These numbers were all from the Australian Hip
Registry which was
established in 1999. A total of 140,018 patients
registered with
160349 procedures out of which 8361 were
resurfacings.
The BHR was started in 1999 and the competitors
started in 2000 and
2001. This is the latest data published in that
registry. I am sure
there are more details in the registry itself,
but this is all the
data, well minus 1% of resurfacing done in
Australia. I think it is
somewhat a good overall feel for the results
considering it is
gathered over almost the same amount of time,
from all of Australia
in all patients given the procedure which would
cover all doctors, etc.
