Observational prospective study. ⋯ The psychometric properties (test-retest reliability, construct validity, and responsiveness) of the French version of the Fear Avoidance Belief Questionnaire are acceptable, and fear, avoidance, and belief can now be assessed in French-speaking patients with low back pain.

Comparative Study
Patterns and trends in opioid use among individuals with back pain in the United States.
Secondary analysis of Medical Expenditure Panel Survey from 1996 to 1999. ⋯ The variation in overall opioid use among individuals with back pain with different sociodemographic characteristics and from different geographic regions suggested an opportunity to improve opioid prescribing patterns. The increase in the use of hydrocodone and oxycodone indicated a need to better assess the efficacy and safety associated with these drugs among individuals with back pain.

A retrospective study of 2 patients with traumatic lumbosacral dislocation. ⋯ Meticulous clinical examination and careful imaging assessment, including CT and MRI, assist an early diagnosis in cases of lumbosacral dislocation. Open reduction and circumferential bony fusion restore segmental stability and painless function.

Historical cohort study. ⋯ Contrary to Functional Capacity Evaluation theory, better Functional Capacity Evaluation performance as indicated by a lower number of failed tasks was associated with higher risk of recurrence. The validity of Functional Capacity Evaluation's purported ability to identify claimants who are "safe" to return to work is suspect.

Clinical and radiologic findings of patients with lumbar spinal stenosis and lumbar disc herniation presenting with neuropathic bladder were prospectively analyzed. ⋯ The prevalence of neuropathic bladder is more significantly associated with dural sac anteroposterior diameter than with the cross-sectional area of dural sac. Therefore, dural sac anteroposterior diameter might be an important factor predicting the existence of neuropathic bladder.
