Osteoporosis is a condition of aging, whereby the density of bone decreases due to increased bone resorption from hormonal and nutritional factors, which increases the risk of bone fractures. Experts have determined that testing bone mineral density (BMD) is not as sensitive when determining bone strength in osteroporotic patients. BMD measurements are taken by dual-energy x-ray absorptiometry (DEXA) scanning of the vertebrae (spine), wrist and femur (leg bone) and can give an indication as to the threat of fractures and diagnosing osteoporosis in untreated patients. Patients on treatment for osteoporosis, e.g bisphosphonates, require a multifactorial bone quality testing method that incorporates DEXA scanning and other measurements to determine bone strength.
