Lumbar Disk Herniations: Another Dragon to Slay

Chiroweb.com By Anthony Rosner, PhD, LLD [Hon.], LLC Along with the noteworthy advances of chiropractic research and documentation over the past 20 years have unfortunately come a number of highly publicized slings and arrows. Many are without sufficient basis, and there are enough to conjure up visions of St. Sebastian. One particularly troublesome impediment is […]

Intervertebral discs from spinal nondeformity and deformity patients have different mechanical and matrix properties

Kevin K. Cheng, PhD The Spine Journal: Available online 16 November 2013: In Press Abstract Background context It is well-established that disc mechanical properties degrade with degeneration. However, prior studies utilized cadaveric tissues from donors with undefined back pain history. Disc degeneration may present with pain at the affected motion segment, or it may be […]

An evidence-based clinical guideline for the diagnosis and treatment of lumbar disc herniation with radiculopathy

D. Scott Kreiner, MD Published Online: November 18, 2013 Background context The objective of the North American Spine Society’s (NASS) Evidence-Based Clinical Guideline for the Diagnosis and Treatment of Lumbar Disc Herniation with Radiculopathy is to provide evidence-based recommendations to address key clinical questions surrounding the diagnosis and treatment of lumbar disc herniation with radiculopathy. The guideline […]

Anterior herniation of lumbar disc induces persistent visceral pain: discogenic visceral pain: discogenic visceral pain

Chin Med J (Engl). 2013;126(24):4691-5. Tang YZ, Shannon ML, Lai GH, Li XY, Li N, Ni JX Abstract BACKGROUND: Visceral pain is a common cause for seeking medical attention. Afferent fibers innervating viscera project to the central nervous system via sympathetic nerves. The lumbar sympathetic nerve trunk lies in front of the lumbar spine. Thus, […]

Associations between Lumbosacral Transitional Anatomy Types and Degeneration at the Transitional and Adjacent Segments

Nadja A. Farshad-Amacker, MD The Spine Journal:Available online 8 November 2013: In Press Abstract Background The relation between specific types of lumbosacral transitional vertebra and the degree of degeneration at and adjacent to the transitional level is unclear. It is further unknown whether the adjacent cephalad segment to a transitional vertebra is prone to greater […]

Disc degeneration and chronic low back pain

An association which becomes nonsignificant when endplate changes and disc contour are taken into account Francisco M. Kovacs Neuroradiology:  November 2013 Abstract Introduction The objective of this study was to assess the association between severe disc degeneration (DD) and low back pain (LBP). Methods A case–control study was conducted with 304 subjects, aged 35–50, recruited […]

MRI for diagnosing lumbar spinal pathology in adult patients with low back pain or sciatica

In conclusion, these poor results show that non-negligible numbers of LBP patients will be incorrectly diagnosed when MRI is used in isolation.

Investigators find gene influences risk of lumbar disc degeneration

October 21, 2013 A genetic variation found after searching the genome of families in China, Japan and Finland with a history of lumbar disc degeneration has been linked to an increased susceptibility to the disease, according to researchers from the University of Hong Kong. “Our finding provides a key functional link of this variant form […]

Innervation of pathologies in the lumbar vertebral end plate and intervertebral disc

Aaron J. Fields, PhD Abstract Background context Magnetic resonance imaging (MRI) has limited diagnostic value for chronic low back pain because of the unclear relationship between any anatomic abnormalities on MRI and pain reported by the patient. Assessing the innervation of end plate and disc pathologies—and determining the relationship between these pathologies and any abnormalities […]

Intervertebral disc degeneration: evidence for two distinct phenotypes.

The structural defects which initiate the two processes both act to decompress the disc nucleus, making it less likely that the other defect could occur subsequently, and in this sense the two disc degeneration phenotypes can be viewed as distinct.

Do intervertebral discs degenerate before they herniate, or after?

Bone Joint J. 2013 Aug;95-B(8):1127-33. doi: 10.1302/0301-620X.95B8.31660. Lama P, Le Maitre CL, Dolan P, Tarlton JF, Harding IJ, Adams MA. Abstract The belief that an intervertebral disc must degenerate before it can herniate has clinical and medicolegal significance, but lacks scientific validity. We hypothesised that tissue changes in herniated discs differ from those in discs […]
