The challenges of peripheral bone density testing: which patients need additional central density skeletal measurements?
Lower cost, portable, peripheral bone mass measurement devices are being increasingly utilized for widespread bone mass testing. These devices are being placed in traditional medical settings as well as nontraditional settings, such as pharmacies and grocery stores. Increased bone mass testing is appropriate at menopause in women who are undecided whether to begin systemic estrogen replacement. Women may decide to begin estrogen replacement if they are aware they have low bone mass and understand that bone mass will predictably decline after the menopause (1). With the approval of alendronate and raloxifene for the prevention of osteoporosis, even women who cannot or will not utilize estrogen replacement may be offered preventive interventions if they are identified as having low bone mass. More accessible bone mass measurements and more approved pharmacologic interventions will shift the focus of osteoporosis management to strategies that emphasize the reduction of lifetime fracture risk as well as current fracture risk. It will also be an impetus to focus on earlier identification and intervention (2-4).
