Chap 4 RAD 114
Describe the special projection you will perform on a patient who presents with a possible tear of the ulnar collateral ligament of the wrist
Folio method
Describe the radiographic imaging procedure which will best identify a Bennett's fracture
AP axial projection (modified Roberts method)
Describe the projections of the elbow which you may perform if the patient presents with a possible nondisplaced fracture of the coronoid process
AP oblique medial rotation, trauma axial lateromedial and mediolateral, ( I think coyles method is the correct one)
Describe a projection which demonstrates the carpal joints on the ulnar side of the wrist
PA wrist with radial deviation
What projections will you preform for the patient who presents with severe elbow trauma
(Axial, elbow flexed 90 degree if possible hand pronated) Jones method, 2 partially flexed AP elbows
What is the Jones method
Acute flexion projection of the elbow, AP projection of elbow (old terminology)
The projection you will perform if the patient presents with a request for the Norgaard method
Ball catcher position
The projection that you will perform with the patient who presents with a possible fracture of the coronoid process
Coyles method
Describe the positioning of the elbow using the trauma lateral Coyle method
Elbow flexes 90 degrees if possible, hand pronated, CR 45 degree from elbow
Describe the projection that you will perform with the patient who presents with a history of calcifications in the carpal sulcus
Gaynorhart method
describe the radiographic imaging projection which best suited for a patient who is unable to perform the ulnar deviation position
Hand elevated on 20 degree sponge or have patient clench the fist
How will you correct the positioning for your PA projection of the hand which reveals that the carpals and distal forearm have been cut off
Include 1 in of distal radius and ulna, open up the collimation
You used 60 kV on a PA projection of the wrist prior to post - reduction and application of a fiberglass cast. How would u adjust technique for the fiberglass cast
Increase kV 3 to 4
Describe a projection of the elbow which best demonstrates the olecranon process in profile
Lateral
Describe the position of the elbow that will best demonstrate an elevated or visible posterior fat pad
Lateral true 90 degrees (lateromedial projection)
How will you correct the positioning for your lateral elbow projection which reveals that about half of the radial head is not superimposed over the coronoid process
Make sure that the hand and forearm is in true lateral position and that 90 degree angle of elbow is correct
How will you correct the positioning for your PA scaphoid projection which reveals superimposition of the carpal bones located on the radial aspect
Make sure that the patient is ulnar deviating to open up the medial carpals
How will you correct the positioning for your AP projection of the elbow which reveals that there is complete separation of proximal radius and ulna
Rotate arm medially and epicondyles are parallel
How will you correct your AP medial oblique projection of the elbow which reveals that the radial head is superimposed over the coronoid process
Rotated to medially, rotate arm until distal humerus and anterior surface of elbow are rotated 45 degrees
How will you correct the positioning for your PA oblique image of the hand which reveals superimposition of the 4th and 5th metacarpals
Rotated to much, fan fingers, use radiolucent block to support digits
Describe the radiographic imaging procedure which will best identify a smith fracture
Wrist and forearm
