HUMERAL PREPARA
Using and interpreting the offset gauge
Starting with the thickest portion of the offset gauge,
slide it along the intramedullary alignment rod.
If this portion can be inserted in between the
flexion-extension axis pin and the alignment rod, then
the offset is ANTERIOR (fig. I).
If the thickest portion cannot be inserted, rotate
the gauge and try inserting the thinnest portion of
the gauge. If it fits in between the axis and the
alignment rod, then the offset is CENTERED (fig. II).
If the thinnest portion of the gauge cannot be inserted,
then the offset is POSTERIOR (fig. III).
3 Humeral Distal Preparation
Assemble the appropriate size humeral trochlea cutting block
to the trochlear cutting guide support with the assembly
screw. Do not fully tighten the assembly screw at this time
(fig. 25a).
Position the cutting guide on the flexion-extension axis pin
and align with the medullary alignment rodas shown (fig. 25b).
