more and more people are hearing
about the benefits of hip resurfacing
over conventional total hip replacement.
This relatively new technology
started with the invention of
the “Birmingham Hip replacement”
approximately 15 years ago.
is a Hip Resurfacing?
Hip Resurfacing instead of the Femur being
cut through just below the head, the head
of the femur is capped with a ball cap.
This cap is then inserted into the cup

prepared hip socket Indications are that

resurfacing is most appropriate for physically
active patients with good bone quality
and adequate femoral and acetabular bone
stock. Such patients will generally be
under the age of 65. However patients

remaining bone stock is adequate

The prosthesis may be constructed
of various materials but is usually
made of forged steel rather than cast
steel (these were prone to break).
The exterior of the unit is rough
and porous so that the unit when press
fitted with combine with the bone,
which actually grows into the unit.
This creates an immensely strong bond,
which is hard to separate (rather
like barnacles on a ship).
ball will probably be titanium, cobalt
crome plated or ceramic (there is some
concern from patients as to whether the
ceramic ball will break but providing
the unit is properly engineered this is
extremely unlikely). The advantage of
ceramic is that it is both extremely robust
and has a very low friction coefficient,
which means a low wear rate.
Sometimes the cap
may be ceramic but these in rare cases
have been known to break under excessive
stress conditions. One popular combination
is a ceramic ball and composite cap, these
are found to have less wear. Modern units
can wear at the rate of 1 micron a year;
some years ago wear rates were more likely
200 microns a year so great improvements
have been made. One thing to be weary
of is ensure that your surgeon is fitting
a leading manufacturers unit not a generic
copy such as those that you may receive
in cheaper surgery. If it is possible
find out what the surgeon will be fitting
and do they fit a very good standard of
unit. If you are a private patient that
is paying their way you should be able
to ask these questions and receive a satisfactory
answer. Government health services will
fit units from a standard procurement
list. This list may be quite limited by
the number of models and sizes, as health
services seek discounts by bulk purchasing
methods. In addition the prosthesis on
the procurement list may be dated as it
takes time for new products to be accepted.
