Comparative Study
Correlation of clinical examination characteristics with three sources of chronic low back pain.
Research has demonstrated some progress in using a clinical examination to predict discogenic or sacroiliac (SI) joint sources of pain. No clear predictors of symptomatic lumbar zygapophysial joints have yet been demonstrated. ⋯ Significant correlations exist between clinical examination findings and symptomatic lumbar discs, zygapophysial and SI joints. The strongest relationships were seen between SI joint pain and three or more positive pain provocation tests, centralization of pain for symptomatic discs and absence of pain when rising from sitting for symptomatic lumbar zygapophysial joints.

Comparative Study
Predicting outcomes of transforaminal epidural injections for sciatica.
Previous studies on epidural injections have focused on efficacy and have not evaluated factors predicting outcomes of epidural injections. ⋯ When controlled for SSDI/workers' compensation, lifting requirements at work, but not working status and radiculopathy, also were associated with outcomes but the association was not as strong. This paper brings into question the utility of offering epidural injections to patients who are on SSDI/workers' compensation and require heavy lifting at work.

Comparative Study
Compliance with clinical practice guidelines in family physicians managing worker's compensation board patients with acute lower back pain.
Family physician compliance with acute lower back pain clinical practice guidelines remains uncertain. ⋯ Recently published clinical practice guidelines regarding the management of patients with acute mechanical lower back pain have not been fully implemented into the patterns of practice of the family physicians.

Partial removal of the nucleus has been shown to decompress herniated discs, relieving pressure on nerve roots and, in some cases, offering relief from disc pain. The nucleoplasty technique builds on earlier surgical approaches that helped validate the strategy of intranuclear tissue removal. Nucleoplasty, a new minimally invasive procedure using patented coblation technology, combines coagulation and ablation for partial removal of the nucleus pulposus to decompress the disc. ⋯ The histologic findings of this study suggest that the nucleoplasty achieves volumetric removal of target disc tissue without overt thermal or structural damage to the adjacent tissues. Further studies in live animals will be needed to assess the effects of nucleoplasty on the annulus, end plate and neural tissues under physiologic conditions, including assessment of cell viability.
