Wright et al. applied NHANES 2005–2010 DXA data to 2010 US Census counts to estimate how many Americans aged 50+ meet WHO criteria for osteoporosis or low bone mass. The study used both femoral neck and lumbar spine BMD — the first nationally representative US estimate to include both sites. Projections through 2030 quantify the growing burden driven by demographic aging alone.
More than half your patients over age 50 have osteoporosis or low bone mass — and the majority are undiagnosed.
When you order a DXA, use both femoral neck and lumbar spine. Using femoral neck alone misses 54% of osteoporosis cases that the lumbar spine would catch, primarily because the spine's trabecular-rich architecture is more vulnerable to early bone loss. The NOF guidelines include both sites for exactly this reason: to identify patients at risk for vertebral fracture, which is the most common osteoporotic fracture and a known precursor to hip fracture.
Adding the total hip adds essentially nothing to your diagnostic yield. Skip it unless another indication exists.
For the boards and for practice: prevalence data from this paper means that any patient over 50 presenting with a fragility fracture or low-trauma injury should trigger a bone health evaluation, regardless of sex or race. Men are underscreened relative to their real burden (2 million with osteoporosis), and the 32% projected increase in affected individuals by 2030 means this problem is growing.
