Body segment lengths and arm span in healthy men and women and patients with vertebral fractures

Abstract

We studied 112 healthy men and 261 healthy women aged 18-92 years, and 34 men and 73 postmenopausal women with vertebral fractures aged 45-90 years to determine (i) whether patients with vertebral fractures have shorter stature before fracture, and (ii) whether the difference between arm span and standing or sitting height can be used to identify patients with fractures. Arm span was measured by using a calibrated extended ruler. Standing height, sitting height and leg length were measured by using a Holtain stadiometer. The results were expressed in absolute term and standard deviation (SD) or Z-scores (mean ± SEM). Advancing age was associated with decreased sitting height (r = -0.37 to -0..
