Purpose: The purpose of this study was to scan femoral heads from cadaveric donors and investigate the microarchitecture within each femoral head comprehensively.Material and methods: Ten proximal femora was harvested from eight human cadaveric donors and these specimens were scanned using micro-computed tomography. Reconstructed batches of images were aligned along the main trabecular direction (MTD). The upper hemisphere of each femoral head was includ...

Purpose: Risk factors for intertrochanteric fracture (IF) severity were not studied thoroughly despite the high failure rate of osteosynthesis. The purpose of this study was to identify the risk factor for each fracture type using AO/OTA classification in elderly female patients who experienced IF.Materials and methods: This retrospective study identified 240 women over 50 years old with an incident IF in whom dual-energy x-ray absorptiometry (DEXA) was ...

Introduction: To compare serum vitamin D levels in elderly patients with or without osteoporotic spinal compression fractures (OSCF) and to evaluate a correlation between serum vitamin D level and several variables such as age, and bone mineral density (BMD), bone turnover markers.Methods: The medical records of 78 patients with OSCF (fracture group) and 84 age-matched control patients who were diagnosed osteoporosis without OSCF (control group) were rev...

Introduction: To analyze clinical assessment and efficacy of once-yearly i.v. zoledronic acid for osteoporosis.Materials and methods: The subjects were 322 osteoporotic patients who received more than single infusion of zoledronic acid in our hospital from October 2008 to March 2011. On clinical assessment, the adherence was evaluated by measuring the rate of reinfusion. Adverse events were recorded for safety assessment. For efficacy assessment, the bon...

Purpose: The purpose of the present study was to characterize the extent of sarcopenia among orthopaedic surgery patients.Methods: This retrospective cross-sectional study identified 222 patients immediately after or before an orthopaedic surgery including elective total hip and knee arthroplasty and hip fracture surgery at a single institution. 364 patients from an outpatient department who did not have an orthopaedic surgery were also examined as a con...

Aging is associated with a loss of systemic bone mass and an increased risk of especially the spine and hip. Therefore bone loss of teeth and ridge resorption can occur in the mouth. However, results of several studies investing association between systemic bone density and oral health have varied. In this study, we investigated the relationship between osteoporosis and dental caries with the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2008&#1...

Sacral insufficiency fracture is known as a common cause of lumbosacral pain developed without evident trauma in patients with osteoporotic spinal compression fracture. The purpose of study was to investigate the incidence and predisposing factors of sacral insufficiency fracture accompanied by osteoporotic spinal compression fracture.We carried out a retrospective study of 949 patients who were measured bone mineral densitometry (BMD) and showed osteopo...

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...
