J. Nijs et al., Ultrasonographic, axial, and peripheral measurements in female patients with benign hypermobility syndrome, CALCIF TIS, 67(1), 2000, pp. 37-40
Twenty-five female Caucasians, aged 19-57 years, with the hypermobility syn
drome had bone density measurements using established noninvasive technique
s such as dual X-ray absorptiometry (DXA), single photon absorptiometry (SP
A), heel ultrasound (US), and peripheral computed tomography (pQCT) acquisi
tions of the radius. As a group, comparisons of the different bone indices
with the corresponding age-matched reference population resulted in normal
z-scores for the arial densities, however, values for the volumetric total
and cortical bone at the radius measured by pQCT were significantly lower t
han expected (P < 0.0001). Spinal and femoral bone density results were sig
nificant after correction for body mass index (BMI). This cross-sectional s
tudy shows that the benign hypermobility syndrome patients have lowered t-s
cores for data reflecting bone structure and bone strength as measured with
US and the tomographic technique.
