11a. Acetabular Reaming
It is important to start reaming with the smallest
diameter grater reamer available, perpendicular to
the acetabulum, in order to find the true acetabular
floor. Sequential reaming then follows, ensuring that
the reamer handle is angled at the same orientation
of the component to be implanted. (45 degrees of
inclination and 20 degrees of anteversion) Care must FLV HERE
be taken at this stage to ensure that the anterior
and posterior columns of the acetabulum are not
eroded, as this will affect the overall stability of the
component. It is recommended that the acetabulum
should be reamed either 1mm or 2mm smaller,
depending on bone quality, than the acetabular

component to be implanted. (Figure 18)
11b. Acetabular Gauging
After reaming, the acetabulum is gauged for
sphericity and size, using the acetabular gauges
provided. These gauges contain windows that allow
direct visualisation of the acetabular floor and also
test the stability of the acetabular component prior
to implanting the actual acetabular component. The
gauge selected should correlate directly with the FLV HERE
size of acetabular component to be implanted. (For
example, a 56mm acetabular implant requires the
acetabulum to be reamed to 54mm diameter. This
54mm reamed acetabulum is then gauged with a
56mm gauge).
