What is the patient position for humerus, shoulder, scapula, clavicle and AC joints? Patient is erect with back touching IR or supine on the table.
What is the part position for a PA hand? Hand open, fingers extended with palmer surface in contact with IR. Fingers moderately separated
What is the part position for a PA Obliue hand? From PA position the hand is rotated laterally rotated to place the anteromedial aspect in contact with IR
What is the part position for a lateral hand? Ulnar aspect of hand is contact with IR with coronal plane of hand perpendicular to IR, thumb is positioned as for a PA thumb. Digits 2-5 are straight
What is the part position for a lateral fan hand? Ulnar aspect of hand is contact with IR with coronal plane of hand perpendicular to IR, thumb is positioned as for a PA thumb. Digits 2-5 are spread out to prevent superimposition
What is the CR for a PA hand and PA oblique hand? perpendicular to third MCP joint
What is the CR for a lateral hand and fan lateral perpendicular to second MCP joint
What structures are seen in PA hand radiograph? Entire hand (including fingertips), carpus and most distal aspects of radius and ulna
What structures are seen in PA oblique hand radiograph? No or minimal overlay of metacarpalshafts with some superimposition of metacarpal heads and bases
What structures are seen in a lateral hand radiograph? Superimposition of second through fifth phalanges (fan lateral - phalanges individually demonstrated. Thumb is seen in PA projection
What is the part position for an AP thumb? Patient leans forward arm abducted 90 degreeswith forearm internally rotated into an exaggerated degree of pronation. Dorsal surface of thumb is in contact with IR. Plane of palm of hand is perpendicular to IR.
What is the part position for an PA oblique thumb? Palmar surface of hand is in contact with IR as for PA Projection of hand. Coronalplane of thumb will be 45-degrees to plane of IR.
What is the part position for a lateral thumb? Beginning with hand positioned for PA Oblique thumb, patient flexes MCP joints 2-5 with the with the fingers extended "tenting" hand until thumb is lateral.
