STUDY DESIGN: Cross-sectional study, nested in a prospective cohort (Cohort Hip and Knee, CHECK). OBJECTIVE: Low back pain (LBP) is very common and the main cause of activity limitations and work absence throughout the world. Although lumbar disc degeneration (LDD) is suggested as a cause of LBP, this association remains debatable. Therefore, this study assessed the association between the radiographic features of LDD and the presence of self-reported LBP, LBP persisting longer than three months, the perceived severity of LBP and presence of neuropathic pain...

Posterior branches of the lumbar spinal nerves are the anatomic substrate of pain in the lower back, sacrum and the gluteal area. Such pain may be associated with various pathologies which cause pain in the posterior branches of the lumbar spinal nerves due to entrapment, mechanical irritation or inflammatory reaction and/or degeneration. The posterior branches are of significant functional importance, which is related to the function of the structures they supply, including facet joints, which are the basic biomechanical units of the spine...

Segmental degeneration in the human lumbar spine affects both the intervertebral discs and facet joints. Facet joint degeneration not only affects the cartilage surface, but also alters the cellular properties of the cartilage tissue and the structure of the subchondral bone. The primary focus of this study is the investigation of these microstructural changes that are caused by facet joint degeneration. Microstructural analyses of degenerated facet joint samples, obtained from patients following operative lumbar interbody fusion, have not previously been extensively investigated...

BACKGROUND: Growth of nerve fibers has been shown to occur in a rabbit model of intravertebral disc degeneration (IVD) induced by needle puncture. As nerve growth may underlie the process of chronic pain in humans affected by disc degeneration, we sought to investigate the factors underlying nerve ingrowth in a minimally invasive annulotomy rabbit model of IVD by comparing the effects of empty disc defects with those of defects filled with poly(lactic-co-glycolic acid)/fibrin gel (PLGA) plugs...

Intradiscal O2-O3 injections are conventionally used as a minimally invasive treatment for lumbar disc herniation in patients not responding to conservative treatments. The aim of the present study is to report data of long-term imaging follow-up (3 years) of patients treated with intradiscal O2-O3 lumbar chemiodiscolysis. We evaluated the changes of disc volume and the modifications in disc appearance (in terms of disc degeneration) and endplate changes (according to Modic), comparing the results with a control group of patients...

BACKGROUND CONTEXT: Clinicians regard lumbar lordotic curvature (LLC) with respect to low back pain (LBP) in a contradictory fashion. The time-honored point of view is that LLC itself, or its increment causes LBP. On the other hand, recently, the biomechanical role of LLC has been emphasized and loss of lordosis is considered a possible cause of LBP. The relationship between LLC and LBP has immense clinical significance, since it serves as the basis of therapeutic exercises for treating and preventing LBP...

Multiple sclerosis (MS) is a demyelinating disorder characterized by massive neurodegeneration and profound axonal loss. Since myelin is enriched with sphingolipids and some of them display toxicity, biological function of sphingolipids in demyelination has been investigated in MS brain tissues. An elevation of sphingosine with a decrease in monoglycosylceramide and psychosine (myelin markers) was observed in MS white matter and plaque compared to normal brain tissue. This indicated that sphingosine toxicity might mediate oligodendrocyte degeneration...
