My hip deteriorated from ostopenia to severe osteoporosis- probably due to extended time on drugs like Prednisone. I ended up fracturing my hip (total break) by overstepping it while exercising with no fall.

The ortho surgeon noted that the porousness and poor condition of the bone posed challenges, but they were able to do a hip replacment. That was 2 years ago. He did a good job and I have not had any problems.

It was important to find a very experienced surgeon who was used to complex procedures.
