Preventing Falls, Fractures and Broken Bones in Elders

Falls, fractures and hip replacements are common problems in elderly people, due to bone loss, bone fragility and osteoporosis. Did You Know?

* More than 90 percent of hip fractures are associated with osteoporosis.
* Nine out of 10 hip fractures in older Americans are the result of a fall.
* Elderly individuals who have a hip fracture are 5 to 20 percent more likely to die in the first year following that injury than others in this age group.
* For those living independently before a hip fracture, 15 to 25 percent will still be in long-term care institutions a year after their fracture.

Falls are serious at any age, and breaking a bone after a fall becomes more likely as a person ages. Many of us know someone who has fallen and broken a bone. While healing, the fracture limits the person’s activities and sometimes requires surgery.

Often, the person wears a heavy cast to support the broken bone and needs physical therapy to resume normal activities. People are often unaware of the frequent link between a broken bone and osteoporosis. It is known as a silent disease because it progresses without symptoms, osteoporosis involves the gradual loss of bone tissue or bone density and results in bones so fragile they break under the slightest strain. Consequently, falls are especially dangerous for people who are unaware that they have low bone density. If the patient and the doctor fail to connect the broken bone to osteoporosis, the chance to make a diagnosis with a bone density test and begin a prevention or treatment program is lost. Bone loss continues, and other bones may break.

Even though bones do not break after every fall, the person who has fallen and broken a bone nearly always becomes fearful of falling again. As a result, she or he may limit activities for the sake of “safety.” Among Americans age 65 and older, fall-related injuries are the leading cause of accidental death.
