Comparative Study Clinical Trial
Comparison of the amounts of canal encroachment between semisitting and supine position of computed tomography-myelography for vertebral fractures of the elderly involving the posterior vertebral wall.
A prospective radiographical trial. ⋯ Our study demonstrated that collapse of the nonunited posterior vertebral wall and intracanal protrusion of vertebral fragments would occur simultaneously with axial loading, causing SCE. Computed tomographic scan obtained in semisitting position seems quite useful to evaluate the amount of SCE by an unstable posterior wall.

Serial, cross-sectional, nationally representative surveys of noninstitutionalized US adults. ⋯ Although this study did not explore the relative effectiveness of different ambulatory services, recent increasing costs associated with providing medical care for back and neck conditions (particularly subspecialty care) are contributing to the growing economic burden of managing these conditions.

Comparative Study
Racial differences in the incidence of acute low back pain in United States military service members.
An epidemiological study. ⋯ Race, sex, and age were all found to be significant risk factors for acute low back pain. The highest rates were identified in blacks followed by whites, Hispanics, and American Indian/Alaskan Native, and the lowest rates were identified in Asians/Pacific Islanders. Significant differences in the effect of sex and age were identified between the different racial groups.
