3D CT scan showing partial coccygectomy: one bone left behind. Coccyx pain. Tailbone pain

(See the video down below if you prefer to watch this as a video.)

  • This is a short video showing a CT scan, or computerized tomography scan.
  • A CT scan, or CAT scan, of the pelvis, particularly focusing on the sacrum and coccyx, in a patient who underwent a coccygectomy. And the first coccygeal bone (which is this bone right here) was essentially left behind.
  • So it’s a “partial” coccygectomy, rather than a complete coccygectomy.
  • I’m Dr. Patrick Foye. I’m the Director of the Coccyx Pain Center, online at www.TailboneDoctor.com.
  • In this short video, we’re going to review this.
  • The reason why we know that this is indeed the first coccygeal bone is from looking at the anatomy.
  • In my book, I have a whole chapter on anatomy.
  • I’m holding the camera with one hand, so I’m trying to show you with the other hand.
  • In the chapter on anatomy, if you look here, you can see that the first coccygeal bone has these two areas.
  • These two areas come up—they call them horns or cornua—that extend upward from the top of the coccyx.
  • Those meet the sacral cornua, which project downward.
  • From the side view, we can see that the cornua hook up like that.
  • Coming back to our CT scan here, you can see those cornua right here, coming upwards from that remaining coccygeal bone.
  • If I swing around, you can see them very nicely here again—this one and this one—projecting upwards.
  • Those are signs that this is indeed the first coccygeal bone.
  • The coccygeal cornua, or horns, are projecting upward to meet the sacral cornua, which are projecting downward.
  • This is where the first coccygeal bone was left behind.
  • I’ll show you that in one other spot here on an anatomic model of the coccyx.
  • Again, you can see those horns or cornua heading upward, just as we see here.
  • That is indeed the first coccygeal bone still remaining in this patient who underwent a coccygectomy.
  • Unfortunately, there are many times where patients are told that they are having a complete coccygectomy, but sometimes the first coccygeal bone or other coccygeal bones may be accidentally or inadvertently left behind.
  • Then, we need to decide whether they should have been removed.
  • Most people do not need coccygectomy surgery for their tailbone pain.
  • But for those who do, it needs to be a conscious decision made between the patient and the surgeon about whether to do a total versus a partial coccygectomy.
  • If the decision is to do a total coccygectomy, then you want to make sure that the entire tailbone is removed and that a piece of it is not accidentally left behind.
  • I just wanted to point that out since this is a good image for showing that.
  • That’s all for now.
  • I hope this has been helpful in distinguishing partial versus complete coccygectomy.
  • For more information, you can find lots of details in my book, Tailbone Pain Relief Now, which you can get online at Amazon.
  • I hope this info is helpful for you.
