select the appropriate proximal reaming guide size
(Figure 49). For example, if a 12 mm intramedullary
reamer and a 12 mm cutting handle were previously used,
select the 12 mm proximal reaming guide.
slide and screw the internal rod of the reaming guide
holder into the holder main body. Then slide the reaming
guide into the reamer holder and fasten the two parts
together by firmly screwing in and tightening the upper
round handle (Figure 50).
push the holder horseshoe plate fully down (Figure 51).
slide the proximal reaming guide down into the
intramedullary canal, rotating it if necessary to ensure that
the horseshoe plate sits flat on the bone resection surface
(Figure 52).
Drive the proximal reaming guide down until achieving
complete contact between the metal block and the
resection bone surface (Figure 53).
unscrew the upper round handle of the holder and
remove the holder, leaving the proximal reamer guide in
place (Figure 54).
The subsequent surgical steps depend on whether the
humeral implant chosen is cementless or cemented. For
cementless implants, see pages 27-35, for cemented
implants see pages 36-37.
