Purpose The aim of this study was to evaluate the association between vertebral endplate morphology and the degree of lumbar intervertebral disc degeneration via magnetic resonance imaging (MRI). Methods In total, 150 patients who met the inclusion criteria and were 20–60 years of age were retrospectively evaluated. Patients were evaluated for the presence of intervertebral disc degeneration or herniation, and the degree of degeneration was assessed at all lumbar levels. Vertebral endplate morphology was evaluated based on the endplate sagittal diameter, endplate sagittal concave angle (ECA), and endplate sagittal concave depth (ECD) on sagittal MRI. The association between intervertebral disc degeneration or herniation and endplate morphological measurements was analysed. Results In MRI, superior endplates ( ie, inferior endplates of the superior vertebra) were concave and inferior endplates ( ie, superior endplates of the inferior vertebra) were flat at all disc levels. A decrease in ECD and an increase in ECA were detected at all lumbar levels as disc degeneration increased ( P < .05). At the L4-L5 and L5-S1 levels, a decrease in ECD and an increase in ECA were detected in the group with herniated lumbar discs ( P < .05). There was no association between lumbar disc degeneration or herniation and endplate sagittal diameter at lumbar intervertebral levels ( P > .05). At all levels, ECD of women was significantly lesser than that of men and ECA of women was significantly greater than that of men ( P < .05). Conclusions There is an association between vertebral endplate morphology and lumbar intervertebral disc degeneration. Vertebral endplates at the degenerated disc level become flat; the severity of this flattening is correlated with the degree of disc degeneration.

During the recent past focus has shifted from identifying intervertebral disc degeneration as being caused by physical exposure and strain to being linked with a variety of genetic variations. The objective of this review is to provide an up to date review of the existing research data regarding the relation of intervertebral disc degeneration to structural protein genes and their polymorphisms and thus help clearly establish further avenues where research into causation and treatment is needed. A comprehensive search using the keywords “Collagen”, “COL”, “Aggrecan”, “AGC”, “IVDD”, “intervertebral disc degeneration”, and “lumbar disc degeneration” from PubMed and Google Scholar, where literature in the English language was selected spanning from 1991 to 2019. There are many genes involved in the production of structural components of an intervertebral disc. The issues in production of these components involve the over-expression or under-expression of their genes, and single nucleotide polymorphisms and variable number of tandem repeats affecting their structures. These structural genes include primarily the collagen and the aggrecan genes. While genetic and environmental factors all come into play with a disease process like disc degeneration, the bulk of research now shows the significantly larger impact of hereditary over exposure. While further research is needed into some of the lesser studied genes linked to IVDD and also the racial variations in genetic makeup, the focus in the near future should be on establishment of genetic testing to identify individuals at greater risk of disease and deliberation regarding the use of gene therapy to prevent disc degeneration.

Objective. Angiopoietin-like protein 4 (ANGPTL4), encoding a glycosylated secreted protein, has been reported to be closely related to many kinds of diseases, including diabetes, tumor, and some musculoskeletal pathologies, such as rheumatoid arthritis, osteoarthritis, and osteoporosis. The aim of the current study is to investigate the role of ANGPTL4 in intervertebral disc degeneration and analyze the association of ANGPTL4 expression with Pfirrmann grades. Methods. A total of 162 nucleus pulposus tissues were collected from lumbar intervertebral disc herniation patients undergoing interforaminal endoscopic surgery. Real-time quantitative PCR and western blot were performed to determine the mRNA and protein expression of ANGPTL4 in nucleus pulposus samples. Statistical analysis was performed to analyze the association of ANGPTL4 expression with Pfirrmann grades. Results. Based on the clinical data of 162 patients, results showed that Pfirrmann grades were significantly associated with patients’ age ( r = 0.162 , P = 0.047 ) and were not significantly associated with patients’ gender ( P > 0.05 ). RT-qPCR and western blot results showed that the mRNA ( r = 0.287 , P < 0.05 ) and protein ( r = 0.356 , P < 0.05 ) expressions of ANGPTL4 were both closely associated with Pfirrmann grades. The expression of ANGPTL4 was remarkably increased in the groups of high IVDD Pfirrmann grades. Conclusion. The results demonstrated that ANGPTL4 expression was positively associated with the Pfirrmann grades and the severity of intervertebral disc degeneration. ANGPTL4 may be served as a candidate biomarker for intervertebral disc degeneration.

Abstract Background: Although adjacent segmental intervertebral disc degeneration (ASDD) is one of the most common complications after lumbar fusion, its exact mechanism remains unclear. As an antibody to RANKL, denosumab (Dmab) effectively reduces bone resorption and stimulates bone formation, which can increase bone mineral density (BMD) and improve osteoporosis. However, it has not been confirmed whether Dmab has a reversing or retarding effect on ASDD. Methods: Three-month-old female Sprague-Dawley rats that underwent L4–L5 posterolateral lumbar fusion (PLF) with spinous-process wire fixation four weeks after OVX surgery were given Dmab four weeks after PLF surgery (OVX+PLF+Dmab group). In addition, the following control groups were defined: Sham, OVX, PLF, and OVX+PLF (n=12 each).Then, manual palpation and X-ray were used to evaluate the state of lumbar fusion. The bone microstructure in the lumbar vertebra and endplate as well as the disc height index (DHI) of the L5/6 were evaluated by microcomputed tomography (μCT). The characteristic alterations of ASDD were identified via Safranin-O green staining staining. Osteoclasts were detected using tartrate-resistant acid phosphatase (TRAP) staining and the biomechanical properties of vertebra were evaluated. Aggrecan (Agg), metalloproteinase-13 (MMP-13), a disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) expression in the intervertebral disc were detected by immunohistochemistry and real-time polymerase chain reaction (RT-PCR) analysis.Results: Manual palpation showed clear evidence of the fused segment’s immobility. Compared to the OVX+PLF group, more new bone formation was observed by X-ray examination in the OVX+PLF+Dmab group. Dmab significantly alleviated ASDD by retaining disc height index (DHI), decreasing porosity of endplate, and increasing the biomechanical properties and BMD of vertebra. TRAP staining results showed a significantly decreased number after Dmab treatment, especially in subchondral bone and cartilaginous endplate. Moreover, the results of protein and mRNA expression in intervertebral disc (IVD) showed that Dmab not only inhibited matrix degradation by decreasing MMP-13 and ADAMTS-4 but also promoted matrix synthesis by increasing Agg. Conclusions: These results suggest that Dmab may be a novel therapeutic target for the treatment of ASDD.
