, Functional Anatomy
• Hinged joint with
single axis of rotation
(trochlear axis)
• Trochlea is center
point with a lateral
and medial column
, Functional Anatomy
• The distal humerus
angles forward
• Lateral positioning
during ORIF facilitates
reconstruction of this
angle
, Surgical Anatomy
• The trochlear axis compared to longitudinal
axis is 94-98 degrees in valgus
• The trochlear axis is 3-8 degrees externally
rotated
• The intramedullary canal ends 2-3 cm above
the olecranon fossa
