Hip, Osteoporosis: New Paradigm.

Osteoporosis is the most common metabolic bone disease. Recently, the paradigm for diagnosis and treatment of osteoporosis has undergone changes due to new findings on this disease. With the arrival of densitometers that could measure BMD we started using medications that block further degradation of density and repair the densitometric results. More recent findings, however, suggest that the BMD value influences the predicted success of future fracture prevention in less than 50%. The remainder is attributed to bone quality. There are a number of risk factors for osteoporotic fractures, some of greater and some of lesser significance. A small external force is necessary to cause an osteoporotic fracture; otherwise, the osteoporotic bone still does not break. The dominant factor in a fracture is therefore the fall of the elderly patient. Falls are preventable, although most are benign and injury free. Only in the recent decade have we started paying attention to the fall phenomenon, which does not only involve accidents, but is also a consequence of the normal aging process. Incidence of falls and hip fractures in residential elderly patients can be reduced with a multifactorial interdisciplinary prevention program (MIPP):• Staff training • Adaptation of environment • Gait and mobility exercise • Technical accessories • Revision of pharmacotherapy (psychotropics) • Hip protectors • Post-fall problem-solving conferences. Mobility exercise is useful in elderly groups; however, the maintenance of mobility is not linked to a reduction of fall risk. Hip protectors are protective pads designed to cover the greater trochanter and attenuate or disperse the force of fall sufficiently to prevent a hip fracture. A number of cost-benefit studies on residential elderly patients between 2004 and 2006 proved the efficacy of MIPP and hip protectors, and some studies did so also on those patients living independently. Unfortunately, as much as 75% of women and 90% ofmen at high risk in nursing homes are not investigated, and 75% of those affected are not treated.
