Definition/Description[edit | edit source]
It is assumed that Internal Disc Disruption (IDD) is an important cause of low back pain[1]. Crock[2] defined that the affected disc in IDD is rendered painful by changes in its internal structure, while its external appearance remains normal. In particular he reported annular fissures that distort the internal architecture of the disc while the disc externally appears intact and undeformed. This forms the major difference between IDD and disc herniation, which shows a true disruption of the external structure. IDD is not the same as disc degeneration. It’s a condition in which you can speak of a degeneration of the matrix of the nucleus pulposus with radial fissures that penetrate the annulus fibrosus but do not reach the outer lamella[3].
IDD of the lumbar intervertebral disc is often overlooked as possible diagnosis in chronic low back pain[4].

Epidemiology /Etiology[edit | edit source]
Chronic low back pain is the major cause of work-related disability in people under age 45. Only a few of these patients (< 15%) has a discus herniation, which compromise a nerve-root. The majority of this population (85%) suffers from non-neurological back pain and a significant proportion of these patients are assumed to be related to musculoligamentous injury or degenerative changes. Internal disc disruption is a common entity.
30% to 50% of people with chronic low back pain become an IDD diagnosis. In principle, any structure in the spine can be a possible source of pain because it is innervated (rich innervation of the outer third of the annulus fibrosus, extended nerve fibers in the middle third of the annulusi) .
