Vital to the study of past populations and an important phase in executing a forensic anthropological examination is the determination of skeleton sex. The aim of this study is to present an easy and reliable criterion for sexing the skeleton. The ilium and sacrum of 2845 skeletons were examined for new bone formation and for bridging/fusion in/across the(More)
STUDY DESIGN Interrater reliability. OBJECTIVES (1) To examine the interrater reliability of an existing clinical prediction rule (CPR) to predict the success of lumbar stabilization exercises (LSE), and (2) to examine the interrater reliability of 4 clinical tests that may be useful in determining the need for LSE. BACKGROUND Physical therapists(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)
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)
This study was designed to characterize the vertebral body (VB) shape, focusing on vertebral wedging, along the thoracic and lumbar spine, and to look for shape variations with relation to gender, age, and ethnicity. All thoracic and lumbar (T1-L5) dissected vertebrae of 240 individuals were measured and analyzed by age, gender, and ethnicity. A 3D(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)
Although Schmorl’s nodes (SNs) are a common phenomenon in the normal adult population, their prevalence is controversial and etiology still debatable. The objective was to establish the spatial distribution of SNs along the spine in order to reveal its pathophysiology. In this study, we examined 240 human skeleton spines (T4-L5) (from the Hamann–Todd(More)
STUDY DESIGN Orientation of the lumbar articular facets at the L1-L5 level was measured and analyzed. OBJECTIVE To characterize the relationship between lumbar facet orientation and isthmic spondylolysis. SUMMARY OF BACKGROUND DATA Whereas many studies have explored the relationship between facet orientation in the transverse plane and various spinal(More)
