HUMERAL PREPARA
Position the flexion-extension axis drill guide on the distal
humerus. It should sit with an approximate angle of 45°
anteriorly (fig. 20a & 20b).
TIP
The assembled drill guide should appear to be pointed
approximately 45° anterior to the coronal plane. (fig. 20b).
The cannulated screw should be placed over the drill hole
previously marked on the capitellum.
The medial notch of the guide assembly is placed on
the anterior and inferior portion of the medial epicondyle
at approximately 45° anteriorly.
The center of the medial notch should be roughly at the center
of the medial ridge of the trochlea such that an axis pin would
appear to exit at the anterior and inferior edge of the medial
epicondyle’s intersection with the trochlea (fig. 20a).
Drill the flexion-extension axis and then remove the guide
(fig. 20c).
As a check, reinsert the flexion-extension pin to confirm
correct alignment (fig. 21).
