CONTEXT AND OBJECTIVE There is controversy regarding which imaging method is best for identifying early degenerative alterations in intervertebral discs. No correlations between such methods and histological finds are presented in the literature. The aim of this study was to correlate the thickness of intervertebral discs measured on simple radiographs with the degree of degeneration seen on ma...

In this study, we used microarray analysis to investigate the biogenesis and progression of intervertebral disc degeneration. The gene expression profiles of 37 disc tissue samples obtained from patients with herniated discs and degenerative disc disease collected by the National Cancer Institute Cooperative Tissue Network were analyzed. Differentially expressed genes between more and less dege...

Intervertebral disc degeneration (IDD) is a common orthopedic disease associated with mechanical changes that may result in significant pain. Current treatments for IDD mainly depend on conservative therapies and spinal surgeries that are only able to relieve the symptoms but do not address the cause of the degeneration and even accelerate the degeneration of adjacent segments. This has prompte...

STUDY DESIGN An autograft of costal cartilage was transplanted into the rat intervertebral space in the proximal tail following 2 weeks of simulated degeneration by chondroitinase ABC (CABC). OBJECTIVES The purpose of this study was to evaluate costal cartilage transplantation into a degenerated disc as a possible therapy. SUMMARY OF BACKGROUND DATA Reversal of degenerative disc dehydration...

Cytokines are the main cause of intervertebral disc degeneration. Kartogenin (KGN) is found to protect chondrocytes from cytokines. To explore whether KGN can slow down the degeneration on intervertebral discs following exposure to interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF‑α), the expression of type II collagen (Col II) and aggrecan were detected by immunofluorescence, immunohisto...

OBJECTIVE In the present work we studied the expression of nerve growth associated protein (GAP-43) in a rat model of intervertebral disc degeneration. METHODS 16 healthy adult SD rats, male or female, with an average weight 220g were selected. FluoroGold was injected in L5-L6 disc as the tracer. After 7 days, Freund's adjuvant was then injected to build model of intervertebral disc degenerat...

OBJECTIVE To evaluate the remodeling of the extracellular matrix in intervertebral disc degeneration through the experimental model of intervertebral disc degeneration. METHODS The model of disc degeneration induction, using needle 20G and 360° rotation, was applied for 30 seconds between the 6(th)/7(th), and 8(th)/9(th) coccygeal vertebrae of Wistar rats. The intermediary level, between the ...

Chronic back pain is a global health problem affecting millions of people worldwide and carries significant economic and social morbidities. Intervertebral disc damage and degeneration is a major cause of back pain, characterised by histological and biochemical changes that have been well documented in animal models. Recently there has been intense interest in early intervention in disc degener...
