Human tissue specimens were examined for the presence of neural end-organs under light and electron microscopy. ⋯ These findings suggest that the thoracolumbar fascia may be deficiently innervated in problem back pain patients.

This study analyzed the natural course of cervical spine involvement in rheumatoid arthritis by serial radiographs. ⋯ A progressive pattern of the upper cervical subluxations was clarified. That is, upper cervical lesions progressed from reducible anterior atlantoaxial subluxation to irreducible anterior atlantoaxial subluxation with vertical subluxation. This extent of progression was different with the rheumatoid arthritis subset, which was also related to the development of subaxial subluxation. The most aggressive arthritis classification, a subset with mutilating disease, had the more severe subluxation in both upper and subaxial cervical spine.

Controlled comparison of radiographic interpretive performance based on training and experience. ⋯ These data demonstrate a substantial increase in test results of all radiologists and radiology residents when compared to students and clinicians in both medicine and chiropractic related to the interpretation of abnormal radiographs of the lumbosacral spine and pelvis. Furthermore, the study reinforces the need for radiologic specialists to reduce missed diagnoses, misdiagnoses, and medicolegal complications.

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.
