7. HUMERAL PREPARATION
1 Flexion-extension axis determination
Mark the center of the flexion-extension axis on the
capitellum side with the capitellum radii gauge with the 3 mm
self-drilling pin to reference the proper position of the drilling
guide on the flexion-extension axis (fig. 18).
The location of the axis is typically at the site of attachment
of the lateral ligaments to the lateral epicondyle.
If the capitellum is imagined to be a circle when viewed
from the lateral side, the flexion-extension axis is located
at the center point of this circle.
The circular gauge is a useful tool to visually estimate
this location.
Note
The key to a successful outcome is the accurate determination
of the flexion-extension axis.
Remove the central portion of the distal humerus
(trochlea, sulcus and lateral ridge) to the proximal aspect
of the olecranon fossa with either an oscillating saw or large
rongeur (fig. 19).
