Hey there!
I am 49 and had a first HR in 1988. All cemented, vacuum packed. In 2000, I had the acetabular cup revised, but they did not touch the femur component. Last year I started having thigh pain, when sitting on the floor, having kids on my lap, moving certain ways etc. Nothing showed up on X-rays for awhile. In January of this year I went in for a check-up and the x-rays showed that the titanium rod had broken in two and separated. The bottom portion of the rod was still tightly cemented but the top had gotten loose. I had a THR a few weeks after that (as soon as they could schedule it to lessen chances of a bone break). They cut the femur to remove all of the old cement and metal pieces. Everything was replaced, and I have lots of screws and wires to hold everything together.
The surgery was long (~ 6 hours), but turned out well. I had a great surgeon, a young guy (in his thirties) that I was referred to, by a well respected established older surgeon (not too old - in his mid-late fifties). While trying to figure out my thigh pain problem I tried making appointments with a few different surgeons, and the first established older guy I was referred to refused to see patients needing revisions of work he did not initiate. He referred me to someone younger who totally misdiagnosed the problem. I went to another surgeon for a second opinion, and he was the guy who referred me to the surgeon who finally did the revision. Apparently the surgery is a lot of work - for the younger guys. My surgeon seemed to specialize in revisions and I had the surgery done at a University medical center. I am glad I had the second opinion. I went back to work in six weeks, and everything is fine so far. No pain. I hope this one lasts for awhile! I would be happy to answer any questions. Good luck with your THR and let us know how it goes!
All the best!
Linda
