Human Skeleton: The human skeleton consists of over 200 bones of different sizes and shapes that play a variety of roles in maintaining our health and well-being. Bones provide the basic structural framework for our muscles and allow us to stand upright and move about. Bones also encase and protect sensitive organs of the body such as the brain, heart, spinal cord and eyes from injury from exte...

To determine the factors in daily physical activity that influence the mineral density of the calcaneus, we recorded walking steps and the type and duration of exercise in 43 healthy 26-to 51-yr-old men. Areal (g.cm-2) calcaneal bone mineral density (CBMD) was measured by single energy x-ray densitometry (SXA, Osteon, Inc., Wahiawa, HI). Subjects walked a mean (+/- SD) of 7902 (+/- 2534) steps ...

Osteoporosis is the most common metabolic disease with significant impact on the morbidity and mortality of affected patients. Osteoporosis has a significant impact on the economy worldwide. The aim of this study was to find out whether heel ultrasound is as good as central bone densitometry scanning in diagnosing osteoporosis in patients who are at high risk of osteoporosis. This was a prospec...

INTRODUCTION The aim of this study is to improve the assistance given to patients under treatment with aromatase inhibitors in order to prevent secondary osteoporosis through the planning of an awareness programme for the oncologist and offering a facilitated treatment path. MATERIALS AND METHODS Thirty-nine postmenopausal women treated with aromatase inhibitors for breast cancer were selecte...

BACKGROUND Osteoporosis (OP) is a metabolic bone illness that may complicate celiac disease (CD). It can lead to devastating consequences because of low bone mass and fragility fractures. PURPOSE To study the OP prevalence in a group of Brazilian patients with CD and the value of a gluten free diet (GFD). METHODS Retrospective study of celiac female patients from a single University Center ...

This study reviewed the results of a cementless anatomical femoral component to give immediate post-operative stability, and with a narrow distal section in order not to contact the femoral cortex in the diaphysis, ensuring exclusively metaphyseal loading. A total of 471 patients (601 hips) who had a total hip replacement between March 1995 and February 2002 were included in the study. There we...

Introduction Over the past few decades, a number of methods have been developed for the in vivo determination of bone density. The most important of these methods are based on measuring the attenuation (reduction in intensity) of a beam of either electromagnetic radiation (in the form of X-rays or gamma rays) or ultrasound when it passes through bone; in the latter case, the measurement of velo...

The implanting of a hip endoprosthesis changes the mechanical loading in a hip. The changing in loading causes bone remodeling. The loss of loading leads to bone atrophy, whereas an increase in loading leads to hypertrophy of the bones. We investigated the relationship between the clinical result and change in periprosthetic bone mineral density. The Harris hip score was used to measure the cli...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...
