Comparative Study
Effects of the combined VDS-Zielke and Harrington operation on the frontal rib cage deformity of double major curves in idiopathic scoliosis.
This study analyzed the changes in the frontal plane of the deformed lower rib cage and the scoliosis-related alterations on the spine in patients with double major curve-pattern idiopathic scoliosis. ⋯ Only the anterior VDS-Zielke instrumentation significantly corrects severe spinal deformities, elevates the three lower ribs on the concavity, and increases the droop of the two lower ribs on the convexity in the severe idiopathic double major curve-pattern scoliosis combined operated (Zielke-Harrington). Therefore, the Harrington instrumentation should have only limited use in cosmetic scoliosis surgery and should be replaced with posterior multi-hook instrumentation with a derotation effect.

Lewis Albert Sayre (1820-1900) was an American pioneer in the field of orthopedic surgery, and medicine in general. In addition to much work on spinal and other deformities, Sayre was a founder of what later became the New York University Medical School, where he headed the first department of orthopedics in the United States. Sayre also was a charter member of the American Medical Association and served as its vice president and later as president. He was instrumental in developing the Journal of the American Medical Association, and his extensive work as Resident Physician of New York City led to improvements in sanitation, vaccination, and quarantine for smallpox and cholera.

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.

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.

The technique of obtaining direct coronal computed tomography images of the upper cervical spine is described. ⋯ This technique may replace conventional tomography in assessing of stable upper cervical spine lesions.
