Lateral thoracolumbar spine radiographs were performed for VF assessment. Genant classification was applied for VF severity grading (mild, moderate and severe). Body composition analysis using dual-energy X-ray absorptiometry was performed. Serum calcium, phosphate, intact parathyroid hormone and 25-hydroxyvitamin D concentrations were determined.RESULTSThere were 25 children and adolescents with DMD enrolled. Median (IQR) age was 12.9 (9.6, 19.3) years. Nine patients (36%) had VFs with a total of 31 sites of VFs (mild, N=10; moderate, N=3 and severe, N=18).
