Own the Bone

Own the Bone

Billings Clinic is proud to host Own the Bone, a national quality improvement program designed by the American Orthopedic Association to improve patient outcomes after a fragility fracture. In plainer language, we’re working to keep more broken bones from happening.

I had a broken bone, now what?

If you’ve been told you have a “fragility fracture” or “osteoporosis” or “osteopenia,” you may be wondering what this means. These are all terms that come up when bones have become weaker than they should be, which leads to breaks even with minor falls and injuries. The good news is that there are steps we can take to help you improve the health of your bones and reduce the chances of another break. Welcome to Own the Bone.

So what do I do?

You will meet with a Nurse Practitioner in the Own the Bone program. Usually this can be scheduled the same day you meet with your orthopedic surgeon. We will talk about some blood tests and bone density testing – these tests may be done before your appointment or we might schedule a follow up visit after they’re done. The tests will help us understand what’s going on with your bones and the best way to strengthen them. We may even discuss starting some medications that help with osteoporosis. Then the Nurse Practitioner will teach you some strategies to improve the health of your bones, so you can Own the Bone.

What comes next?

Depending on your test results and what’s right for you, you might come back to talk to the Nurse Practitioner about medication OR you can take the information back to your primary care provider and talk about it with them.

Anything else?

There is a national study collecting data about this program. You may be asked to sign a consent form at your first visit that allows us to enter some information about your fracture into this study. The national study does not collect anything specific about you – all the information is anonymous. You can still visit with our Nurse Practitioner if you choose not to participate in the study.
