Current treatment approaches to osteoporosis - 2013.

The clinical diagnosis of osteoporosis has evolved over the past 20 years to emphasize the relationship between compromised bone strength and fracture susceptibility. The goal of treatment of osteoporosis is fracture prevention. The aging of the American population will place additional burdens on our healthcare system among which will be the need to treat and prevent the estimated increase in fracture rates projected over the next 10 years. There is a significant number of currently available bone strengthening medications used in the treatment of osteoporosis, and this report highlights the effects of these drugs on bone mineral density values and on the relative rates of fragility fractures when these drugs are compared to placebo in clinical trials of subjects with osteoporosis. Identifying those individuals most in need of immediate treatment to prevent fractures remains a challenge despite the use of fracture risk assessment tools, which assess bone mineral density and clinical parameters in order to define an individual's risk of fracture over a finite period of time. Newer tools that may help better define bone strength (resistance to fracture) include high resolution MRI and finite element analysis of the MRI generated images, and this technology and our experience with it is briefly reviewed in this report. There are a number of new classes of drugs in development for the treatment of osteoporosis, and the clinician is likely to have additional antiresorptive and anabolic agents as treatment options for this condition over the next few years.
