29 terms · Includes hands, fingers, thumb and wrist

Hand position- PA Projection

Elbow 90 deg., arm fully supported. Hand open, fingers extended with palmar face in contact with IR, fingers seperated. Center ray is perpendicular to the thrid metacarpel joint.

Hand Xray image- PA Projection

Xray image shows the ulna and raduis, wrist bones, 1-5 metacarpels, proximal phalanges, IP Joints, Middle phalanges and the distal phalanges

Hand position- PA Oblique projection, lateral rotation

Elbow 90 deg, arm fully supported. Hand is rotated laterally, then hand is rotated to a 45-degree angle with IR. Stair step sponge is used for support and to help maintain position. Central ray is perpendicular to the third metacarpel joint

Hand Xray image- PA Oblique projection, lateral rotation

carpels, 1-5 metacarpels, proximal phalanges, middle phalanges, and distal phalanges are visible in image.

Hand position- PA Oblique projection- Lateral roation "modified Teacup" position

Elbow is 90 deg, arm fully supported.Used when not using the stair step sponge, from the lateral position, the hand forms a 45 deg angle with the IR. Central ray is perpendicular with the 3rd metacarpel joint.

Hand Xray Image- PA Oblique projection

ulna, radius, carpels, metacarpels, proximal phalanges, middle phalanges, and distal phalanges are visible in image.

Hand Position-Lateral- Ulnar and Fanned Fingers

Elbow is 90 deg, arm fully supported. Ulnar portion on arm is in contact with IR. Hand is in lateral position with fingers extended or can be supported on sponge and fanned. Wrist will be slightly pronated. Central Ray is perpendicular to second metacarpel joint.

Hand Xray Image- Lateral Ulnar projection

Ulna, radius, carpels, 1-5 metacarpels, and phalanges are visible in image.

Hand Xray Image- Lateral projection, Fingers Fanned

Ulna, radius, carpels, 1-5 metacarpels, and phalanges are visible in image.

Thumb Position- AP Projection

seated at end of table, arm abducted 90 deg, w/ forearm rotated internally into exaggerateed deg of pronation. Dorsal surface of the thumb is in contact with IR, coronal plane of thumb is paralell to IR, plane of palm is perp to IR. Central Ray is perpendicular to 1st metacarpel joint.

Xray Image - Thumb AP Projection

Trapezium, 1st metacarpel, ip joint, proximal phalanx and distal phalanx are visible in image.

Thumb Position- PA Oblique Projection

elbow flexed 90 deg and arm fully supported. Palm of hand is in contact with IR. Coronal plane of thumb will be 45 deg (oblique) to the IR. Central Ray is perpendicular to the first metacarpel joint.

Xray Image- Thumb PA Oblique Projection

Trapezium, 1st metacarpel, proximal phalanx, and distal phalanx are visible in image.

Thumb Position- Lateral Projection

Elbow flexed 90 deg, and arm is fully supported. With hand positioned for PA oblique thumb, patient flexes MCP joints 2-5 w/ fingers extened "tenting" hand until thumb is in lateral position. Central Ray is perpendicular to the first metacarpel joint.

Xray Image- Thumb Lateral Projection

Trapezium, 1st metacarpel, proximal phalanx, and distal phalanx are visible in image.

Thumb Alternative PA Position

If AP position is too painful for patient, this position can be used. Ulnar aspect of hand is in contact w/ IR and the palm of hand is perpendicular to IR. Thumb is supported by circle sponge, with coronal plane parallel to IR. Center ray is perpendicular to 1st metacarpel.

Xray Image- Thumb alternative PA Position

xray not as clear as AP Projection, 1st metacarpel, proximal phalanx and distal phalanx are still visable.

Wrist position- PA Projection

elbow flexed 90 deg, forearm resting on table. Anterior surface of wrist is in contact w/ IR. Fingers are flexed to form a loose fist, placing wrist in firmer contact with IR and opening intercarpel joint. Centrl ray is perpendicular to metacarpel base area.

XRay Image- Wrist PA Projection

Ulna, Ulna Styloid, Lunate, Triquetrium, Capitate, Trapezium, Schapoid, Radial Styloid and Radius are all visible in image.

Wrist position- PA Oblique Projection- Lateral Rotation

Uses triangle sponge. Elbow flexed 90 deg, forearm resting on table. wrist formas a 45 deg angle against sponge. Central Ray in perpendicular to base metacarpel range.

XRay Image- PA Oblique Projection- Lateral Rotation

Ulna, Ulnar Styloid, Lunate, Triquetrium, Trapezium, Schapoid, Radial Styloid and Radius are visible in image.

Wrist position- Lateral Projection

Elbow is flexed 90 deg, forearm is resting on table. MEdial surface of wrist is in contact with IR. Coronal plane of wrist is perpendicual to IR, fingers are together and extended. Central Ray is perpendicular to Styloid process of radius.

XRay Image- Wrist Lateral Projection

from bottom to top: Ulna, Radius, Scaphoid, Trapezium, and 1st metacarpel are visible.

Wrist position- AP Oblique projection- -medial rotation

elbow flexed at 90 deg, forarm is resting on table. Using triangle sponge. Inner surface of wrist is facing upward resting in triangle at 45 deg angle with IR. Central Ray is perpendicular to midcarpal base. (opposite rotation than reg oblique).

XRay Image- Wrist AP Oblique projection- medial roation

Bottom to Top: Distal Radius, Distal Ulna, Lunate, Scaphoid, Pisiform, Hamate, 5th metacarpal

Wrist position- PA Projection-- ulnar deviation

Same fingers as PA psition, then hand is deviated in direction of ULNA.Central Ray isPerpedicular, centered to scaphoid (point slightly medial to first metacarpel base).

XRay Image- PA Projection-- Ulnar Deviation wrist

Ulna, Radius, Radial Styloid, Scaphoid, 1st metacarpal

Wrist position- PA Axial Projection

Arm is extended and parallel to long axis of table. Wrist is positioned with anterior aspect on IR, pinky slightly spread more than other fingers. CENTRAL RAY IS ANGLED 20 DEG. in direction of ELBOW and centered to schapoid

XRay Image- wrist PA Axial Projection

Radius, Radial Styloid, Ulna, Ulnar Styloid, Scaphoid
