Hand and Wrist Projections
Wrist: lateral projection (part position)
Flex elbow 90 degrees or fully extend elbow. ULNAR surface against IR. Wrist in true lateral position. Center IR to wrist joint
List the essential projections for the wrist
PA lateral PA oblique, lateral rot. PA ulnar deviation Scaphoid PA Axial Stecher method Carpal canal tangential Gaynor hart method
Hand: lateral projection (part position)
Ulnar surface resting of IR; extend fingers, with first digit placed at right angles to the palm, separate (fan) the digits, center MCP joints to center of IR
Hand: PA oblique projection, lateral rotation Collimation
1 in on all sides of hand, inc. 1 in proximal to ulnar styloid
Hand: PA Projection (Collimation)
1 in on all sides of hand, including 1 in proximal to ulnar styloid
Hand: lateral projection Collimation
1 in on all sides of hand, including 1 in proximal to ulnar styloid
Scaphoid PA Axial: Stecher Method Collimation
2.5 in proximal and distal to the wrist joint and 1 in on sides
Wrist: PA oblique, lateral rotation Collimation
2.5 in proximal and distal to the wrist joint and 1 in on sides
Wrist: PA projection Collimation
2.5 in proximal and distal to the wrist joint and 1 in on sides
Wrist: lateral projection Collimation
2.5 in proximal and distal to the wrist joint and 1 in on sides
Wrist: PA projection, Ulnar deviation Collimation
2.5 in proximal and distal to wrist joint and 1 in on sides
Carpal Canal: Tangential Projection (Gaynor-Hart Method) CR
Dir. to palm of hand at a point app. 1 in distal to the base of the 3rd MC + at an angle of 25-30 degrees to long axis of hand.
Wrist: PA oblique, lateral rotation
From the pronated position, rotate the wrist laterally until it forms a 45 degree angle with plane of IR
Carpal Canal: Tangential Projection (Gaynor-Hart Method) part position
HYPEREXTEND WRIST, center IR to joint at level of RADIAL STYLOID. Place long axis of hand as vertical as possible, rotating slightly towards radial side. Have patient grasp fingers with opposite hand to hold wrist in position
Hand: PA oblique projection, lateral rotation part position
Hand pronated, rotate hand laterally until MCP joints form 45-degree angle with IR. Spread fingertips. May use a 45-degree accessory sponge. The digits should be parallel with the IR. When the injury is only in MC area, the fingertips may touch the IR.
Carpal Canal: Tangential Projection (Gaynor-Hart Method) Collimation
Include palmar aspect of wrist, proximal one third of MC's, and 1 in on sides
Specifically, which bones are superimposed in the fan lateral?
Metacarpals and proximal phalanges
List the essential projections for the hand
PA PA oblique, lateral rotation lateral
Wrist: PA projection, Ulnar deviation CR
Perpendicular to SCAPHOID; CR angulation of 10-15 degrees. Prox or dist sometimes required for clear delineation
Wrist: PA oblique, lateral rotation CR
Perpendicular to midcarpals
Wrist: PA projection CR
Perpendicular to midcarpals
Scaphoid PA Axial: Stecher Method CR
Perpendicular to the table and directed to enter the Scaphoid
Hand: PA Projection (CR)
Perpendicular to third MCP joint
Scaphoid PA Axial: Stecher Method (Part position)
Place one end of IR on a sandbag so that the finger end of IR is elevated 20 DEGREES (Inclined toward elbow). Place wrist in PA POSITION, centering carpals app. a half inch above midpoint of IR
Wrist: PA projection, Ulnar deviation
Position wrist and center IR as for PA wrist. TURN HAND OUTWARD without moving the forearm until wrist is in extreme ULNAR DEVIATION
Wrist: PA projection (part position)
Rest forearm on table, with long axis of forearm parallel to long axis of IR. Center to carpals. ARCH HAND SLIGHTLY at joints flexing digits which places wrist closer to IR
Hand: PA Projection (Position part)
long axis of arm to long axis of IR. Palmar surface down, spread digits slightly, Center IR to MCP joints.
Hand: lateral projection CR
perpendicular to SECOND digit MCP joint
Hand: PA oblique projection, lateral rotation (CR)
perpendicular to third MCP joint
Wrist: lateral projection CR
perpendicular to wrist joint
