Operative Technique
2. Templating
It is important to note that to carry out accurate templating of the anatomy, the x-ray
magnification must be identical to the template used. Failure to follow this instruction will
result in the wrong size implant being selected or incorrect measurements being taken. See
chart below for details of Recap/Magnum implant sizing.
Prior to surgery, the decision must be taken as to which method of guide pin positioning is
to be undertaken. The ReCap
®
instrumentation offers two methods for completing this stage
of the operation. The two methods of guide pin positioning are; a) utilising the Recap KS
Alignment Device, or b), utilising the guide pin alignment frame and laterally positioned pin.
Once the decision has been made as to which method is to be employed, it is important that
the correct pre-operative x-ray templating procedure is followed.

NB: When implanting the oversize acetabular shells use the insertion instruments for the equivalent standard acetabular shell
e.g. When using the 58mm x 50mm oversize acetabular shell use the 56mm acetabular insertion instruments
