Why This Test Might Be Ordered
Your healthcare provider may recommend a coccygeal X-ray if you’ve experienced pain, trauma, or symptoms like difficulty sitting, numbness, or tingling in the lower back or buttocks. It could also be part of an evaluation for conditions like sacroiliitis, coccygodynia, or suspected fractures.
What to Expect Before the Test
No special preparation is needed. You’ll lie on your back or side, and the technician will position your tailbone area to capture the clearest image. You may wear your usual clothing, but some facilities provide a gown. The procedure is quick and painless.
During the Test
You’ll be asked to hold still for a few seconds while the X-ray machine takes the image. The technician will adjust your position to ensure the best view of your coccyx. You won’t feel any discomfort, but you may hear a clicking sound as the X-ray machine moves.
After the Test
You can return to your normal activities immediately. The X-ray images will be reviewed by a radiologist, and your doctor will discuss the results with you. If you have concerns, ask your provider how to interpret the findings.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Coccygeal X-rays are primarily used to diagnose structural issues like fractures, dislocations, or degenerative changes. They may also help identify underlying conditions such as infections, tumors, or congenital abnormalities. Results guide treatment plans, which could include physical therapy, pain management, or surgical intervention if needed.
