STUDY DESIGN A descriptive computed tomography (CT) study of the ligamentum flavum (LF) thickness in individuals with normal and stenotic lumbar spines. OBJECTIVE To establish standards for normal and pathologic range of LF thickness and its asymmetry as indicated in CT images and to examine its association with vertebral body size, age, and gender.

As life expectancy increases, degenerative lumbar spinal stenosis (DLSS) becomes a common health problem among the elderly. DLSS is usually caused by degenerative changes in bony and/or soft tissue elements. The poor correlation between radiological manifestations and the clinical picture emphasizes the fact that more studies are required to determine the(More)
Discovering the nature of sacral orientation is of considerable anthropological importance. Therefore, this study aims at presenting a new anthropologically based definition for sacral anatomical orientation (SAO) angle, establishing standards of SAO for human population; examining the relationship between pelvic incidence (PI) and SAO; and associating SAO(More)
BACKGROUND Professional drivers have been found to be at high risk for developing low back pain. However, the exact reasons are poorly understood. OBJECTIVES To assess the prevalence of LBP among Israeli professional urban bus drivers, and evaluate the association between LBP in drivers and work-related psychosocial and ergonomic risk factors. METHODS A(More)
Little data are available on the growth and development of young female dancers. The objective of this study was to determine whether the body structure and adipose tissue distribution of dancers aged 8-16 years differ from that of non-dancer girls. Our cross-sectional study included a group of 1,482 female dancers, aged 8-16 years, and a control group of(More)
STUDY DESIGN Quantitative lumbar magnetic resonance imaging (MRI) measurements in children were taken twice and analyzed for intra- and intertester reproducibility. OBJECTIVE To evaluate the reproducibility of a variety of lumbar quantitative measurements taken from MRIs of children from the general population. SUMMARY OF BACKGROUND DATA The(More)
Opinions differ as to the exact mechanism responsible for spondylolysis (SP) and whether individuals with specific morphological characteristics of the lumbar vertebral neural arch are predisposed to SP. The aim of our study was to reveal the association between SP and the architecture of lumbar articular facets and the inter-facet region. Methods: Using a(More)
STUDY DESIGN Thoracolumbar facet and interfacet linear dimensions were measured and analyzed. OBJECTIVE To characterize and analyze the thoracolumbar facet and interfacet size and shape in relation to gender, ethnic group, and age and to detect the extent of normal facet tropism along the thoracolumbar spine. SUMMARY OF BACKGROUND DATA Knowledge on(More)
STUDY DESIGN The shape and orientation of the thoracic and lumbar zygapophyseal facets at the T1-L5 level in children were measured and analyzed. OBJECTIVE To detect the pattern of zygapophyseal facet asymmetry in the thoracic and lumbar spines in children. SUMMARY OF BACKGROUND DATA Whereas many studies have defined the pattern of zygapophyseal facet(More)
STUDY DESIGN A descriptive study of the sacral anatomic orientation (SAO) and its association with pelvic incidence (PI). OBJECTIVE To introduce the concept of SAO, establish a method for measuring it, and evaluate its association with pelvic orientation. SUMMARY OF BACKGROUND DATA Pelvic orientation (PO) is considered a key factor in spinal shape and(More)
