Latitude Elbow Prosthesis
Slide the cutting block off the stabilizing pins and remove
them with the pin puller (fig. 29).
Lack of anatomical landmark
In the absence of anatomical landmarks on the trochlea,
use the modified humeral cutting guide.
Assemble the cutting block to the “No trochlea” support
noting either right or left with the assembly screw.
Slide the completed assembly over the medullary
alignement rod until the flexion/extension line figured
on the block is correctly positioned.
Remove the bony bridge between the drill holes with
a straight osteotome, microsaggital saw or rongeur
as necessary (fig. 30).
If the medial trochlea has been excised, mark where
the flexion-extension axis was, using a marking pen.
Smooth the cut surface with a humeral broach or burr (fig. 31).
