superior-lateral approach
Delto-pectoral approach
pre-drill the cortical bone through the cutting plate using
a 3.2 mm drill bit, and insert the two fixation pins to fix
the cutting plate to the humerus (Figure 17).
Following the colour code guidance, the surgeon should
resect 1 - 2 mm of the proximal area of the greater
tuberosity (at the level of the supraspinatus insertion in an
intact shoulder).
Note: the cutting angle is 155°, and therefore
different from the anatomical neck/shaft angle of
135°. 155˚ is recommended for reverse shoulder
systems.
