Osteoporosis in senior citizens means lifelong treatment .If treatment is being diligently taken there is a benefit of 5yrs of life. Here is a study.

Clinical researchers have noted an extraordinary and unexpected benefit of osteoporosis treatment – that people taking bisphosphonates are not only surviving well, better than people  without osteoporosis, they appear to be gaining an extra 5 years of life

Out of a total cohort of around 2,000, a sub-group of 121 people were treated
with bisphosphonates for an average of 3 years. When compared with other
sub-groups taking other forms of treatment, such as Vitamin D (with or without
calcium) or hormone therapy, the longer life associated with bisphosphonate
treatment was marked and clear.

In a group of women with osteoporotic fractures aged older than 75
years, you would expect 50% to die over a period of 5 years. Among women in
that age group who took bisphosphonates, the death rate dropped to 10%.
Similarly, in a group of younger women, where you would expect 20% to 25% to
die over 5 years, there were no deaths. The data were consistent with about a 5
year survival advantage for people on bisphosphonates.”

We speculate that it may have something to do with the fact that bone acts as
a repository for toxic heavy metals such as lead and cadmium,” said Dr. Eisman.
“So when people get older, they lose bone. When this happens, these toxic
materials are released back into the body and may adversely affect health. By
preventing bone loss, bisphosphonates prevent some of this toxic metal release.
While we know that this is the case, we don’t yet have evidence that this
produces the survival benefit.”
