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.

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.

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.

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.
