Abstract

BACKGROUND:

Because previous studies have suggested that motorized non-surgical spinal decompression can reduce chronic low back pain (LBP) due to disc degeneration (discogenic low back pain) and disc herniation, it has accordingly been hypothesized that the reduction of pressure on affected discs will facilitate their regeneration. The goal of this study was to determine if changes in LBP, as measured on a verbal rating scale, before and after a 6-week treatment period with non-surgical spinal decompression, correlate with changes in lumbar disc height, as measured on computed tomography (CT) scans.

METHODS:

A retrospective cohort study of adults with chronic LBP attributed to disc herniation and/or discogenic LBP who underwent a 6-week treatment protocol of motorized non-surgical spinal decompression via the DRX9000 with CT scans before and after treatment. The main outcomes were changes in pain as measured on a verbal rating scale from 0 to 10 during a flexion-extension range of motion evaluation and changes in disc height as measured on CT scans. Paired t-test or linear regression was used as appropriate with p < 0.05 considered to be statistically significant.

RESULTS:

We identified 30 patients with lumbar disc herniation with an average age of 65 years, body mass index of 29 kg/m2, 21 females and 9 males, and an average duration of LBP of 12.5 weeks. During treatment, low back pain decreased from 6.2 (SD 2.2) to 1.6 (2.3, p < 0.001) and disc height increased from 7.5 (1.7) mm to 8.8 (1.7) mm (p < 0.001). Increase in disc height and reduction in pain were significantly correlated (r = 0.36, p = 0.044).

CONCLUSIONS:

Non-surgical spinal decompression was associated with a reduction in pain and an increase in disc height. The correlation of these variables suggests that pain reduction may be mediated, at least in part, through a restoration of disc height. A randomized controlled trial is needed to confirm these promising results. CLINICAL TRIAL REGISTRATION NUMBER: NCT00828880.

Let’s have a look a the causes of low back pain and how it could be related to degenerative disc disease and herniated discs.

  • common complaint among adults
  • lifetime prevalence in working population up to 80%
  • 60% experience functional limitation or disability
  • second most common reason for work disability
  • despite advances in imaging and surgical techniques LBP prevalence and its cost are relatively unchanged
  • 90% people age >50 have Degenerative Disc Disease
  • Large disc herniation does NOT always need surgery
  • Neurologic loss is NOT an absolute indication for surgery
  • Small disc bulge is NOT always normal
  • Surgery does not have an 80% success rate
  • Conservative treatment is reversible. Surgery is not.

Disc Degeneration

Normal Vs Disc Degeneration - Clic to enlarge

Disc degeneration (arthrosis)

  • Changes in hydrostatic pressure
  • Lack of oxygen
  • Lack of glucose
  • Changes in pH levels
  • Death of proteoglycans

If the cells of the disc failed to get proper nutrients – such as oxygen, or glucose – or if the pH level of the disc drops (because waste is not being diffused out of the disc and it becomes anaerobic), disc cells would die and stop producing the vital proteoglycan aggregates. The disc loses its water content (dehydrates) and loses its hydrostatic pressure (osmotic pressure).

Symptoms of lumbar disc disease are the result of either herniation of the nucleus pulposus through a mechanically weak annulus fibrosis or from tearing of the annulus itself. This can lead to Radiculopathy from nerve root compression and/or Radiculitis – an inflammatory process affecting nerve roots or the spinal cord.  Herniation is thought to be the result of a defect in the annulus fibrosis, most likely the result of excessive stress applied to the disc.


Herniated disc
[FMP]https://www.sosherniateddisc.com/wp-content/uploads/2010/09/herniateddiscL5.flv[/FMP]

Three types of annular tears:

  1. Rim lesion – horizontal tearing of the very outer fibers of the disc near their attachments into the ring apophysis;
  2. Concentric tear – splitting apart of the lamellae of the annulus in a circumferential direction
  3. Radial tear – horizontal or obliquely horizontal tears

We are looking for new partners with an existing chiropractic clinic in Trois-Rivières, Drummundville, Longueuil and Sherbrooke to open up new spinal decompression clinics.
