Objective: Due to the increase in the elderly population, osteoporosis and related fractures are increasing and causes serious social problems such as lower quality of life of seniors and economic loss. This study is aimed towards the general population in rural areas for prevalence and related risk factors of osteoporotic fracture.Materials and methods: The research comes from the Korean Rural Genomic Cohort study consisting of 10 111 people, 4090 men a...

Study Design: Retrospective study.Purpose: To estimate the usefulness of bone scan and magnetic resonance imaging (MRI) for the diagnosis of new fracture in osteoporotic vertebral fractures.Overview of Literature: The diagnosis of new fracture in osteoporotic vertebral fractures requires simple X-ray and supplementary studies.Methods: We analyzed 87 vertebrae in 44 patients, who diagnosed with osteoporotic ve...

Background: Asian-specific prediction model for estimating the individual risk of osteoporotic fracture was rare. We aimed to develop a Korean fracture risk prediction model using clinical risk factors and assess external validity of the final model.Methods: A total of 718,306 Korean men and women aged 50–90 were followed for 7 years in national system based cohort study. Fifty percent were randomly assigned to the development dataset and 50% to the...

A 20-year-old male presented following a fall down. He was diagnosed with a C5–C7 burst fracture and underwent a cervical fixation surgery. He was transferred to inpatient rehabilitation with C6 ASIA A tetraplegia.70 days after the operation, he began to have intermittent mild fever with a temperature of 37.4 oC. On postoperative day 72, left thigh was noted to be edematous. The circumferential difference between the lower extremities mea...

Background and objectives: Fracture in rheumatoid arthritis (RA) patient is more frequent than general population. One of the important reasons is use of glucocorticoid (GC) for treatment of RA. In this study, we aimed to identify the effect of GC on fracture of different site.Methods: Among RA patients ≧19 years, we established a retrospective cohort using Korean national healthcare claims database from Jan 2010 to Dec 2010, and then followed up unti...

The aim of this study was to investigate BMD of affected femur in patients with hemiplegic stroke.Medical records of 153 patients with stroke who admitted a rehabilitation clinic from January 2011 to March 2013 were retrospectively reviewed. We excluded the patients with non-hemiplegia, diseases which can affect the BMD such as diabetes mellitus, thyroid disease and anti-epileptic drugs. We also excluded the patients who did not check both femur BMD. Tot...

Periodontitis is an inflammatory disease that affects connective tissue attachments and the supporting bone that surrounds the teeth. Periodontal ligament fibroblasts induce the overexpression of matrix metalloproteinase (MMP), which is involved in inflammatory progression in periodontitis. Osteoclasts are responsible for skeletal modeling and remodeling but may also destroy bone in several bone diseases, including osteoporosis and periodontitis. This study examined the anti-d...

This study examined the anti-osteoclastogenic effect of n-butanol extracts of Panax notoginseng on the receptor activator of NF-kB ligand (RANKL) induced RAW264.7 cells. Panax notoginseng is commonly used to treat chronic liver disease. Notoginseng has many beneficial effects, such as the suppression of liver fibrosis and anti-cancer activities. Notoginseng contains several biologically active components, such as ginsenosides Rb1, Rg1...

Objective: Bone is one of endocrine organ and osteocytes secretes FGF23, Sclerostin and DKK1. FGF23 inhibits renal phosphate reabsorption and suppresses 1-α hydroxylase activity. Calcitriol stimulates FGF23 synthesis in bone. We aimed to determine the effect of single bolus injection of vitamin D on serum FGF23, DKK1 and Sclerostin concentrations in vitamin D-deficient subjects.Design and methods: The study group was composed of placebo group with s...

Background: Hypophosphatasia (HPP) is a rare skeletal disease characterized by defective bone and teeth mineralization and the deficiency of tissue non-specific alkaline phosphatase activity. This disorder is caused by mutations in the ALPL gene, which encodes TNAP. The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization (perinatal form) to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pa...
