Population-based, cross-sectional, mailed survey. ⋯ Low-intensity/low-disability low back pain is a common problem in the general population. Approximately 11% of the adult population studied had been disabled by low back pain in the previous 6 months.

Fifty-seven patients with dens fractures were identified from 1986 to 1996 at the authors' institution. Forty-six were available for reevaluation by two independent observers with a mean follow-up period of 26 months. ⋯ Patients over 60 years of age with a dens fracture had a higher complication rate and lower cervical range of motion when treated conservatively with a halo. Final functional outcome and overall pain levels, however, did not differ significantly by age group or treatment modality.

Randomized Controlled Trial Comparative Study Clinical Trial
One-year follow-up comparison of the cost and effectiveness of chiropractic and physiotherapy as primary management for back pain. Subgroup analysis, recurrence, and additional health care utilization.
A randomized trial was conducted in which patients with back and neck pain, visiting a general practitioner, were allocated to chiropractic or physiotherapy. ⋯ Effectiveness and costs of chiropractic or physiotherapy as primary treatment were similar for the total population, but some differences were seen according to subgroups. Back problems often recurred, and additional health care was common. Implications of the result are that treatment policy and clinical decision models must consider subgroups and that the problem often is recurrent. Models must be implemented and tested.

Randomized Controlled Trial Clinical Trial
The ability of lumbar medial branch blocks to anesthetize the zygapophysial joint. A physiologic challenge.
Randomized, controlled, single blinded study. ⋯ There was a significant effect of 2% lidocaine (versus saline) medial branch injections on anesthetization of the zygapophysial joint when venous uptake was avoided during these injections. When properly performed, lumbar medial branch blocks successfully inhibit pain associated with capsular distention of the lumbar zygapophysial joints at a rate of 89%.

Randomized Controlled Trial Clinical Trial
Can it be predicted which patients with chronic low back pain should be offered tertiary rehabilitation in a functional restoration program? A search for demographic, socioeconomic, and physical predictors.
A prospective clinical trial was conducted that involved six groups of patients with chronic low back pain selected from a large cohort (N = 816). ⋯ Different factors can be identified as predictive of outcome in a functional restoration program, but most of these factors were also shown to predict success for shorter control outpatient programs or of no treatment.
