The extension (or straightening) of the elbow stops when the proximal end of the ulna engages the <u>coronoid fossa of the humerus</u>.
The olecranon process is the large, blunt, proximal tip of the ulna. The rough posterior surface of the olecranon process is the distal attachment for the triceps muscles.
An olecranon fracture is a break in the “pointy bone” of your elbow that sticks out when you bend your arm, which is actually the end of the ulna. This type of fracture is common and usually occurs in isolation (there are no other injuries) but can also be a part of a more complex elbow injury.
The ulna has a thick proximal stop with distinct methods. The olecranon procedure is the huge, blunt, proximal tip of the ulna. The rough posterior floor of the olecranon system is the distal attachment for the triceps muscles.
