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...

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...

Nutrition is a major modifiable factor that affects bone health. Dietary potassium may act as an alkaline source by neutralizing the acid load and reducing calcium loss from bone.We aimed to evaluate the association between dietary potassium intake and bone mineral density (BMD) in the Korean population. We analyzed data from the Korean National Health and Nutrition Examination Survey (KNHANES) A total of 3135 men aged >50 years and 4052 postmenopaus...

The present study figured out the relationship between social network and osteoporosis among elderly women. Social network could be beneficial to one’s health since it works as social capital providing several supports. On the other hand, social network can also be a source of social burden aggravating one’s health. To examine the seemingly contradicting associations, Korean Urban Rural Elderly Study (KURE) data was analyzed. There were 1938 older women aged over 65,...

Background: Denosumab (DMAB) is used in adults for the treatment of osteoporosis, giant cell tumour of bone, and cancer metastases. There are little data on paediatric use with clinical decision making reliant on adult data and clinical experience.Presenting problem: We have treated 33 children with DMAB: Perthes disease (n=9), avascular necrosis (n=17), osteoporosis (n=1), aneurysmal bone cyst (n=4) and giant cell tum...

Objectives: Adolescent idiopathic scoliosis (AIS) was associated with low bone mass which, apart from being an important health issue that could persist into adulthood, was also a significant prognostic factor for curve progression in AIS. We have performed a randomized controlled trial on whole-body vibration (WBV) and reported its effect on increasing femoral neck areal bone mineral density (aBMD) mainly at the dominant leg. The objective of this study was to evaluate the ro...

Objectives: Multiple studies have documented the presence of systemic osteopenia in adolescent idiopathic scoliosis and in simulated animal models. Osteopenia was also found to be associated with severe curves and as one of the prognostic factor in predicting curve progression in AIS. The objective of this study was to compare the bone quality and its association with osteopenia between AIS and normal controls.Methods: AIS (n=234) and non-AIS gi...

Objectives: AIS is associated with both low bone mass and elevated serum bone alkaline phosphatase. The greater the latitude of the geographical region, the higher is the prevalence of AIS. These specific features were compatible with the presence of either Vit-D insufficiency or abnormal physiology with Vit-D. It is important to evaluate these potentially treatable conditions regarding their roles in the etiopathogenesis of AIS. The objectives of this case-control study were ...

Introduction: Adolescent idiopathic scoliosis (AIS) is associated with osteopenia, which was found to be a significant prognostic factor for curve progression. However, in-depth quantitative assessment of bone quality was previously hampered by invasive nature of the investigations. The recently available high-resolution pQCT (HR-pQCT) allows a three-dimensional assessment of the bone quality in-vivo. This study aimed to evaluate and compare the bone quality in AIS gi...

Mesenchymal cells alter and retain their phenotype during skeletal development through activation or suppression of signaling pathways. For example, we have shown that Wnt3a only stimulates osteoblast differentiation in cells with intrinsic osteogenic potential (e.g., MC3T3-E1 pre-osteoblasts) and not in fat cell precursors or fibroblasts (respectively, 3T3-L1 pre-adipocytes or NIH3T3 fibroblasts). Wnt3a promotes osteogenesis in part by stimulating autocrine production of the ...
