Despite the increasing recognition of the functional and clinical importance of lumbar lordosis, little is known about its description, particularly in Egypt. At the same time, magnetic resonance imaging (MRI) has been introduced as a noninvasive diagnostic technique. The aim of this study was to investigate the anatomy of the lumbar lordosis using midsagittal MRIs. Normal lumbar spine MRIs obt...

Objectives: An increase in anterior pelvic tilt is often assumed to result from short hip flexor muscles. Such altered postural alignment may the stress on lumbar spine and has been shown be a characteristic of specific low back pain populations. However, there minimal research investigating link between muscle length inclination/lumbar lordosis relaxed standing. Therefore, this study sought un...

There is a lack of quantitative evidence for spinal postures that are advocated as 'ideal' in clinical ergonomics for sitting. This study quantified surface spinal curves and examined whether subjects could imitate clinically 'ideal' directions of spinal curve at thoraco-lumbar and lumbar regions: (i) flat - at both regions (ii) long lordosis - lordotic at both regions (iii) short lordosis - th...

BACKGROUND Prone lying knee flexion (PLKF) is one of the clinical tests used for assessment of the lumbo-pelvic movement pattern. Considerable increase in lumbar lordosis during this test has been considered as impairment of movement patterns in lumbar-pelvic region. However, no study has directly evaluated the change in lordosis during active PLKF test in subjects with low back pain (LBP). The...

abstract study design . a retrospective radiographic review was undertaken in patients treated for ais. objectives. to determine the most important preoperative factors that affect on postoperative junctional kyphosis complication. methods sagittal spine profilewere measured on the standing radiographs before, after and in the last follow-up visit of the operated patients for ais. the following...

Introduction The incidence of degenerative osteoarthritis of the hip or knee joint and degenerative changes in the lumbar spine both increased with age. It was reported that lumbar lordosis and sacral inclination were related to the degree of extension of the hip, there may be an associated loss of lumbar lordosis. Many patients also have degenerative changes of the knee with loss of extension ...

BACKGROUND The sagittal alignment of the spine changes depending on body posture and degenerative changes. This study aimed to observe changes in sagittal alignment of the lumbar spine with different positions (standing, supine, and various sitting postures) and to verify the effect of aging on lumbar sagittal alignment. METHODS Whole-spine lateral radiographs were obtained for young voluntee...
