ReviewThe low back pain syndrome. Diagnostic impact of high-resolution computed tomography.
This article focuses on low back pain which is directly related to the spinal axis and its supporting structures (spondylogenic back pain). This type of back pain is particularly prominent in our society, is frequently managed surgically, and has benefited from most advanced diagnostic imaging with computed tomography.

This study compared 47 patients with chronic low back pain who were involved in personal injury litigation with 33 patients not seeking compensation who were also complaining of low back pain. Pain was assessed using a visual analogue scale and the adjectival check-list of the McGill Pain Questionnaire. Psychological state was assessed using the Zung Depression Scale, the State-Trait Anxiety Inventory, the Eysenck Personality Inventory and the Hostility and Direction of Hostility Questionnaire. ⋯ There was no difference between the two groups on ratings of pain severity or pain description, and no difference on measures of psychological disturbance. Both groups had significant elevations of mean depression, neuroticism, state anxiety and trait anxiety scores when compared with the normal population. It was concluded that there is no support for the claim that personal injury litigants describe their pain as more severe than do non-litigants, and that both groups show similar levels of psychological disturbance.

Our experience, in a group of 25 patients with chronic low back pain, shows that nuclear imaging of the spine with 99mTc-methylene diphosphonate is of no benefit in predicting the sites at which intraarticular facet blocks may be successful.

The effects of epidural injection of local anesthetics and corticosteroids on patients with lumbosciatic pain.
Although epidural cortisone injections are commonly used for treatment of lumbosciatic pain, insufficient critical analysis of the end result can be found in the literature. The present study is a retrospective critical analysis of 367 patients with leg pain who were engaged for a minimum of two weeks or an average of two months in multifaceted conservative management without relief of pain. Injections of 10 cm3 of 0.5% bupivacaine and 100 mg of methylprednisolone were given to inpatients treated by the same anesthesiologist. ⋯ The most favorable results (approaching 70% offd-excellent) were observed in patients with subacute radicular leg pain (of less than three months' duration) and chronic leg pain (of greater than three months' duration) with no prior surgery. Negative myelograms and electromyograms (EMGs), in the absence of reflex or motor deficits on physical examination, also pointed toward optimal results. Those patients with chronic pain who had had prior lumbar spine surgery had the least satisfactory results.
