three times as many hip fractures as men. In a lifetime, men have an estimated 6% risk whereas postmenopausal women have an estimated 14% risk of having a hip fracture. These statistics provide insight over a lifespan, and conclude that women are twice as likely to have a hip fracture. The overwhelming majority of hip fractures occur in white individuals, while blacks and Hispanics have a lower rate of them. This may be due to their generally greater bone density and also because whites have longer overall lifespan and higher likelihood of reaching an advanced age where the risk of breaking a hip goes up. Deprivation is also a key factor: in England, it has been found that people in the poorest parts of the country are more likely to fracture a hip and less likely to recover well than those in the least deprived areas. Age related Age is the most dominant factor in hip fracture injuries, with most cases occurring in people over 75. The increase of age is related to the increase of the incidence of hip fracture, which is the most frequent cause of hospitalization in centenarians, overcoming congestive heart failure and respiratory infection. Falls are the most common cause of hip fractures; around 30–60% of older adults fall each year. This increases the risk for hip fracture and leads to the increased risk of death in older individuals, the rate of one year mortality is seen from 12 to 37%. For those remaining patients, half of them need assistance and cannot live independently. Also, older adults sustain hip fractures because of osteoporosis, which is a degenerative disease due to age and decrease in bone mass. The average age for sustaining a hip fracture is 77 years old for women and 72 years old for men.
