Results: Body height was normal for chronological age (p=0.96). Broadband ultrasound attenuation (BUA), either age-related of height-adjusted, was normal (p=0.18 and 0.26, respectively). Velocity of sound (VOS), either age-related of height-adjusted, was low (p=0.002 and p=0.003, respectively). We found no correlations between Fx and BUA or Fx and VOS (either age-related or height-adjusted) (r =0.01 and 0.02; r =0.32 and 0.26 ). Neither were there any correlations between U-Ca and Fx (r =0.28), or U-Ca and BUA (r =0.21 and 0.32) or VOS (r =0.40 and 0.42), respectively. Conclusions: Contrary to previous observations where dual-energy X-ray absorptiometry (DXA) was used for BMD evaluation, we found only mild decrease in one QUS parameter with no relationship to fracture rate or calciuria. Children with IH have normal values of BUA and low VOS, not related to calciuria and Fx. QUS is not a surrogate to DXA and its role needs to be further clarified.
