Purpose: There is no agreed standardised method for assessing vertebral morphology. The algorithm-based qualitative technique appears to be promising in adults to rule out non-osteoporotic fractures and non-fracture deformities, however it has not been previously trialled in children. We aim to modify a technique for use with both dual energy X-ray absorptiometry and radiographs in children, and to evaluate its reliability and reproducibility.Methods: 50...

Purpose: Children have greater lifetime risks of radiation-induced complications compared to adults. In children with osteogenesis imperfecta conventional radiographs are obtained to assess spine morphometry, while DXA assesses bone density. In adults DXA is now used for both. We aim to establish whether iDXA can replace spine radiographs in the assessment of paediatric vertebral morphometry.Methods: An 18-month prospective recruitment of 200 consented c...

Purpose: We aimed to assess observer reliability and diagnostic accuracy in children, of a semi-automated 6-point technique developed for vertebral fracture diagnosis in adults, which records percentage loss of vertebral body height.Methods: Reading 137 spine radiographs of children and adolescents, diagnostic accuracy (sensitivity, specificity and 95% confidence interval) calculations of five observers’ for SpineAnalyzer were calculated. Comparison...

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...
