 and negative LRs 0.38. The gold standard of discogenic LBP is the provocative discography. Conclusions For suspected discogenic LBP, HIZ is limited for the diagnosis if HIZ is positive, which suggests further discography. In contrast HIZ is a good test for diagnosis if HIZ is negative, which indicates the disease can be excluded.展开更多

Methods： From September 2004 to November 2006, 172 patients underwent percutaneous nucleoplasty for chronic LBP in our department. Forty-one of these patients were followed up for a mean period of 67 months. Nucleoplasty was performed at L3/4 in 1 patient; L4/5 in 25 patients; L5/$1 in 2 patients; L3/4 and L4/5 in 2 patients; L4/5 and L5/$1 in 7 patients; and L3/4, L4/5, and L5/$1 in 4 patients. Patients were assessed preoperatively and at 1 week, 1 year, 3 years, and 5 years postoperatively. Pain was graded using a 10-cm Visual Analogue Scale （VAS） and the percentage reduction in pain score was calculated at each postoperative time point. The Oswestry Disability Index （ODI） was used to assess disability-related to lumbar spine degeneration, and patient satisfaction was assessed using the modified MacNab criteria. Results： There were significant differences among the preoperative, 1-week postoperative, and 3-year postoperative VAS and ODI scores, but not between the 3- and 5-year postoperative scores. There were no significant differences in age, sex, or preoperative symptoms between patients with effective and ineffective treatment, but there were significant differences in the number of levels treated, Pfirrmann grade of intervertebral disc degeneration, and provocative discography findings between these two groups. Excellent or good patient satisfaction was achieved in 87.9% of patients after 1 week, 72.4% after 1 year, 67.7% after 3 years, and 63.4% at the last follow-up. Conclusions： Although previously published short- and medium-term outcomes after percutaneous nucleoplasty appeared to be satisfactory, our long-term follow-up results show a significant decline in patient satisfaction over time. Percutaneous nucleoplasty is a safe and simple technique, with therapeutic effectiveness for the treatment of chronic LBP in selected patients. The technique is minimally invasive and can be used as part of a stepwise treatment plan for chronic LBP.展开更多
