Background: Osteoporosis is a condition in the skeleton that is characterized by reduced bone density and an increased risk of fractures [1]. Back pain and osteoporosis with vertebral fractures are common conditions in elderly women that significantly affect their quality of life. Vertebral fractures are the most common type of osteoporotic fracture [2]. Vertebral fractures are underdiagnosed and are a major problem. It is estimated that only one third of vertebral fractures are clinically detected [3]. The lifetime risk for a Swedish postmenopausal woman to get a clinically detected vertebral fracture is approximately 15% [4].
