ReCap™ Total Resurfacing System
6b Guide Wire Placement – Alignment
Frame with Lateral Pin
Before the guide wire alignment frame can be
employed, the 4.0mm Steinman pin must be inserted
into the lateral cortex. This pin is driven into the lateral
cortex, parallel to the femoral neck and slightly posterior
to the mid line of the femur. This slightly posterior
location helps achieve the correct anteversion.
The desired position of the femoral alignment pin
will be known from the preoperative templating. This
measurement should be translated onto the lateral
cortex measured down for the tip of the greater

trochanter and the alignment pin inserted through the
fibres of vastus lateralis. The jig can now be attached as
shown (Figure 10).
Before advancement of the guide pin can take place, the
stylus assembly is set to the diameter of the resurfacing
head selected and rotated around the femoral neck
and head/neck junction, in order to determine whether
or not notching will occur (Figures 11 & 12). When the
stylus can be passed around the femoral neck, then
the central guide tube is locked into position. Any
fine tuning can now take place. Once happy with the
positioning of the guide tube, the guide wire is advanced

through the guide tube.
