What is the required angulation for obtained coccyx radiographs in the average adult?

In obtaining coccyx radiographs, the required angulation is typically set at 10 degrees caudal. This specific angle is important because it helps to ensure the coccyx is positioned correctly within the imaging field, providing a clear view necessary for diagnosis. The caudal angulation aligns the x-ray beam to what is anatomically appropriate for visualizing the coccyx, which is recorded in the lower pelvic region. Proper angulation minimizes the distortion and superimposition of surrounding structures, improving the quality of the image and aiding in accurate assessments of potential fractures, dislocations, or other abnormalities. Thus, using a 10-degree caudal angle becomes essential in standard practice for imaging the coccyx effectively.
