superior-lateral approach
Delto-pectoral approach
Remove the cutting guide assembly, add a third
(divergent) fixation pin through the middle hole of the
cutting plate to secure the assembly. Resect the humeral
head, aligning the saw blade with the superior aspect of
the cutting plate (Figure 18, option 1).
Note: the two external pins are parallel, this enables
the cutting plate to be reversed before being secured
with the third divergent fixation pin, providing a flat
cutting surface (Figure 18, Option 2).
place the humeral resection protecting plate onto the
resected surface to protect the bone from damage during
the following surgical steps (Figure 19).
pass a forked retractor under the scapula to lower the
humerus. if this provides a clear sight of the glenoid
surface, the resection level is correct. if not, a further
resection may be required.
