Starfire
This portion of the humerus articulates with the radius.
How the hand should be positioned for a lateral humerus.
What is rotated medially?
This is where the CR is directed for an AP Humerus.
What is midpoint of the humeral shaft?
This structure is shown in profile on a lateral projection of the elbow.
What is the Olecranon process?
These two structures primarily form the hinge-like movement of the elbow joint.
What are the trochlea and trochlear notch?
This projection will demonstrate anterior and posterior displacements.
What is a lateral?
The humeral epicondyles will be parallel to the IR for this elbow projection.
What is the AP projection?
This projection contains the radius, ulna, elbow joint and wrist joint.
What is a Forearm projection?
This structure will be free of superimposition on a medially rotated elbow.
What is the coronoid process.
The joint classification of the proximal radioulnar joint.
What is a Pivot joint?
Internally rotating the hand and upper limb places the humerus in this position.
What is the lateral position?
Degree of elbow flexion for a lateral forearm.
What is 90 degrees?
These should all be in the same plane for a lateral projection of the elbow.
What are the forearm, elbow and humerus?
This projection will show the humeral head and the greater tubercle in profile.
What is the AP Humerus?
The greater tubercle, capitulum, and radial head have this location in common.
What is located laterally?
Often associated with injury to the elbow even when no fracture is evident.
What are the fat pads?
A patient will be asked to do this right before an exposure of the humerus is taken.
What is suspending respiration?
Located in the distal radius and articulates with the head of the ulna forming the distal radioulnar joint.
What is the ulnar notch?
The radial head and neck will be seen without superimposition on this projection.
What is lateral (external) rotation?
This is the most proximal and posterior feature of the ulna.
What is the Olecranon process?
The radial head fits into this depression on the lateral aspect of the coronoid process.
What is the radial notch?
Degree of elbow rotation needed for a medial oblique elbow projection.
What is 45 degrees?
Positioning error on a lateral forearm where the distal radius is anterior to the ulnar head.
What is under rotation of the wrist?
This projection best demonstrates the olecranon process in profile.
What is a lateral view?
This occurs radiographically when an AP elbow is taken with elbow flexion and the humerus and forearm elevated.
What is foreshortening?
