Bones are not inert. The two are closely linked. If breakdown exceeds formation, bone tissue is lost and bones become thin and brittle. Gradually and without discomfort, bone loss leads to a weakened skeleton incapable of supporting normal daily activities. Each year about 500,000 American women will fracture a vertebrae, the bones that make up the spine, and about 300,000 will fracture a hip.
Vertebral fractures lead to curvature of the spine, loss of height, and pain.
A severe hip fracture is painful and recovery may involve a long period of bed rest. Between 12 and 20 percent of those who suffer a hip fracture do not survive the 6 months after the fracture. At least half of those who do survive require help in performing daily living activities, and 15 to 25 percent will need to enter a long-term care facility. Older patients are rarely given the chance for full rehabilitation after a fall. However, with adequate time and care provided in rehabilitation, many people can regain their independence and return to their previous activities.
