The authors, all physicians involved in clinical research on bone and pract
icing clinicians, propose practical guidelines for identifying persons with
osteoporosis or those at high risk of developing the disease and for manag
ing patients who may benefit from therapy. These guidelines are based on an
analysis of peer-reviewed articles published before November 1998. A flowc
hart of women who might benefit from treatment is provided, including clini
cal presentation (recent fracture of the spine, hip, or other bone or no fr
acture; risk factors for osteoporosis); relevant investigations (bone miner
al density measurement and laboratory tests required for the differential d
iagnosis); and therapeutic management (general measures such as calcium and
vitamin D supplementation and specific pharmacologic interventions such as
estrogen, bisphosphonates, intranasal calcitonin, raloxifene, fluoride sal
ts, and other compounds that have been assessed in randomized clinical tria
ls). The strongest evidence for antifracture efficacy (reduction of vertebr
al and nonvertebral fracture risk) was observed with alendronate.
