Proximal Forearm – PA Projection
Acute Flexion
Image receptor 8 X 10 inch
Patient Position
Let patient seat at the end of the radiographic table with the elbow fully flexed.
Part Position Proximal Forearm
- Center the flexed elbow joint to the center of the image receptor. The long axis of the superimposed forearm and arm should be parallel with the long axis of the image receptor.
- Move the image receptor toward the shoulder so that the CR will pass to the mid point of the elbow.
- Shield gonads.
Central Ray:
The central ray is perpendicular to the flexed forearm, entering approximately 2 inches distal to the olecranon process.
Structure Shown Proximal Forearm
The superimposed bone of the arm and forearm are demonstrated. The elbow joint should be more open than for projection of the distal humerus.
Evaluation Criteria
The following should be clearly demonstrated:
- Forearm and humerus are superimposed.
- No rotation of the proximal forearm.
- The proximal radius and ulna are demonstrated.
