Revealing hand lines: the Sydney line & the simian crease!

May 3, 2009

The Sydney line: a.k.a. an extended 'head line' or 'proximal palmar transverse crease'.

No less than exactly 40 years ago articles in the famous Time Magazine and the Lancet revealed that certain characteristics in the hand lines can signal major medical problems. A few hand facts from 1969!

The patterns of the fingerprints and the palmar lines are established by the fourth fetal month of life in the womb, when the fetus’ hand is only a few millimeters long. The more conspicuous “flexion creases” (the palmist’s “heart, head and life lines”) are formed a month or two earlier.

In normal palms, the heart and head lines are separate and distinct, and neither extends clear across the palm. However, in many victims of Down’s syndrome, prenatal rubella, childhood leukemia, and even in Alzheimer dementia, the palmar lines are replaced by a Sydney line (see picture above), or a single “simian crease” (see picture below) – characteristics which are quite normal like that on a monkey’s palm!
