uncemented hip

[bri]

My doctor told me I would have a uncemented cup.I would not be able to put weight on it for 3-4 weeks.Does this mean that you have to put 100% of the weight on the crutch? I see videos of people walking right after surgery ect. Just sounds like your cup could come loose or something before the bone is 100% grown into the cup. You would think putting screws in would help hold it in place better.

Hey Bri,

I think it depends on the type of damage you have. Who is your doctor and how many HRs has he/she done? I know Dr. Gross has had a lot of success with uncemented cups, so that is a reliable technique.

At one point you were considering doing both, is that still the case? Were you able to get your XRays to Dr. Gross or one of the other Doctors available for free consultations?

I'm not sure how you would do 100% non weight bearing, especially with both being done. Maybe someone else knows, that's why getting an opinion from one of the doctors available here would be good for you.

       Bri, the implants are pounded into place.  Unless you have a very odd shaped hip (mine was a little oval but not out of spec) the uncemented cup is literally pounded into place.  As long as you don't overdo the stresses by running, jumping or falling it should stay right where it is after surgery.  Same with the femoral component. I know some have had a spiked cup implanted due to shape or other issues.  The less hardware the better I think. 
      As far as the recovery weight bearing, Dr. Gross uses a rapid recovery with 90 percent load bearing or the slower, precautionary recovery with 10 percent weight bearing.  It doesn't have anything to do with the lack of cement, rather with the condition of the femur or other bone issues. Not sure if it is routine with bilater surgeries.  Lots of bilats here though that could tell you.  Good luck, Curt

Virtually all acetabular components are biological fixation ( bone ingrowth)
I know in some revisions etc they cement the cup. It is very well wedged in they reem 1-2mm less and put a larger device In so the bone already hold it real well. The cups also generally have anti rotation flanges on them which will stop rotational movement.
Obviously ask your surgeon but find a surgeon who is a hr advocate and has done a good number and most important good results!
