Great thread!
I saw this mentioned by another patient on another thread and thought "that sounds like overkill!". I, myself, had pretty massive spurs which were partly responsible for some of my impingement issues. My surgeon didn't talk to me about this issue (I didn't know to ask). He did, however, put me on Celebrex (an NSAID) for a month after each surgery. I haven't seen him yet to ask, but I wonder if he does this to help not only with pain, but as a potential prophylaxis for HO (heterotopic ossification).
T-bone, I reviewed a quick list of PubMed studies. I saw one from 1997 from a European center comparing Indomethacin (NSAID) to radiation and found equivalent results. A second study from 2004 from a Greek center that suggested superiority of radiation. HOWEVER, this study included all patient undergoing "major hip procedure". This could include trauma, etc. The European study was specifically for cementless THA.
A final study I saw compared the cost-effectiveness of the two and is from 2008 at Rush Medical Center here in the good ole USA in Chicago. It suggested NSAIDs are cheaper, but may have higher complications, the most common being intestinal bleeding. They proposed that the "intangible" aspects of these complications would probably favor radiation, even though it was more expensive. Go figure the study was done by radiation doctors. . .
I will say anecdotally that Celebrex has a lower (not zero) complication of GI bleeding than indomethacin by far. This would make the results from the above study from Rush seem less clear.
Does it matter whether you use one NSAID or another?
Well, I found a study from Austria from 2003 that suggests probably not. They tested indomethacin vs meloxicam (another NSAID) and found no significant difference. I also saw a study that looked at ibuprofen and this seemed to help the problem also compared to placebo. I take the results I have seen to suggest any NSAID helps.
How often does this happen?
Well, the most recent study I could find is from 2007, but was Japanese, so may not apply to all of us (dietary, genetic issues, etc.). This showed HO to be a rare problem at around 5% for any HO and around 1% for severe HO. Having hypertrophy (spurs or excess bone growth around the joint) or ceramics was cited as increasing risk, but the increase didn't look scary to me - 1-5% of people with these risk factors developed the problem. If you are unfortunate enough to have fused hips, your risk is very high - up to 50% likely.
Here's a good overview article I found:

BTW- the above suggested that the timing of this is a few weeks after surgery.
Soooo. . . I'm glad I took Celebrex. It helped my pain, may have helped with HO, hasn't caused me to bleed despite my coumadin. My xrays 4.5 months out from the first hip showed no problem. Time will tell!
