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...

Epidermal growth factor-like repeats and discoidin I-like domains 3 (Edil3) is an extracellular matrix protein that contains Arg-Gly-Asp (RGD) motif to bind to integrins. Recently it has been reported that Edil3 is involved in various biological processes, including angiogenesis and cellular differentiation. This study was to explore the role of Edil3 in osteoblast differentiation and an underlining molecular mechanism. When MC3T3E1 cells were cultured with osteogenic medium, ...

Rheumatoid arthritis (RA) and osteoarthritis (OA), two common types of arthritis, affect the joints mainly by targeting the synovium and cartilage. Increasing evidence indicates that a significant network connects synovitis and cartilage destruction during the progression of arthritis. We recently demonstrated that hypoxia-inducible factor (HIF)-2α causes RA and OA by regulating the expression of catabolic factors in fibroblast-like synoviocytes (FLS) or chondrocytes. To ...

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 ...

Objective: We analyze changes of spine BMD and hip BMD after total knee replacement (TKR) according to osteoporosis medication, bilaterality of operation site, degree of obesity, degree of knee function and osteoporosis diagnosis at operation in female patients above 65 years old, who received TKR due to severe knee osteoarthritis,Method: 52 patients who checked 1 year follow-up BMD were enrolled. Patients were checked the spine and hip BMD at pre-operat...

Introduction: The authors experienced a ipsilateral femoral stress fracture after total knee arthroplasty (TKR). Decreased bone mineral density (BMD) after TKR have been proposed as cause. However, reports regarding changes of BMD in the proximal hip after TKR have been rare. Therefore, first, we studied the question of whether TKR can effect change of proximal hip BMD? Second, if so, does TKR have different effects on BMD of the operative and non-operative sides?<p class=...
