Hi Dolphi:  Welcome to the community and thanks for your question.  I'm sorry you aren't seeing the results you expected with Fosamax, but the fact that you haven't gotten worse is considered and improvement, in most people.

Bone spurs are caused from osteoarthritis and age.  I've had this problem for years, and have never heard any Dr. associate it with osteoporosis.  To better explain bone spurs, how they develop, and their cause read the Mayo Clinics explanation on it.  I suggest reading through the entire article on it from start to finish so you can understand how this happens from various other disorders besides osteoarthritis.  There are many other spinal disorders that cause this that aren't related to osteoporosis, like DDD, spinal stenosis, spondylolisthesis etc, all of which is explained in the Mayo Clinic article.

Recently another member asked if Fosamax, Actonel, and Boniva could cause bone spurs, and the answer was no.  Read my answer to "airy" that explains how these drugs can help to slow or prevent bone spurs, according to the article/clinical study I mentioned in airy's post.

I hope your t-scores improve, but you might want to discuss a drug holiday with your Dr. to see if this is something that might help.  Fosamax stays in your system a long time so stopping it wouldn't have a dramatic affect if you took a couple of years off.  Here's an article, from our Expert Dr Gonter, on this as well that explains why a patient and Dr *might* consider a drug holiday.  It's important to know what you fracture risk is before you consider this, so ask your Dr. to check this possibility out.  Patients who are at high risk for fractures may not want to take a drug break, so find out if this applies to you by talking to your Dr.

Good luck and I hope you can find a treatment for the spurs, and also a beneficial plan on what to do next with the Fosamax.  If you have any other quesitons please post again, we're here to help whenever we can!
