Osteoporosis is defined by the World Health Organization as a disease “characterized by low bone mass and micro-architectural deterioration of bone tissue, leading to bone fragility and a consequent increase in risk of fracture.” Osteoporosis is a significant, worldwide public health problem that is becoming increasingly common. It is estimated that globally, 1 of every 2 women and 1 of every 4 men older than 50 years will have an osteoporosis-related fracture. In the United States, 1.5 million fractures related to osteoporosis occur annually, with the estimated cost of caring for these patients approaching $18 billion. This number is expected to triple by the year 2040. In older patients, a broken hip can increase mortality fourfold. Those with hip fractures have a 20% risk of entering a nursing home within a year of their fracture, and it is estimated that almost 50% of women with hip fractures do not fully regain previous function. Many patients with hip fractures experience a decline in function, along with increased feelings of isolation, depression, and fear of falling. In an individual with osteoporosis, the potential for falling becomes even more important.
