Perspective Patients and Patients often ask if the stem of the acetabular component of the BHR iscemented.  The stem itself is not, the cement is placed into the cup of the
component.  An explanation from Mr. McMinn’s “Modern Hip Resurfacing” book
explains the process:

MODERN HIP RESURFACING by Derek McMinn Editor

“At this stage, the central hole in the femoral head and neck is enlarged
from a parallel-sided hole to a taper by the use of a taper drill. I did not
formerly perform this maneuver routinely, but now I do.

Press-fitting the taper stem of the BHR femoral component into a parallel-sided
drill hole is perfectly satisfactory in normal bone. However, in sclerotic
bone, the press fit is very tight and can cause incomplete seating of the
femoral component with a requirement for heavy hammering. In order to
prevent these difficulties, I now convert the parallel-sided drill hole in
the femoral head and neck into a taper drill hole in all cases…:

… The femoral head is filled one-third full with antibiotic Simplex cement.

The femoral component is tipped so that the cement pours onto all the
femoral fixation surfaces…

At precisely 1 minute from mixing, the femoral component is inserved onto
the femur. ”
