Mr. McMinn: The evidence
from a DEXA study on BHR patients published from
Japan is that the bone density in the proximal
femur returns to normal 1 year after operation.
The at-risk period for femoral neck fracture
following the BHR is in the 6 months after
surgery. I advise patients not to return to
impact sport for 1 year after surgery. For those
patients who want to road run, I get them
running on a treadmill at 10 months post-op and
they resume road running at 12 months post-op.
My unit published on activity level after
resurfacing some years ago in a group of
patients who followed those rules. In young men
with a single osteoarthritic hip resurfaced, 92
% played sport and 62 % played impact sport. The ladies were not quite
as active, but you can see from the publication
that they still had an impressive activity
level. In the total group their 10 year implant
survival is 99.8 % showing that high activity
introduced at a sensible time does not
deteriorate the results. “
