CAMRT Radiography Practice Exam

In the Coyle method for imaging the trauma radial head, what is the required elbow flexion?

1. 45 degrees

2. 80 degrees

3. 90 degrees

4. 120 degrees

The correct answer is: 90 degrees

In the Coyle method, which is used for imaging the trauma radial head, the required elbow flexion is 90 degrees. This specific angle is crucial for obtaining the optimal view of the radial head, ensuring that it is visualized in the correct plane, which aids in the assessment of any potential fractures or dislocations. Elbow flexion at this angle minimizes superimposition of bony structures and enhances clarity in the image, allowing for better analysis of the joint and surrounding anatomical details. While other degrees of flexion could be used in different imaging techniques, 90 degrees is the standard for the Coyle method specifically, as it targets the area of interest effectively. This position helps radiographers capture a clear image that meets the diagnostic requirements for trauma to the radial head.
