What is abnormal union of the posterior talus and underlying calcaneous?

Answer 1

The talus and calcaneous ae bones in the heel. the calcaneus is the one you generally consider to be the heel bone and the talus is the one above it, which connects to the leg bones.

"posterior" makes no sense, because there are only two of each, one in each foot, and of course they're posterior. "Posterior" just means that the bones are toward the back of the body.

I'm assuming that an abnormal union of the bones, which to me means that one is mishapen or misplaced so they don't fit together right, would (a) make walking difficult, if not impossible, and (b) be painful since calcaneus takes all the weight of the body with each step.

Do you have this?

Answer 2

The talus and calcaneous are bones in the ankle and heel. Essentially it sounds like the heel bone and the bone in the foot which forms the ankle with the tibia and fibula have fused, joined into one bone. The calcaneus lies directly below the talus, and normally has a somewhat flexible joint with it. If the two bones fuse, you'll lose some motion in the part of your foot directly under the ankle.

There may be some pain involved, or it may simply be stiff but not painful. I can't answer as to whether there is any surgical technique which would free the union. That's a question for an orthopedic surgeon who specializes in the foot. You could also consult with a podiatrist, though I prefer an MD orthopedist.
