Lumbar disc degeneration is one of the leading causes of chronic low back pain. The degenerative cascade is often initiated by an imbalance between catabolic and anabolic processes in the intervertebral discs. As a consequence of extracellular matrix degradation, neoinnervation and neovascularization take place. ⋯ Because of the high prevalence of long-term discogenic pain, regenerative biological therapies, including gene therapies, growth factors, cellular-based injections, and tissue-engineered constructs, have attracted significant attention in light of their potential to directly address the degenerative process. Understanding the pathophysiology of degenerative disc disease is important in both refining existing technologies and developing innovative techniques to reverse the degenerative processes in the discs. In this review, we aimed to cover the underlying pathophysiology of degenerative disc disease as well as its associated risk factors and give a comprehensive summary about the developmental, structural, radiological, and biomechanical properties of human intervertebral discs.

Review Meta Analysis
Coccygectomy for refractory coccygodynia: a systematic review and meta-analysis.
We sought to systematically assess and summarize the available literature on outcomes following coccygectomy for refractory coccygodynia. ⋯ Coccygectomy represents a viable treatment option in patients with refractory coccygodynia.

Randomized Controlled Trial Multicenter Study
Safety and Efficacy of Platelet Rich Plasma for Treatment of Lumbar Discogenic Pain: A Prospective, Multicenter, Randomized, Double-blind Study.
Interventions for chronic discogenic spine pain are currently insufficient in lowering individual patient suffering and global disease burden. A 2016 study of platelet rich plasma (PRP) for chronic discogenic pain previously demonstrated clinically significant response among active group patients compared with controls. ⋯ These findings are markedly different than the highly promising results of the 2016 PRP study. This study posits necessary caution for researchers who wish to administer PRP for therapeutic benefit and may ultimately point to necessary redirection of interventional research for discogenic pain populations.

Review Meta Analysis
The flexion relaxation phenomenon in nonspecific chronic low back pain: prevalence, reproducibility and flexion-extension ratios. A systematic review and meta-analysis.
The flexion relaxation phenomenon (FRP) is characterized by the reduction of paraspinal muscle activity at maximum trunk flexion. The FRP is reported to be altered (persistence of spinal muscle activity) in nonspecific chronic low back pain (NSCLBP) and is considered a promising biomarker. The aim of this systematic review was to synthetize current knowledge on FRP in the NSCLBP population regarding prevalence, the reliability of FRP measurement using surface electromyography (sEMG), the average value, and variation of the relaxation ratios (RR). ⋯ An altered FRP is frequently found in NSCLBP population using sEMG and the test has a good reproducibility. The difference between asymptomatic and NSCLBP FRR was significant. Nevertheless, considering the high heterogeneity observed, additional research is required to confirm the value of RR.

Review Meta Analysis
Non-operative treatment for low back pain: A review of evidence and recommendations.
Background Low back pain (LBP) is a healthcare problem with high global prevalence, with non-operative management being the first line of treatment in the majority of patients. This literature review summarizes the current evidence for various modalities of non-operative treatment for LBP. Methods We did a literature search to elicit high-quality evidence for non-operative treatment modalities for LBP, including Cochrane Database reviews and systematic reviews or meta-analysis of randomized controlled trials. ⋯ Conclusion The current evidence for non-operative treatment modalities for LBP is insufficient to draw conclusions or make recommendations to clinicians. High-quality trials are required before widespread use of any treatment modality. Considering that non-operative treatment is usually the first line of therapy for most patients with LBP, it deserves to be the focus of future research in spinal disorders.
