Background: There is significant inter and intraobserver variability in diagnosing vertebral fractures in children. We aimed to evaluate the diagnostic accuracy of morphometric vertebral fracture analysis (MXA) using a 33-point software programme designed for adults, on dual-energy x-ray absorptiometry (DXA) images of children.Methods: Lateral spine DXA images of 420 children aged between 5 and 18 years were retrospectively reviewed. Vertebral fracture a...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in men of various ages.Materials and methods: 300 men aged 40–87 years (mean age – 60.5±0.6 years; mean height – 1.61±0.003 m; mean weight – 84.1±0.9 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=52), 50–59 years (n=90), ...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in women of various ages.Materials and methods: 494 women aged 41–89 years (mean age, 63.6±0.4 years; mean height, 1.61±0.003 m; and mean weight, 74.0±0.6 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=35), 50–59 years (n=130), 60–6...

The aim of the study was to evaluate the role of vitamin D and exercises in correction of age-related skeletal muscle changes in postmenopausal women.Materials and methods: 38 postmenopausal women aged 53–82 years (mean age – 67.00±7.08 yrs) were examined. The women were divided into the following groups: A – control group (n=10), B – women who took an individually-targeted vitamin D therapy (n=11), C – wom...

Arterial calcification is now considered as an actively regulated process resembling osteogenesis orchestrated by a number of systemic or constitutively expressed mediators. Genetic studies of rare inherited syndromes have identified key regulators of arterial calcification. Based on the pathogenic principles causing the diseases these can be classified into three groups:i) Disorders of an increased extracellular inorganic phosphate/inorganic pyrophospha...

Bisphosphonates are the mainstay of medical therapy in the fracturing child with osteoporosis. The majority of the data in children pertains to i.v. pamidronate use in children and adolescents with osteogenesis imperfecta (OI), where pamidronate has been associated with improvements in bone mineral density, cortical thickness, vertebral shape, pain, mobility and height.1 Side-effects of pamidronate including acute phase response to the initial dose and retardation o...

Low bone mass is common in thalassemia (Thal) and sickle cell disease (SCD). Bone pain is also reported, though its relationship to low bone mass has not been explored. The aims of this study were to determine the prevalence of vertebral height abnormalities (VHA) and evaluate the relationship between VHA, low bone mass and patient assessed pain in Thal and SCD. Data were collected from the Thalassemia Clinical Research Network Pain Survey study and CHRCO Clinical Bone Density...

Areal bone mineral density (aBMD) of the PA spine and proximal femur remained the gold standard for WHO classification of osteoporosis, fracture prediction and patient monitoring. Unfortunately, with age it is not infrequent to observe the presence of degenerative disease such as spinal osteoarthritis which would have a positive artifactual impact on aBMD which could lead to an erroneous interpretation. In a previous study it has been demonstrated that apparently such artifact...

Background: Rickets is a disorder of the growing child arising from impaired mineralisation of the growth plate and osteoid. The most common cause of NR in the UK is thought to be secondary to vitamin D deficiency [VDD; serum 25-hydroxyvitamin D (25OHD) <25 nmol/l], although in some African & South Asian countries dietary calcium deficiency (DCaD) by itself, or together with VDD is an important cause of NR (Ann Trop Paediatr. 2006;26:1–16). Currently, the data on ...

Introduction: Fracture healing is impaired in aged and osteoporotic patients. Because bone formation is tightly regulated by the mechanical conditions in the fracture gap and because suitable mechanical stimuli improve fracture healing (Claes et al. 1998), we investigated whether low-magnitude high-frequency vibration (LMHFV; Rubin et al. 2004) is able to improve delayed fracture healing induced by age and ovariectomy in mice.Sudy desig...
