Comparative StudyThe impact of the evolution of invasive surgical procedures for low back pain: a population based study of patient outcomes and hospital utilization.
Low back pain (LBP) is a ubiquitous health problem in Western societies, and while clinical decision making for patients requiring hospitalization for LBP has changed significantly over the past two decades, knowledge of the net impact on patient outcomes and health care utilization is lacking. The aim of this study was to evaluate the effectiveness of changes in the medical control of lumbar back pain in Western Australia in terms of the rate of patient readmission and the total bed days associated with readmissions. ⋯ Between 1980 and 2003, there has been a shift from non-invasive procedural treatments towards invasive techniques both at the time of initial hospitalization and upon subsequent readmission. While overall readmission rates were unaffected, there was a reduction in the number of bed days associated with readmissions.

Although lumbar spondylosis is a major cause of low back pain and disability in elderly people, few epidemiological studies have been performed. The prevalence of radiographic lumbar spondylosis was investigated in a large-scale population study and the association with low back pain was examined. ⋯ This cross-sectional study in a large population revealed a high prevalence of radiographic lumbar spondylosis in elderly subjects. Gender seems to be distinctly associated with KL> or =2 and KL> or =3 lumbar spondylosis, and disc space narrowing with or without osteophytosis in women may be a risk factor for low back pain.

To correlate magnetic resonance (MR) image findings with pain response by provocation discography in patients with discogenic low back pain, with an emphasis on the combination analysis of a high intensity zone (HIZ) and disc contour abnormalities. ⋯ The proposed MR classification is useful to predict a disc with concordant pain. Disc protrusion with HIZ on MR imaging predicted positive discography in patients with discogenic low back pain.
