The baby has had minor complications, but the newest one is what was described as a sacral dimple. It is very small. The baby did have sepsis on and off for the first few weeks of life, and I have heard that UTI's can cause this sacral dimple.
Sacral dimples refer to the divots found on the lower backs of some infants.
During the first 8 weeks or so of development, the fetus develops the rudimentary structure of the spinal column called the neural tube. This tube forms sort of in the same manner as when the edges of a flat piece of paper are brought together to form a tube. But it gets a little more complicated. Now picture this tube forming from several sheets of paper that are placed on top of each other. To form a complete neural tube, all the edges of all the layers must meet to be complete.
