To evaluate accuracy of needle placement and flow patterns of fluoroscopically guided caudal epidural injections. ⋯ Caudal epidural injections are ideally performed with fluoroscopic guidance as the gold standard for accurate needle placement. However, this does not assure either targeted delivery or accurate placement of the drug.

Comparative Study Clinical Trial Controlled Clinical TrialCorrelation of nerve root pain with dermatomal sensory threshold and back pain with spinal movement in single level lumbar spondylosis.
We studied 27 patients with low back pain and unilateral L5 or S1 spinal nerve root pain. Significant radiological changes were restricted to the symptomatic root level, when compared with controls. Low back and leg pain were graded on a visual analogue scale. ⋯ A further 14 patients with back pain, multilevel nerve root symptoms and radiological changes were also studied. The only correlation found was of low back pain with spinal movement (p < 0.002). We conclude that, in patients with single level disease, dermatomal sensory threshold elevation and restriction of spinal movement are independent correlates of sciatica and low back pain.

Lumbosacral transitional vertebral articulation: evaluation by planar and SPECT bone scintigraphy.
It has been suggested that low back pain (LBP) may arise from lumbosacral transitional vertebral articulation (LSTVA) itself. It is known that bone scintigraphy is a valuable tool for the recognition of pain arising from bone and articular diseases. Therefore we aimed to show planar and SPECT bone scintigraphic findings of LSTVA and compare them with the LBP and X-ray findings. ⋯ The X-ray results showed an association of LBP degenerative changes, and the SPECT results showed a focal, markedly increased, uptake. We conclude that this focal, markedly increased, uptake may show the metabolically active degenerative changes of LSTV articulation and may help to reveal the pain arising from LSTVA. Therefore we propose that bone scintigraphy may be considered for the evaluation of patients with LBP thought to arise from LSTV articulation.

Clinical TrialZygapophysial joint blocks in chronic low back pain: a test of Revel's model as a screening test.
Only controlled blocks are capable of confirming the zygapophysial joints (ZJ) as the pain generator in LBP patients. However, previous workers have found that a cluster of clinical signs ("Revel's criteria"), may be valuable in predicting the results of an initial screening ZJ block. It was suggested that these clinical findings are unsuitable for diagnosis, but may be of value in selecting patients for diagnostic blocks of the lumbar ZJ's. To constitute evidence in favour of a clinical management strategy, these results need confirmation. This study evaluates the utility of 'Revel's criteria' as a screening tool for selection of chronic low back pain patients for controlled ZJ diagnostic blocks. ⋯ "Revel's criteria" are unsuitable as a clinical screening test to select chronic LBP patients for initial ZJ blocks. However, the criteria may have use in identifying a small subset (11%) of patients likely to respond to the initial block (specificity 93%).

This was a pilot study to test the potential effectiveness of intradiscal restorative injection therapy and compare with intradiscal electrothermal therapy (IDET). Thirty-five patients for intradiscal injection and seventy-four for IDET took part in the study. All patients had intractable chronic discogenic low back pain, confirmed by discogram study. ⋯ However, the duration of pain flare-up was notably shorter for restorative injections (8.6 days) than for IDET (33.1 days). Biochemical intradiscal restorative injections may be useful to reduce pain and disability in patients with chronic discogenic low back pain, and have clinically similar efficacy to IDET, but with improved cost-benefit ratio. The results of this study indicate that controlled random prospective comparative studies need to be performed to establish the efficacy of this treatment.
