چکیده
Acta Ortop Bras. 2009; 17(1):46-9 AbStrACt The authors suggest an analysis of the degeneration of intervertebral disks on human cadavers using magnetic resonance imaging. Nine lumbar spines were collected from fresh human cadavers and resonance images were captured. The images were analyzed and classified according to the degeneration grades, with the authors proposing a subdivision of type IV into IV-a and IV-b. Forty-four intervertebral disks were analyzed and authors found the following distribution: 4,5% type I; 40,9% type II; 32%

In Vivo Mouse Intervertebral Disc Degeneration Model Based on a New Histological Classification
Although human intervertebral disc degeneration can lead to several spinal diseases, its pathogenesis remains unclear. This study aimed to create a new histological classification applicable to an in vivo mouse intervertebral disc degeneration model induced by needle puncture. One hundred six mice were operated and the L4/5 intervertebral disc was punctured with a 35- or 33-gauge needle. Micro-...
متن کاملA Dose-response relationship between severity of disc degeneration and intervertebral disc height in the lumbosacral spine.
INTRODUCTION Varied definitions of disc pathology exist in the literature. Magnetic Resonance Imaging (MRI) classification systems incorporate several qualitative features including disc appearance, the distinction between the nucleus and the annulus, signal intensity and intervertebral disc height. The lack of a continuous measure has made it difficult to sensitively examine degenerative disc ...
متن کاملCorrelations between radiographic, magnetic resonance and histological examinations on the degeneration of human lumbar intervertebral discs.
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...
متن کاملExperimental model of intervertebral disc degeneration by needle puncture in Wistar rats
Animal models of intervertebral disc degeneration play an important role in clarifying the physiopathological mechanisms and testing novel therapeutic strategies. The objective of the present study is to describe a simple animal model of disc degeneration involving Wistar rats to be used for research studies. Disc degeneration was confirmed and classified by radiography, magnetic resonance and ...
متن کاملMeasuring Dimensions of Lumbar Intervertebral Discs in Normal Subjects
Introduction: Disc degeneration is a natural aging process characterized by changes in appearance and chemical structure of the disc. This degeneration leads to back pain. In regard to the limitation of current therapeutical methods for patients with degenerated discs, arthroplasty has been suggested as an alternative method. To manufacture artificial discs for Iranians, determining normal lumb...
