Clinical Trial
Results of sacroiliac joint double block and value of sacroiliac pain provocation tests in 54 patients with low back pain.
This prospective study consisted of the evaluation of a double sacroiliac block in patients with low back pain. ⋯ The present study suggests the sacroiliac joint is an uncommon but real source of low back pain. The accuracy of some of the presumed "sacroiliac pain provocations tests" is questioned.

Clinical Trial
The outcome of posterolateral fusion in highly selected patients with discogenic low back pain.
A prospective analysis of the clinical outcome of a consecutive series of patients treated with posterior lumbar arthrodesis. Preoperative data were collected retrospectively by chart review. ⋯ Posterolateral intertransverse fusion can be used to successfully manage chronic discogenic back pain. However, patient selection remains a challenge, and successful outcome appears to be limited in the subset of patients receiving worker's compensation and those chronically disabled. Prospective and randomized study with objective pain criteria, independent review, and patient-oriented outcome is recommended.

Influence of previous pain experience on the episode incidence of low back pain: results from the South Manchester Back Pain Study.
A pathological cause cannot be identified for most new episodes of low back pain (LBP) presenting to the general practitioner. One important potential influence on susceptibility is previous pain experience. To accurately investigate the contribution of this phenomenon to the onset of new episodes of LBP a prospective population study is required. ⋯ In those currently free of LBP a previous history of the symptom substantially increases the risk of a further episode, with pain in other sites an equally strong independent predictor of subsequent LBP.

Little is known about substance use and substance use disorders among primary care patients with chronic back pain. This study compared groups of patients with and without chronic back pain for the prevalence of substance use and substance use disorders. It also assessed the temporal relationship between the onset of chronic back pain and that of substance use disorders. ⋯ Chronic back pain did not connote special risk for current substance use disorders.
