Comparative Study
Lumbar-hip flexion motion. A comparative study between asymptomatic and chronic low back pain in 18- to 36-year-old men.
The amount of lumbar and hip flexion and the relative contribution within movement during standing forward bending was recorded on a group of asymptomatic men and a group of men with a history of chronic low back pain. ⋯ When assessing the relative motion of the lumbar spine and hips in standing forward flexion, there was measurable difference between asymptomatic men and a group of chronic low back pain patients. In particular, two subgroups of individuals with chronic low back pain appeared; one moved relatively similarly to the asymptomatic group, whereas the other sub-group demonstrated reduced hip mobility. These findings indicate the importance of assessing the lumbar and hip flexion motion in chronic low back pain patients to determine if a movement abnormality is present.

Simple and reliable diagnostic aids need to be available for clinicians to consider sacroiliac joint dysfunction in the differential diagnosis of low back pain. The Fortin finger test was used as a means to identify patients with low back pain and sacroiliac joint dysfunction. Provocation-positive sacroiliac joint injections were used to ratify or refute the applicability of this new clinical sign for identification of patients with sacroiliac joint dysfunction. ⋯ A subset of 10 individuals underwent additional evaluation to exclude the possibility of confounding discogenic or posterior joint pain sources. All 10 patients had no indication of either discogenic or zygapophyseal joint pain generators. These results indicate that positive findings of the Fortin finger test, a simple diagnostic measure, successfully identifies patients with sacroiliac joint dysfunction.

The Agency for Health Care Policy and Research (AHCPR) has recently published guidelines for the management of patients with acute low back pain, which include recommendations for the use of lumbar radiographs, based on the identification of "red flags" for fractures, tumors, or infections. The purpose of this study was to evaluate the potential impact of these guidelines in patients with new episodes of low back pain seen in primary care settings. ⋯ The implementation of the AHCPR guidelines for the initial use of radiographs in patients with low back pain may increase utilization and economic costs. A more restricted and cost-efficient set of guidelines should be proposed.

Low back pain is the most expensive condition in industrialized countries. Approximately 65-80% of the population will be afflicted with low back pain at some point during their life. Low back pain has many causes and can originate from any of several pain-sensitive foci, among which are facet joints, sacroiliac joint, muscle and ligaments. ⋯ If used, their potential benefit for the individual case needs to be carefully weighed. They should be used to facilitate more aggressive conservative care and not as an isolated treatment. Certainly, if response to corticosteroids does not occur after the first injection, no further administration of corticosteroids is indicated.
