As the world population of older adults—in particular those over age 85—increases, the incidence of fragility fractures will also increase. It is predicted that the worldwide incidence of hip fractures will grow to 6.3 million yearly by 2050. Fractures result in significant financial and personal costs. Older adults who sustain fractures are at risk for functional decline and mortality, both as a function of fractures and their complications and of the frailty of the patients who sustain fractures. Identifying individuals at high risk provides an opportunity for both primary and secondary prevention.

Key points
• The incidence of fragility fractures is increasing rapidly, although age-adjusted rates seem to be declining.
• Poor outcomes are related both to fractures and their comorbidities and to the frailty of the patients who sustain fractures.
• Identifying individuals who are at highest risk, using a prediction tool such as the FRAX, can allow for targeted primary prevention.
• A person who sustains one fracture is at 50% to 100% higher risk of having another one; fractures, therefore, provide important opportunities for secondary prevention.
• Hip fractures cost Medicare more than $12 billion per year.
Introduction
The United States and the rest of the world are experiencing a silver tsunami. Since 2011, 10,000 American baby boomers are turning 65 daily. The older adult population in the United States is predicted to more than double, from 35 million individuals in 2000 to 72 million in 2030, and will account for approximately 20% of the population.2
The oldest old, those over age 85, are the fastest growing segment of the population. The baby boomers will start turning 85 in 2031, and it is predicted that the population over age 85 will increase 3-fold, from 5.5 million in 2010 to 19 million in 2050.2 Although there is evidence that people are living healthier lives for longer,3 and that age-adjusted fracture risk is decreasing, 4,5 these individuals remain at highest risk of sustaining fragility fractures.6
Fragility fracture is defined as a fracture that results from a low trauma event, such as falling from a standing height or less.1
As the incidence of fragility fractures rises, it becomes more important to optimize their prevention and treatment.
Prevalence/Incidence
For each decade after age 50, the risk of hip fracture doubles.7 At age 50, an American white woman has a 17% lifetime risk of sustaining a hip fracture, 8,9 and a woman who lives to age 90 has a 1 in 3 chance of sustaining a hip fracture.10 The increased risk with age combined with a rapidly expanding older adult population translates to a projected increase in worldwide hip fracture incidence, from 1.7 million in 1990 to 6.3 million in 2050.11
The incidence of hip fractures has been demonstrated to be increasing in many countries around the world, including Asia, North America, and Europe.12 The risk of a hip fracture varies significantly based on gender, race, and ethnicity. The graph in Fig. 1 shows how the expected number of hip fractures is changing over time in 8 regions around the world.11
Fig. 1 The expected number of hip fractures over time in 8 regions around the world. (Modified from Cooper C, Campion G, Melton LJ 3rd. Hip fractures in the elderly: a world-wide projection. Osteoporos Int 1992;2(6):285–9; with permission.)
When reflecting on the full burden of osteoporotic or fragility fractures, it is essential to also consider the morbidity associated with fractures other than hip fractures. The lifetime incidence of any osteoporotic fracture is estimated to be 40% to 50% in women and 13% to 22% in men.9 At age 50, an American white woman has a 15% chance of sustaining a Colles fracture and a 32% chance of sustaining a vertebral fracture.10
Outcomes
A hip fracture can be a life-changing, or life-ending, event (Box 1). The surgery itself carries a 4% mortality overall,13 and within a year, approximately 20% die. 14–17 Patients with hip fracture experience a 5- to 8-fold increase in all-cause mortality in the first 3 months after the fracture, with men experiencing particularly high risk.18 This excess risk declines over time but never resolves completely, likely reflective of the frail population who sustain the fractures in the first place. The lifetime risk of death in women from hip fractures has been noted to be comparable to that associated with breast cancer.19
Box 1 Outcomes of hip fractures
• Increased mortality
• Loss of function
• Reduced mobility
• Need for increased health care services
• Risk of nursing home admission
• Depression
• Cognitive impairment
• Increased risk of future fracture
• High cost
In addition to the risk of mortality, hip fractures can lead to loss of function and mobility, which in turn can result in a loss of independence. A year after surgery, more than half of those who were previously independent are still unable to climb 5 stairs, get in and out of a shower, get on or off a toilet, walk a block, or rise from an armless chair without either equipment or human assistance.20 Only 60% have recovered to their previous level of walking.21 One-third of previously community-dwelling individuals require long-term nursing home care.22 Morbidity after a hip fracture is not just physical; there is a high incidence of depression that can occur early after a hip fracture,23 and both temporary and permanent cognitive impairment are also common.24
Hip fractures are costly events in the United States. The incremental direct cost to Medicare of a hip fracture has been estimated to be more than $25,000 during the period 1999–2006.25 Although hip fractures account for only 14% of fractures, they account for 72% of costs, amounting to more than $12 billion in 2005.26 These costs are driven by acute inpatient and postacute institutional care needs.27
Although fractures of the hip may be the most feared, other fragility fractures have important prognostic and functional significance. In addition to the acute and chronic pain associated with vertebral fractures, these fractures can lead to multiple outcomes that limit function. Kyphosis that occurs from vertebral collapse can lead to neck pain, reduced pulmonary function,28 costo-iliac impingement syndrome,29 and fear of falling.30 The mortality after a vertebral fracture has been noted to be similar to that after a hip fracture.31
An individual who sustains one fracture is 50% to 100% more likely to sustain a fracture of another type.8 Vertebral deformities from a fracture are associated with a 2.8-fold increased risk of hip fracture and 5 times the risk of another vertebral fracture in 3 years.30 The epidemiology of fractures at different sites varies, however; the median age for sustaining a Colles fracture is 66 versus 79 for the median age of first hip fracture.10 Identification of the fracture and understanding of future risk thereby provide an important opportunity for secondary prevention.
Clinical correlation
As primary prevention efforts improve, the onset of first fracture is delayed. The age of hip fracture patients has increased over time,4 and, as a concomitant phenomenon, patients have more comorbidities.4 Fragility fractures are, therefore, not only an outcome of frailty but also a marker of frailty.
Perioperative risk is increased in the face of comorbidities, with a higher burden of chronic conditions leading to an elevated risk of postoperative complications 32,33 and mortality. 32,34 The need to optimize comorbidities in the acute setting at the time of fracture, as well as the need to manage increasingly...
