The olecranon is a large, thick, curved eminence, situated at the upper and back part of the ulna.
Zumaya fractured his right olecranon, which is the bony tip of the elbow right under the skin.
The official diagnosis is a fractured right olecranon, which is the bony tip of the elbow right under the skin.
On the back of the olecranon is a smooth triangular subcutaneous surface, and running down the back of the forearm from the apex of this triangle the prominent dorsal border of the ulna can be felt in its whole length: it has a sinuous outline, and is situated in the middle of the back of the limb above; but below, where it is rounded off, it can be traced to the small subcutaneous surface of the styloid process on the medial side of the wrist.
There is also a possibility of permanent nerve damage of the Ulnar nerve, because it runs through a groove on the olecranon and in most cases, has to be moved out of the way in order to reach the bone to put in metal hardware to fix the break.
An olecranon break is painful and will take occupational therapy rehabilitation.
Dr. Johnson says if this is what he called an olecranon fracture -- now, that's one affecting the bone on the pinky ringer side -- the pinky finger side of the forearm, right here, then she could be able to travel -- Wolf, this kind of break in this area right here, by this side of the forearm, which is up near the elbow, shouldn't be serious enough to keep her from traveling.
In the humerus, drill-mangabeys, drills and mandrills share a notably broad deltoid plane, a proximally extended supinator crest, a broad flange for the brachialis, and a narrow olecranon process with a deep lateral ridge, and there are also characters in the radius and ulna that unite these monkeys to the exclusion of their close relatives.
Reduction is to be effected by separating (the bones) as much as possible, so that the end (of the humerus) may not come in contact with the olecranon, and it is to be carried up, and turned round, and not forced in a straight line, and, at the same time, the opposite sides are to be pushed together, and propelled into their proper place.
When the elbow-joint is displaced or dislocated to the side or outward, while its sharp point (olecranon?) remains in the cavity of the humerus, extension is to be made in a straight line, and the projecting part is to be pushed backward and to the side.
