A unique feature is a lack of the olecranon process on the ulna.
It is also distinguished by the presence of a trochlear-form ulnar articulation and a distal olecranon fossa.
This is because in early life, olecranon is thick, short and much stronger than the lower extremity of the humerus.
It also prevents the elbow joint capsule being pinched in the olecranon fossa during extension of the elbow.
The forelimbs are robust, with enlarged olecranon and other processes associated with strong muscle attachment.
Olecranon is the bony point of the elbow.
A hole is then drilled in the olecranon and a gauge wire is then looped in the hole.
The right ulna is small and slender, is missing an olecranon, and has a well-marked ridge.
