When former President Ronald Reagan fell and broke his hip at the age of 89 , he joined a group of more than 350,000 elderly Americans who fracture their hips each year. Suffering from advanced Alzheimer's disease, Reagan is in one of the highest-risk groups for this type of accident. The incidence of hip fractures not only increases after age 50 but doubles every five to six years as the risk of falling increases. Slipping and tumbling are not the only causes of hip fractures; weakened bones sometimes break spontaneously. But falling is the major cause, representing 90% of all hip fractures. 
These injuries are not to be taken lightly. According to the American Academy of Orthopedic Surgeons, only 25% of those who suffer hip fractures ever fully recover; as many as 20% will die within 12 months. Even when patients do recover, nearly half will need a cane or a walker to get around.
