OBJECTIVES To assess the effect of conditioning exercise on bone parameters at multiple sites in the radius and tibia of young Thoroughbred horses. METHODS The left and right radius and tibia were obtained from twelve horses, six of which had received conditioning exercise and six which formed the control group. Each bone was scanned at 5% intervals along its entire length using pQCT. RESUL...

 Abstract  Background: Resection of the distal end of the radius is indicated in the treatment  of locally aggressive primary benign and malignant bone tumors. The aim of this study  was to evaluate the technique of osteoarticular allograft reconstruction of the distal radius after wide excision of a giant-cell tumor.  Methods: We analyzed 15 patients retrospectively who had reconstruction of t...

OBJECTIVE It is important to estimate the bone metabolism in patients with renal osteodystrophy. The methods of estimation must be noninvasive, accurate, and able to measure repeatedly. METHODS The regions of interest on bone scintigraphy were drawn over the radius in 22 hemodialysis patients (10 males, 12 females). The bone/soft tissue ratio (B/ST ratio) was calculated for all patients. The ...

background: although giant cell tumor (gct) is considered to be a primary benign bone tumor, its aggressive behavior makes its diagnosis and treatment, difficult and challenging. this is especially true in distal radius where gct appears to be more aggressive and difficult to control locally. we report our clinical outcome of en-block resection and reconstruction with non-vascularized fibular a...

PURPOSE To investigate by histomorphometry the distraction osteogenesis by Ilizarov technique in dog radius with the use of autologous stem cells in regenerated bone. METHODS Ten dogs (20 radiuses) underwent the osteotomy of 20% of extension of their radiuses, and osteogenic distraction using the Ilizarov technique after this procedure at rate of 1mm per day divided into 0.5mm every 12 hours....

BACKGROUND Measurement of bone mineral density by dual x-ray absorptiometry combined with clinical risk factors is currently the gold standard in diagnosing osteoporosis. Advanced imaging has shown that older patients with fragility fractures have poor bone microarchitecture, often independent of low bone mineral density. We hypothesized that premenopausal women with a fracture of the distal en...

A compact MRI system for trabecular bone (TB) microstructure measurements of the distal radius was developed using a 1.0 T permanent magnet and a compact MRI console. TB microstructure of the distal radius was clearly visualized using a three-dimensional (3D) driven equilibrium spin-echo (DESE) sequence in 23 min. The image obtained had a sufficient spatial resolution (150 microm x 150 microm x...

Teriparatide significantly increases bone mineral density (BMD) of the lumbar vertebrae and femur and has a strong effect in reducing the risk of bone fractures. However, few detailed investigations with dual-energy X-ray absorptiometry (DXA) of the effects of teriparatide on the radius have been reported; specifically, there are no reports of the use of once-weekly teriparatide. In this study,...

OBJECTIVES To define pQCT precision errors, least-significant-changes, and identify associated factors for bone outcomes at the radius and tibia in children. METHODS We obtained duplicate radius and tibia pQCT scans from 35 children (8-14yrs). We report root-mean-squared coefficient of variation (CV%RMS) and 95% limits-of-agreement to characterize repeatability across scan quality and least-s...

Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF) have beenwell demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. After an osteotomy of the midshaft radius...
