- Discussion:
- together w/ proximal portion of the coronoid process, olecranon forms
greater sigmoid notch of the ulna, a deep depression that serves as
articulation w/ trochlea that serves as the articulation w/ trochlea
which allows motion only in anteroposterior plane and provides
stability to the elbow joint;
-
articular cartilage surface is interrupted by a transverse line of bone,
"bare area" located midway between tip of olecranon & coronoid process;
- if this is not recongnized during reconstruction of frxed olecranon,
there is temptation to eliminate any area uncovered by cartilage;
