Operative Technique
7. Gauging Femoral Neck
As a final check prior to over drilling the guide wire,
its correct positioning can be verified using the neck
gauges. These gauges are size specific and designed
to check the guide pin is centrally positioned within the
femoral neck. (Figure 13) FLV HERE
Slide the appropriate size neck gauge over the guide
wire and rotate it around the femoral neck. If at any
position the point of the stylus touches the femoral
neck, it may be necessary to reposition the guide or
increase the size of the femoral resurfacing head. Be

aware that if the second option is chosen, it will also
be necessary to increase the size of the acetabular
component. Once the placement of the guide wire has
been verified, it can be advanced into the lateral cortex.

8. Drilling Femoral Head
The cannulated drill is placed over the guide wire
and advanced until the correct depth is reached.
The depth is determined by the colour code of the
size of implant to be used. For example, if a 50mm
ReCap
®
resurfacing component is to be implanted,
the instrument colour code is two white rings. The
depth to which the cannulated drill is advanced is,

therefore, the second white ring. The cannulated drill
and guide wire can then be removed. (Figure 15)
