forearm x ray

forearm x ray AP and Lateral radius and ulna x ray

forearm x ray (x ray forearm ap lateral)
AP PROJECTION ( for ap forearm x ray)
ANATOMIC STRUCTURES
Entire radius and ulna
Proximal row of carpal bones
Elbow joint (including distal humerus)
FILM SIZE
11 X 14 in. (30 x 35 cm)
Divide film in half, lengthwise
PATIENT POSITION
Seat patient at end of table to place entire upper extremity in same horizontal plane as film.
Place lead shield over patient to protect gonads.
PART POSITION
Fully extend elbow, and supinate hand (palmup).
Align long axis of unmasked 2 of cassette with long axis of forearm.
Center unmasked 1/2 of cassette to midpoint of forearm.
Have patient lean laterally to place humeral epi-condyles parallel to cassette.
CENTRAL RAY
Direct central ray perpendicular to midpoint of forearm.
IMAGE CRITERIA
Proximal row of carpal bones and distal humerus should be included.
Humeral condyles should be in a parallel plane and not distorted.
Pelbow joint will be slightly opened (if entire upper extremity is in same plane).
slight superimposition of radial head, neck, and tuberosity over proximal ulna is generally seen.
Only a slight difference in density should be apparent between proximal and distal portions of forearm.

LATERAL PROJECTION FOR LATERAL FOREARM X RAY
ANATOMIC STRUCTURES
Entire radius and ulna
Proximal row of carpal bones
Elbow joint (including distal humerus)
FILM SIZE
11 X 14 in. (30 x 35 cm)
Divide film in hall lengthwise
PATIENT POSITION
Seat patient at end of table to place entire extremity in same horizontal plane as film
Place lead shield over patient to protect gonads.
PART POSITION
Flex elbow 90°
Align long axis of unmasked of cassette with long axis of forearm
Center unmasked 1/2 of cassette to mid portion of forearm.
Place hand in lateral position (thumb up).
CENTRAL RAY
Direct central ray perpendicular to mid portion of forearm.
IMAGE CRITERIA
Proximal row of carpal bones and distal humerus should be included
Elbow joint should be flexed 90″ so that epicondyles of humerus are superimposed
Radial head should overlap coronoid process of ulna.
Radial tuberosity is not apparent (if radius is in lateral position)
Distal ends of radius and ulna should be superimposed
Only a slight difference in density should be apparent between proximal and distal portions of forearm
