Purpose: To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. Materials and Methods: We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eighty-six patients remained after excluding women less than 40 years of...

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...

Back pain is common and costly. While a general scene of back pain related practice in China remains unknown, there are signs of excessive use of lumbar spine magnetic resonance (MR). We retrospectively studied 3107 lumbar spine MRIs in Eastern China to investigate the appropriateness of lumbar spine MR use. Simple back pain is the most common chief complaint for ordering a lumbar MR study. Onl...

Conventional radiography has been for decades the standard method of evaluation for cervical spine trauma patients. However, currently available helical multidetector CT scanners allow multiplanar reconstruction of images, leading to increased diagnostic accuracy. The purpose of this study was to determine the relative benefit/risk ratio between cervical spine CT and cervical spine radiography ...

Arthritis is the common term used to describe pathological changes of joints and adjoining parts of the bone. Several types of arthritis commonly affect the spine. Osteoarthritis, a non-inflammatory type of arthritis, most often affects the cervical spine and the lumbar spine. Neck pain, limited neck and head motion, low back pain, and limited flexibility of the low back can result from progres...

background: alkaptonuria is a rare genetic disease leading to the accumulation of homogentesic acid in joint and ear cartilage, sclera and some other tissues causing significant morbidity in these patients. in this paper, we report three cases of alkaptonuria among the family or household members. case presentation: a 51-year-old man with mechanical low back and knee pain was referred to rheuma...

The purpose of this study was to determine whether lower body negative pressure (LBNP) treadmill exercise maintains lumbar spinal compressive properties, curvature, and back muscle strength after 28 days of 6 degrees head-down tilt (HDT) bed rest (BR). We hypothesize that LBNP treadmill exercise will maintain lumbar spine compressibility, lumbar lordosis and back muscle strength after 28 days o...

CONTEXT Knee bending during tests of lumbar forward bending (FB) may introduce confounding variability. Precluding bending at the knees has, therefore, long been standard protocol to produce valid and reproducible results. However, there is limited research on cervical spine bending as a confounding variable in whole trunk and lumbar FB. OBJECTIVE To examine the role of cervical spine bending...

OBJECTIVES To investigate the relation with a case-control study between symptomatic osteochondrosis or spondylosis of the lumbar spine and cumulative occupational exposure to lifting or carrying and to working postures with extreme forward bending. METHODS From two practices and four clinics were recruited 229 male patients with radiographically confirmed osteochondrosis or spondylosis of th...

OBJECTIVE This report presents bone measurement data from dual-energy X-ray absorptiometry scans of the lumbar spine and proximal femur for persons aged 8 years and over from the National Health and Nutrition Examination Survey (NHANES) 2005-2008. METHODS Means, standard deviations, and selected percentiles were calculated for the proximal femur and lumbar spine (total and subregions) by sex,...
