A sacral dimple refers to a natural indentation or pit in the skin located on the lower back, typically emerging at birth in certain infants. Often situated just above the crease between the buttocks, the majority of sacral dimples are innocuous and necessitate no medical intervention.
However, a sacral dimple can serve as an indicator of a potentially serious spinal issue in a newborn if the dimple is sizeable or positioned near a tuft of hair, a skin tag, an abnormal lump, or an area of discoloration. Under such circumstances, your child’s healthcare provider may recommend an imaging examination. If a spinal anomaly is detected, the course of treatment will hinge on the root cause of the issue.
