What to Know About Sacral Dimple in Newborn Babies

There are some very serious conditions that can be very detrimental to your baby’s overall health. The sacral dimple shouldn’t sound overly frightening and it typically isn’t. A small percentage of babies are actually born with his indentation, which is found on the lower back. Only 4% of newborns will develop this indentation and most of them will never experience complications. However, the sacral dimple can actually be a warning sign of an impending or current disease. Everything you need to know will be listed below for your consideration.


Recognizing the Sacral Dimple

Typically, you will not be the one to notice the dimple. During the post-natal checks, your pediatrician should spot and recognize the indentation. After they’ve spotted it, they will begin looking at the baby further. Is the problem associated with an illness? They’ll also inspect the dimple’s floor very closely, in order to ensure that it is completely enclosed with skin. If a little patch of hair is located, the doctor will typically relate this to a potentially more serious complication.

Remember that the positioning of the dimple is also vital! If it is located very low on the baby’s bottom, this is better! There are a number of potential illnesses that can create the dimple, although they’re very rare.

Sacral Dimple Causes

Truthfully, the sacral dimple is actually natural and originates, during birth. With this in mind, there are actually no recognizable causes, but it is possible to associate the dimple to other serious complications. Take note that it is extremely rare for this indentation to result in a problem, but it does occur. Below, you will find some of the complications, which are usually a cause for concern.

  • Tethered Cord Syndrome – As the name suggests, this particular ailment impacts the spinal cord. When tissue attaches itself to the spinal cord and limits its mobility and movement, you’re dealing with this ailment. Typically, this will result in the inability to control the bladder. The child’s legs will likely also be weak, numb and somewhat lifeless.
  • Spina Bifida – Usually, the child will be plagued with spina bifidia occulta, which normally results in no symptoms. It typically occurs, when the spine doesn’t fully close and encapsulate the spinal cord, while the cord remains inside of the spinal canal.

Typically, the sacral dimple is nothing to worry about, unless a skin tag, abnormal skin color or small path of hair forms near the site.


At the end of the day, the sacral dimple is something to spot and recognize, but this will usually be done, by the medical professional, before your newborn is able to leave the hospital. If the mark is found, you shouldn’t worry right away, because it typically results in no complications whatsoever. However, your doctor will be able to inspect it more closely and determine, whether or not it is a source of concern.
