First 1000 uncemented implants and other data through August 2011 from Dr Gross is located here...
http://www.grossortho.com/forms/HSR%20consent%208_2011.pdfI held out on the uncemented until it hit the 3 year mark. It seems to be performing quite well. I know that all sorts of other surgeons 'survivor-ship' data gets mentioned in passing and without context, but I'm very appreciative of the fact that Dr Gross is so forthcoming with his results.
Interesting to note his failures (requiring revision) in the first 1000 un-cemented Biomet implants:
1. Femoral neck fracture: 6
2. Early femoral collapse (avascular necrosis): 2
3. Failure of acetabular ingrowth: 5
4. Adverse wear failure: 2
5. Deep infection with loss of implant: 0
6. Recurrent dislocations requiring revision: 0
7. Femoral component loosening: 0
8. Acetabular component loosening 0
9. Subtrochanteric femur fracture 1 (related to hardware removal)
I look at each failure mode as to how it might impact me and what I can do do not be a failure data point.
#1 - I'm past the 6 month mark and so that bodes well for me
#2 - Not sure what I can do about that, but my last x-ray showed no issues
#3 - I have the tri-spike cup (extra fixation for my freaky perthes hip!) that has had 0 failures as I understand it
#4 - My cup is in the mid 30 degree range and the failures came with 50+ degrees (crossing fingers)
#9 - I have no idea what that is, but it doesn't sound good.
Headed off to play two hours of full court hoops tonight. That's enough internet and data... time to suck it up on the basketball court
