OBJECTIVE To analyze the relationship of the height difference and bone density (BD) of premenopausal and postmenopausal women. METHODS The height values of 191 premenopausal and postmenopausal women were recorded, and the BD values of lumbar vertebrae and hip were detected by double energy X-ray BD detector. RESULTS The lower the height of the postmenopausal women, the less the BD value. T...

Although Behqet's disease (BD) has been known for 2000 years, it was named after the author who described it properly in 1937.1 Recurrent oral or genital aphtosis and uveitis are the main characteristics, but involvement of other organ systems frequently occurs: i.e. the joints, the gastrointestinal tract, the central nervous system and also the vascular system. A 57-year-old man with known BD ...

Working with human subjects to measure internal loadings of lumbar spine is difficult. Numerical modeling makes it possible to study response of spine to a variety of loading conditions. This paper reports the development of a rigid body model of spine using a forward kinematics approach. The model consists of accurate CAD representations of vertebrae interconnected by intervertebral discs prov...

Spontaneous mammary tumors were seen in seven of the 12 breeding female rats aged 2 years. All mammary tumors were diagnosed as mammary dysplasia (MD). Bone mineral contents (BMC) and bone mineral density (BMD) of their lumbar vertebrae and femur were determined using dual energy X-ray absorptiometry (DXA). In rats with MD, body weight (BW), BMD of the lumbar vertebrae and BMC of the femur were...

INTRODUCTION Metastases in the vertebrae of patients with cervical cancer (CeCa) can be difficult to diagnose, and the treatment is palliative in many cases. OBJECTIVES The aim of this study was to assess the ti-me required for diagnosis, the lesion's locoregional extent and the therapeutic schemes applied, in a retrospective series of 58 patients with CeCa and with lumbar spinal metastases. ...

We have already presented two studies of the traditional carrier frame, the seita. In our first study, we reported on seita users supporting loads not on the lumbar vertebrae but on the sacrum. In the second study, we showed that carrying a load on the sacrum was efficient in terms of metabolic rate, muscle activity, cadence and subjective responses. The purpose of this study was to verify the ...

The precise and accurate segmentation of the vertebral column is essential in the diagnosis and treatment of various orthopedic, neurological, and oncological traumas and pathologies. Segmentation is especially challenging in the presence of pathology such as vertebral compression fractures. In this paper, we propose a method to produce segmentations for osteoporotic compression fractured verte...

OBJECTIVES To test whether the position of lumbosacral dermatomes varies in the presence of transitional vertebrae. MATERIAL AND METHODS Fifty consecutive male patients were tested for thoracolumbar and lumbosacral transitional vertebrae by radiography and for the position of the dermatome gap between the lumbar dermatomes L1, L2, L3, and the sacral dermatomes S2 and S3. The dermatome gap was...

The aim of this study is to understand the influences of the social custom of foot binding on female osteoporosis by means of comparing and analyzing the lumbar vertebrae and hip bone mass differences between the foot-binding aged women and unbound women of the same age at Qujing District of Yunnan Province. Of the examined people, 81.37% suffer from osteoporosis on the basis of lumbar vertebra...
