37
Essential projections for digits 2-5?
PA, PA Oblique, Lateral
38
PA Positioning for digits 2-5?
Place hand prone flat on surface, center CR to the PIP, collimate to edges of the finger and 1.5 inch past knuckle
39
PA oblique positioning for digits 2-5?
Angle hand 45 degrees to IR, CR enters at the PIP, collimate to the edges of finger and 1.5 inches past knuckle
40
Evaluation of PA digit positioning
No rotation, concave phalanx bones, open IP and MCP joints (finger flat)
41
PA Oblique digits 2-5 evaluation
Hand at 45 degrees, open IP and MCP joints, proximal phalanx and MCP demonstrated without superimposition of adjacent digits
42
Lateral digits 2-5 positioning
Reduce magnification by placing the digit in a way where it is closest to the IR, flat, straight, lateral, injured finger is the only one extended the rest are flexed toward the hand, CR entering at the PIP joint
43
Lateral evaluation of digits 2-5
True lateral, look for outline of soft tissue, look for a straight line on one side of the phalanx and a curved line on the other (anterior surface of the phalanges should be concave), open IP joint spaces,
44
Essential projections for the thumb
AP, PA oblique, lateral
45
AP positioning for the thumb
Hand in extreme internal rotation, flat on surface, posterior surface of thumb in contact with the IR, CR centered at MCP, collimation includes the entire thumb down to the trapezium carpal bone and surrounding soft tissue
46
AP thumb evaluation
No rotation, shafts of metacarpal and phalanges should be concave on both sides, open IP and MCP joints, anatomy for distal tip of thumb to trapezium demonstrated, equal amounts of soft tissue demonstrated
47
PA oblique positioning
Anterior part of hand flat on the IR, thumb in neutral position gives an natural 45 degree angle, CR enters at the MCP, thumb to trapezium in collimation field
48
PA oblique evaluation
Proper rotation of 45 degrees, anatomy from distal tip of thumb to trapezium demonstrated, open IP and MCP joint spaces
49
Lateral thumb positioning
Flex fingers under hand, turn thumb so lateral side is resting on the IR (mediolateral projection), CR enters at the MCP, collimate thumb to trapezium,
50

52
Why use the extension lateral position of the hand?
To look for foreign bodies or use if patient can not fan fingers
53
PA positioning of the hand
Hand flat on palmar surface, fingers straight and spaced out, CR entering at the MCP of the 3rd metacarpal, collimation includes the entire hand fingers and wrist to one inch of the distal radius and ulna, hand and arm in the same plane

56
PA oblique evaluation of the hand
Proper 45 degree rotation, open IP and MCP joint spaces, no soft tissue over lap of the digits, anatomy from the distal phalanges to one inch of the distal radius and ulna
57
Lateral (fan) positioning of the hand
Place the medial side (pinky side) of the hand on the IR, elbow flexed 90 degrees, forearm and hand in same plane, make an okay sign with hand and then straighten and space out (fan out) each digit to make them free of super imposition, ulna and radial styloid process superimposed, CR entering at the 2nd MCP, collimation should be of the distal phalanges to one inch of the distal radius and ulna
58
Lateral extension position of the hand
Place the medial side (pinky side) of the hand on the IR, elbow flexed 90 degrees, forearm and hand in same plane,ulna and radial styloid process superimposed, phalanges superimposed, first digit abducted from Palm to form right angle, CR entering at the 2nd MCP, collimation should be of the distal phalanges to one inch of the distal radius and ulna
59
Lateral evaluation of the hand
Fan - phalanges free of superimposition Extension - phalanges superimposed Both - metacarpals and distal radius and ulna superimposed, extended digits
60
Lateral forearm evaluation criteria
Wrist to distal humerus demonstrated, superimposition humeral epicondyles, superimposition of the distal ends of the radius and ulna, elbow flexed at 90 degrees, radial head superimposed over coronoid process, radial tuberosity pointing anteriorly
61
Projections for an elbow
AP, AP oblique, lateral
62
AP elbow positioning
60 @ 2, supinate hand, extend arm and elbow flat on IR, hand and upper limb in same plane, CR centered at mid elbow, humeral epicondyles parallel with IR, collimation includes distal humerus radioulnar articulation and proximal radius and ulna
