Placement of the umbilicus in an abdominoplasty

The location of the umbilicus was measured in 100 randomly selected non-obese subjects. It was found that a line drawn from the highest level of the crest of one ilium to the same point on the other side will transect the umbilicus in 96 percent of the subjects. This relationship can be of use during an abdominoplasty, when determining the location for the umbilicus.
