A osteoporotic fracture has become a global health issue that causes tremendous impact on mortality as well as heavy socioeconomic burden. Previous studies suggested that vitamin D may prevent fractures by improving muscle mass as well as via increasing bone density directly. The purpose of the study is to determine that the influence of vitamin D on bone mineral density depends on its effects on muscle mass.We analyzed the data from Korean National Heal...

Type 2 diabetes is associated with fracture risk but, paradoxically, greater bone mineral density. The trabecular bone score (TBS) has been proposed as an index of bone microarchitecture associated with bone quality. This study compared the performance of TBS, bone mineral density (BMD), original and TBS adjusted FRAX scores in the prediction of vertebral fractures (VFs) in diabetic patients. This cross-sectional study enrolled 169 Korean postmenopausal diabetic women. Lateral...

Purpose: The purpose of this study is to analyse regional differences in the microstructural and mechanical properties of the distal femur depending on osteoarthritic changes using micro-images based on finite element analysis.Materials and methods: Distal femur specimens were obtained from ten donors composed of ten women with OA (mean age of 65 years, ranging from 53 to 79). As controls, the normal distal femur was sampled from age and gender matched d...

Objectives: The purpose of this study is to determine the chemical information in trabecular bone by Raman spectroscopy in the osteoarthritic and non-osteoarthritic distal femur.Materials and methods: Distal femur specimens were obtained from ten donors composed of ten womens with OA (mean age of 63 years, ranging from 50 to 76). As controls, the normal distal femur was sampled from age and gender matched donors consisting of ten womens (mean age of 53 y...

Objectives: To compare the incidence of osteoporosis and the related factors among fracture sites in above 50-year-old patients with fractures caused by low-energy trauma.Materials and methods: 714 patients with fracture from low energy trauma were evaluated retrospectively. By the dual-energy X-ray absorptiometry, we measured bone mineral density BMD at lumbar spine and proximal femur, and compared the incidence of osteoporosis, age, sex, BMI, previous ...

Objectives: To determine whether kinds of implants would influence on the radiologic outcomes in the treatment of osteoporotic intertrochanteric fractures.Materials and methods: In this retrospective study, radiologic outcomes of 151 patients with unstable osteoporotic intertrochanteric fractures undergoing surgical treatments were compared based on the types of fixation implants as follows: PFNA (53 cases, group 1), gamma nail 3 (31 cases, group 2), CHS...

Aim: Alendronate enhances bone morphogenetic proteins (BMP)-mediated osteoblast differentiation. A balanced regulation of inhibitors of DNA binding/differentiation (Ids) plays an important role in BMP-induced osteoblast differentiation. However, there are no studies on the possible roles of Id genes in alendronate-induced osteoblast differentiation. This study investigated the effect of alendronate on the expression of Id genes in osteoblast differentiation.<...

Objective: To compare the bone mineral density (BMD) of the lumbar spine and femur in postmenopausal women with cervical and endometrial cancer without bone metastasis with that in normal control postmenopausal women.Methods: We retrospectively analysed the BMD of the lumbar spine and femur using dual-energy X-ray absorptiometry in 130 patients with cervical cancer, 68 patients with endometrial cancer, and 225 healthy controls.Resu...

Objective: Individuals with type 2 diabetes have increased fracture risk despite higher bone mineral density (BMD). There are few studies regarding the effect of diabetes on bone mineral density and hip geometry in Asian population. The aim of this study was to examine the gender-specific influence of diabetes on BMD and hip geometry.Subjects and methods: A total of 1334 subjects (571 men and 763 women) ≥50 years of age were analyzed using data fro...

Introduction: This study aims to assess 25-hydroxyvitamin D—25(OH)D—status in perimenopausal women to analyze its relationships with serum PTH levels and bone mineral density (BMD).Methods: A total of 102 individuals who visited to climacteric clinic in Sanggye paik hospital participated in the study. Serum 25(OH)D and intact parathyroid hormone (PTH) were measured. BMD was determined by dual x-ray absorptiometry (DXA) at lumbar spine, femoral ...
