selection factors can favorably impact modern
resurfacing outcomes:no large femoral head cyst;
younger than 65 years old; and
no prior hip surgery.
“My current ideal indications for hip
resurfacing are patients age less than 60 years,
risk index less than or equal to 3,” he said.
The risk index – surface arthroplasty risk index
(SARI) – is a tool for
Half of the stitches or staples are normally
removed after 14 days. The remaining half is
removed after 16 days. Depending on the
individual patient, one can decide to remove the
staples later on. Staples are removed with a

This is peculiar to resurfacing as the cup for

Nearly all THR cups are only portions ( arc) of a

There has been some recent confusion about
different types of

The anterior vs. posterior debate isn’t going to be resolved
by one study of electrode blood flow. Most surgeons would
agree that blood flow to the femoral head (most of which
comes backwards via the femoral neck) is theoretically
better preserved through an anterior approach. Much of this
info comes from the work of Ganz, who did a lot of cadaver
dissection to prove this.
Does the length of incision influence the rehabilitation?
No! A bigger incision does not mean that there will be more
damage to the muscular structures. On the contrary, if you
need a bigger incision to get better exposure, the placement
of the implant can be done more precisely. Even with an
incision of 30 cm you are able to walk well after 24 hours.
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.

patients who followed those rules. In young men

How old is the BHR / Conserve Plus (C+) procedure?
BHR procedure is developed in 1996/97. The first
metal-on-metal resurfacing is from Feb. 1991. The resurfacing is
already 40 years old, metal-on-metal is 40 years old (the oldest
dates from 1938!). Both ideas were put together by Mr. McMinn in
1989. The Conserve Plus design was introduced by Dr. Amstutz in
Cysts are very common in
arthritic hips and can usually be seen on
x-rays. Most of the time they are not a problem
with resurfacing because they are small and in

femoral head for a resurf. Most larger ones can
be filled with a cement of bone chips and still
