This article discusses radiographic positioning for Radiologic Technologists (X-Ray Techs) to show the forearm and elbow. Forearm AP Purpose and Structures Shown This view should demonstrate the radius and ulna and soft tissue of the forearm.
Forearm x-rays are indicated for a variety of settings including: Where patients are in a considerable amount of pain, these two projections may replace the standard projections instead to obtain diagnostic images of the radius and ulna whilst requiring little to no patient movement.
The elbow internal oblique view is a specialized projection, utilized to demonstrate both the coronoid process in profile and the olecranon process sitting within the olecranon fossa of the humerus. The affected limb is pronated.
Ideally, upper arm, elbow, and forearm are all resting on the table. Position of part: Extend the arm straight out on the the table and rotate the arm internally. Place the posterior of the thumb on the the image receptor with the thumbnail down.
The forearm AP view is one of two standard projections in the forearm series to assess the radius and ulna. This view demonstrates the elbow joint in its natural anatomical position allowing for assessment of suspected dislocations or fractures and localizing foreign bodies within the forearm.
For posterior obliques (RPO and LPO), the posterior aspect of the patient’s shoulder is placed against the Bucky and the body angled 45 degrees with the grid. The anterior oblique position relates less radiation dose to the thyroid gland and better accommodates the diverging x-ray beam with the cervical lordosis.
Pronation of the hand crosses the radius over the ulna at its proximal third and rotates the humerus medially, resulting in an oblique projection of the forearm. The central ray (CR) should be perpendicular to the midpoint of the forearm.
Ideally, upper arm, elbow, and forearm are all resting on the table. Position of part: Rest the surface of the wrist over the image receptor. For a lateral rotation oblique, from a prone position, rotate the wrist laterally approximately 45 degrees.
Seat the patient at the end of the radiographic table. Have the patient rest the forearm on the table in the supine position. Place the image receptor under the wrist and center it at the dorsal surface of the wrist. Rotate the wrist medially (internally) until it forms a semisupinated position of approximately 45 degrees to the IR. Shield gonads.
We speculated that pronating the forearm when obtaining a radiograph may affect the displacement of the fracture, through either increased tension through the anatomic structures that insert ...
