Review paper of outcome studies among primary care back pain patients. ⋯ Results from existing studies suggest that back pain among primary care patients typically runs a recurrent course characterized by variation and change, rather than an acute, self-limiting course.

This paper is based on a review, analysis, and discussion of the extensive literature on indications, technique, and complications of discectomy (macro and micro) for lumbar disc herniation. Outcomes for lumbar discectomy for disc herniation depend on patient selection. ⋯ A review of the literature reveals success rates for lumbar discectomy ranging from 80-96%. The outcome of lumbar discectomy does not appear to be affected by the use of a microscope and depends more on patient selection than on surgical technique.

Review Comparative Study
Spinal manipulation for low back pain. An updated systematic review of randomized clinical trials.
Systematic review of randomized clinical trials. ⋯ The efficacy of spinal manipulation for patients with acute or chronic low back pain has not been demonstrated with sound randomized clinical trials. There certainly are indications that manipulation might be effective in some subgroups of patients with low back pain. These impressions justify additional research efforts on this topic. Methodologic quality remains a critical aspect that should be dealt with in future studies.

Multicenter Study Clinical Trial
The Quebec Task Force classification for Spinal Disorders and the severity, treatment, and outcomes of sciatica and lumbar spinal stenosis.
A prospective cohort study of patients in Maine with sciatica and lumbar spinal stenosis treated surgically and nonsurgically. ⋯ For patients with sciatica, the Quebec Task Force classification was highly associated with the severity of symptoms and the probability of subsequent surgical treatment. Nonsurgically treated patients in Quebec Task Force classification categories reflecting nerve root compression had greater improvement than those with pain symptoms alone. Among surgical patients, the Quebec Task Force classification was not associated with outcome. These results provide validation for the classification and its wider adoption. Nonetheless, improved diagnostic classifications are needed to predict outcomes better in patients with sciatica who undergo surgery.

This is the second of two papers that systematically review available scientific evidence on the causes of disability from occupational low back pain, and the effectiveness of interventions to prevent it after its onset (secondary prevention). This paper reviews the national history of how back pain and the risk factors for its extension into chronic disability, followed by a critical summary of intervention studies attempting to reduce the duration of this disability, and to evaluate the results.
