Degeneration of the intervertebral discs is a progressive cascade of cellular, compositional and structural changes that is frequently associated with low back pain. As the first signs of disc degeneration typically arise in the disc's central nucleus pulposus (NP), augmentation of the NP via hydrogel injection represents a promising strategy to treat early to mid-stage degeneration. The purpose of this study was to establish the translational feasibility of a triple interpenetrating network hydrogel composed of dextran, chitosan, and teleostean (DCT) for augmentation of the degenerative NP in a preclinical goat model...

OBJECTIVES: In up to half of the cases, low back pain (LBP) is thought to be related to a degeneration of the lumbar disc. Lumbar total disc replacement (LTDR) emerged as an alternative to fusion, but its use and indications are still subject to debate. The purpose of this paper was to compare Health-related Quality of life (HRQOL) in patients undergoing LTDR for one or two-level degenerative disc disease (DDD) with the paired age and gender general population values and to assess functional disability and residual pain at one year after the surgical procedure...

STUDY DESIGN: A study of mechanically-induced herniation in punctured ovine discs followed by structural analysis. OBJECTIVE: To investigate whether an annular puncture influences the path that herniation takes by providing direct passage for nucleus through the annulus and therefore whether it increases the risk of acute herniation from overload at the site of damage independent of any longer-term degeneration. SUMMARY OF BACKGROUND DATA: 10 years after treatment with discography both degenerative changes and frequency of herniation have been shown to increase compared to untreated discs...

INTRODUCTION: Pain drawings have been frequently used in the preoperative evaluation of spine patients. For lumbar conditions comprehensive research has established both the reliability and predictive value, but for the cervical spine most of this knowledge is lacking. The aims of this study were to validate pain drawings for the cervical spine, and to investigate the predictive value for treatment outcome of four different evaluation methods. METHODS: We carried out a post hoc analysis of a randomized controlled trial, comparing cervical disc replacement to fusion for radiculopathy related to degenerative disc disease...

Accumulating evidence indicates that microRNAs can regulate the apoptosis of various cells. Apoptosis of nucleus pulposus cells plays an important role in the progression of intervertebral disc degeneration. The aim of this study is to investigate whether microRNA-143 (miRNA-143) is involved in the progression of intervertebral disc degeneration. In this study, the expression of miRNA-143 and its biological modulatory effects were examined. Messenger RNA and protein expression of miRNA-143 and B-cell lymphoma-2 (BCL2) in both normal and degenerative disc tissues was determined by using RT-PCR and western-blot assays...

BACKGROUND CONTEXT: The facet tropism is defined as the angular difference between the left and right facet orientation. The facet tropism was suggested to be associated with the disc degeneration and facet degeneration in the lumbar spine. However, little is known about the relationship between the facet tropism and pathological changes in the cervical spine and the mechanism behind. PURPOSE: This study was conducted to investigate the biomechanical impact of the facet tropism on the intervertebral disc and facet joints...

BACKGROUND: Cervical radiculopathy is the common clinical entity, often caused by "wear and tear" changes that occur in the spine. In the younger population, cervical radiculopathy is a result of a disc herniation or an acute injury causing foraminal impingement of an exiting nerve, whereas in the older individuals, it is due to foraminal narrowing from osteophyte formation, decreased disc height, and degenerative changes of the uncovertebral joints anteriorly and of the facet joints posteriorly...

There is a growing body of evidence concerning the significant role of silicon in development and composition of both connective and bone tissue. Bio-essential silicon shows strong chemical and biological affinity to aluminum, which is toxic and biologically inessential element. The presence of silicon was confirmed in a variety of tissues; however, it has never been examined in intervertebral disc tissue, neither in healthy nor in degenerated one. In this paper, for the first time in the literature, we present the content of silicon in the degenerated intervertebral disc tissue...

PURPOSE: Previous studies have demonstrated that total cervical disc replacement (cTDR) represents a viable treatment alternative to the 'gold standard' anterior cervical discectomy and fusion for the treatment of well-defined cervical pathologies at short- and mid-term follow-up (FU). However, the implementation and acceptance of a non-fusion philosophy is closely associated with its avoidance of adjacent segment degeneration. Proof of the functional sustainability and clinical improvement of symptoms at long-term FU is still pending...

BACKGROUND: Cervical stand-alone interbody cages have seen increasingly wider use over the plate-and-screw construct in single-level anterior cervical discectomy and fusion (ACDF) in the treatment of cervical disc herniation and degenerative spondylotic conditions. Despite positive clinical outcomes, the efficacy and safety of using these devices in contiguous multi-level ACDF, however, has remained controversial. CASE DESCRIPTION: This report discusses a burst fracture seen as a complication in multi-level cervical stand-alone cage use...

Back pain is a major contributor to disability and has significant socioeconomic impacts worldwide. The degenerative intervertebral disc (IVD) has been hypothesized to contribute to back pain, but a better understanding of the interactions between the degenerative IVD and nociceptive neurons innervating the disc and treatment strategies that directly target these interactions is needed to improve our understanding and treatment of back pain. We investigated degenerative IVD-induced changes to dorsal root ganglion (DRG) neuron activity and utilized CRISPR epigenome editing as a neuromodulation strategy...

INTRODUCTION: Lumbar interbody fusions have been widely used to treat degenerative lumbar disease that fails to respond to conservative treatment. This procedure is divided according to its approach: anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF), transforaminal lumbar interbody fusion (TLIF) and lateral lumbar interbody fusion (LLIF). Each approach has its own theoretical advantages and disadvantages; however, there have been no studies that compared these...
