Comparative Study
Surgical results of lumbar spinal stenosis. A comparison of patients with or without previous back surgery.
This retrospective study was designed to investigate the effects of previous back surgery in patients undergoing surgical procedure for lumbar spinal stenosis. ⋯ Previous back surgery had a highly significant worsening effect on the outcome of patients reoperated on for lumbar spinal stenosis. Not even a very well-established diagnosis of lumbar spinal stenosis, as confirmed by myelography and during surgery, could guarantee as successful a surgical outcome in the repeat surgery patients as that in the singly operated patients.

Descriptive epidemiologic study about magnetic resonance imaging findings in the spine. ⋯ With the exception of endplate irregularities and herniations, the magnetic resonance imaging findings appeared to be associated with the same pathogenic process. The interaction of mechanical factors and spinal structures varies between spinal levels, and the degeneration common in the lower parts of the thoracic and lumbar spine could be an outcome of vulnerability for torsional forces. Some gross guidelines for grouping findings can be drawn from disc level correlations.

A prospective cross-sectional analytic study. ⋯ Computed tomography has no place in the diagnosis of lumbar zygapophysial joint pain.

Two studies evaluated the West Haven-Yale Multidimensional Pain Inventory. This 52-item inventory contains 12 scales divided into 3 parts: 1) interference, support, pain severity, self-control, and negative mood; 2) punishing responses, solicitous responses, and distracting responses; and 3) household chores, outdoor work, activities away from home, and social activities. ⋯ The Multidimensional Pain Inventory meets standards of reliability and convergent validity, and it may be an improvement over current psychometric devices used to this same end.
