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...

Background: In 2004, we reported a 48.1% prevalence of osteoporosis in an Ibansung cohort. The current prospective intervention study was undertaken in order to estimate the prevalence of osteoporosis from 2004 to 2015 and the increasing treatment rate of osteoporosis following osteoporosis screening tests with ultrasound bone densitometry and education in the same cohort.Methods: From November 1, 2014 to August 31, 2015, 960 adults ≥50 years of ag...

Introduction: Vertebral fracture has been recognized as a major health concern. Our purposes were to evaluate the trends in the incidence and mortality of vertebral fracture between 2008 and 2012 and predict the number of vertebral fracture that will occur in Korea up to 2025, using nationwide data from the National Health Insurance Service (NHIS).Method: A nationwide data set was evaluated to identify all new visits to medical institutes for vertebral f...

Introduction: The purposes of this study were to evaluate the trends in the incidence and mortality of hip fracture between 2008 and 2012, and predict the number of hip fractures in Korea up to 2025, using nationwide claims data.Methods: Nationwide claims data managed by the National Health Insurance Service (NHIS) was used to identify patients with hip fracture. All new visits or admissions to medical institutes for hip fracture aged 50 years or more be...

Objective: The postmenopausal women and elderly men have a big burden for osteoporosis related vertebral fracture and the frequency of clinically unrecognized vertebral fracture is known to be increasing. Vertebral Fracture Assessment (VFA) using DXA is a convenient and safe method to patients together with bone density test and is reported to be proper as a screening method to prevent additional vertebral fracture as diagnosing the vertebral fracture with unrecognized symptom...

Background: The prevalent vertebral fracture (VF) is a risk factor for future VF, which can be decreased with drug therapy. However, most VFs are not recognized clinically. VFA by DXA and spine X-ray can be performed to detect these prevalent VFs.Objectives: This study aimed to estimate the costs, effectiveness, and radiation exposure of VF diagnostic strategies.Methods: Markov model over a 10-year period was used to calculate the ...

Evidence indicates that dipeptidyl-peptidase 4 (DPP4) plays a distinct role in bone metabolism. However, there has been no report on the association, if any, between circulating DPP4 levels and osteoporosis-related phenotypes. This study aimed to determine if DPP4 predicts osteoporotic fracture (OF) risk in postmenopausal women. This case–control study was conducted in multiple centers in Korea. We enrolled 178 cases with OF and 178 age- and body mass index-matched contro...

Objectives: Vertebral fracture (VF) is a hallmark of osteoporosis, and it increases morbidity, mortality and large amount of medical cost. In this study, we aimed to describe the treatment pattern and estimate the cost of VF among elderly patients in Korea.Methods: Using Korean national healthcare claims database, we analyzed a 2% sample of patients aged ≧ 50 years between years of 2008 and 2012. New VF was identified on the basis of selected ICD-10 c...

Lipid raft microdomains have important role in cellular signaling. Caveolae are a specialized type of lipid rafts that are stabilized by oligomers of caveolin protein. Here we showed that caveolin-1 (Cav-1) is a critical membrane structural protein of osteoclast. In microarray analysis, we found that caveolin-1 was significantly up-regulated by RANKL. Knock-down of Cav-1 in bone marrow derived-macrophage reduced osteoclastogenesis. Consistent with the in vitro results...

Introduction: Percutaneous vertebroplasty is a well known surgical method to put the bone cement at osteoporotic vertebrae. There was a few report concerning about bone cement related complication such as dislodgment of injected cement. There are some contradictory study for long term reaction to bone cement in osteoporotic bone, especially injected cement features. This study is to assess the radiographic features of patients who underwent percutaneous vertebroplasty (PVP) in...
