Review Meta Analysis
Effectiveness of conservative treatments for the lumbosacral radicular syndrome: a systematic review.
Patients with a lumbosacral radicular syndrome are mostly treated conservatively first. The effect of the conservative treatments remains controversial. To assess the effectiveness of conservative treatments of the lumbosacral radicular syndrome (sciatica). ⋯ Because several trials indicated no evidence of an effect it is not recommended to use corticosteroid injections and traction as treatment option. Whether clinicians should prescribe physical therapy, bed rest, manipulation or medication could not be concluded from this review. At present there is no evidence that one type of treatment is clearly superior to others, including no treatment, for patients with a lumbosacral radicular syndrome.

Intervertebral disc organ culture has the capacity to control mechanical and chemical boundary conditions while keeping the tissue largely intact, and allowing interventions that would be impossible or unethical on animal studies. Recent studies on ex vivo organ culture has mostly involved small animals, or been limited to development and validation studies. In this study, bovine caudal discs were used. ⋯ No significant differences were seen in viability of the outer annulus region with time, or in any loading groups. We conclude that our system is capable of keeping bovine caudal discs alive for at least 8 days without significant changes in GAG content, or cell metabolism, and that static loading was slightly better able to maintain cell viability than diurnal loading. This system offers promise for the future studies on large intervertebral discs requiring measurements of multiple mechanical and biological dependent variables on the same tissue.

Since many years we routinely use diagnostic selective nerve root blocks (SNRB) at our department when evaluating patients with cervical radiculopathy. Frequently patients who also presented with headache reported that the headache disappeared when the nerve root responsible for the radicular pain was blocked with local anaesthetics. Headache has been described as a companioning symptom related to cervical radiculopathy but has never before been evaluated with SNRB performed in the lower cervical spine. ⋯ After selective nerve root block, 59% of the patients with headache reported 50% or more reduction of headache and of these 69% reported total relief. A significant correlation was seen between reduced headache intensity and reduced pain in the neck, shoulder and arm. The result indicates that cervical root compression from degenerative disease in the lower cervical spine producing radiculopathy might also induce headache.

To better understand the role of facet joint degeneration in chronic neck and back pain epidemiological and morphological data are needed. For the cervical spine, however, such data are rare. Therefore, the aim of this study was to determine the degree of cartilage degeneration of cervical facet joints with respect to spinal level and age, to investigate whether any region of the joint surface is more often affected by degeneration and to determine the localisation of osteophytes. ⋯ In conclusion, the prevalence of cervical facet joint degeneration is probably very high in individuals aged 50 years and more, with a tendency to increase in severity with age. All levels of the middle and lower cervical spine were affected to almost the same degree, whereas in the lumbar spine an increase in degeneration towards the lower levels was reported. Also, in the cervical spine in most cases the cartilage was evenly degenerated all over the joint surface while in the lumbar spine certain regions were reported to be affected predominantly.

The purpose of this study was to analyze the association between the severity of inflammatory endplate changes (Modic) on MRI and the clinical response to intradiscal injection of corticosteroids (IDIC) in chronic low back pain (LBP). A total of 74 patients with LBP and inflammatory Modic changes who showed no response to 3-month conservative treatment received lumbar IDIC. Two spine specialists and a radiologist assessed independently the endplate marrow changes of the injected discs. ⋯ At 3 and 6 months, IDIC tended to be more effective in the Modic I and Modic I-2 groups but not significantly. No complications such as infection or hematoma were reported. IDIC could be a short-term efficient treatment for patients with chronic LBP and predominantly inflammatory endplate changes when conservative treatments have failed.
