Elbow, Wrist & Hand Review Flashcards
what is the first type of imaging usually done w/ EWH
radiograph
AP view of the elbow you can see what structures
carrying angle
humeroulnar joint
humeroradial joint
distal humerus
radial head, neck, tuberocity
proximal ulna
lateral view of elbow spatial relationships
olecrannon & fossa
superimposed epicondyles, circular trochlear sulcus directly below
lateral view of elbow continuity/structures
olecrannon
corinoid process
radial head
fat pads anterior & posterior to distal humerus
what sign can you see in the lateral view of the elbow
sail sign when effusion pushes fat pads upward/outward
AP view of the forearm includes what observations
entire length of radius & ulna
proximal & distal articulations
lateral view of the forearm observations include what
normal bowing of radius & ulna
elbow structures
radial head superimposed over coronoid process
proximal & distal articulations
hand PA view spatial relationships
long axis of 3rd metacarpal & long axis of radius
oblique line along met heads 3-5
overlapping met bases 2-5
overlap trapezium & trapezoid; pisiform & triquetrum
hand oblique view - what is the projection
45 deg rotation from PA position
digits do not superimpose
hand oblique view spatial relationships
IP & MCP joint spaces
hand lateral view - what is the projection
thumb magnified
overlaps phalanges, metacarpals, distal raidus & ulna
hand lateral view spatial relationships
displacement of fx fragments
long axes of radius, lunate, capitate
wrist PA spatial relationships
arch distortions like carpal subluxation/dislocations
overlap trapezium & trapezoid; pisiform & triquetrum
wrist oblique view - what is the projection
45 deg rotation from PA position
wrist oblique view spatial relationship / continuity
trapezium’s articulations
hamate
triquetrum
