Here I 🎁 present: Blanka Schaumann & Milton Alter, “Dermatoglyphics in Medical Disorders”, 1976.
INTRODUCTION
In the mid-1970’s hand ✋and footprint 👣 were used in correspondence with cytogenetics of chromosome aberrations. Trisomy 21, 18 & 13 (Down, Edward & Patau) all showed dermatoglyphics patterns useful in an era of low-resolution karyotypes.
Blanka Schaumann & Milton Alter, “Dermatoglyphics in Medical Disorders“, 1976 is a representative textbook from the era of low-resolution karyotypes. The “Table of Contents” of the 📖 book is shown BELOW.
Table of Contents.
1. Embryogenesis and Genetics of Epidermal Ridges.
2. Methods of Recording Dermatoglyphics.
STANDARD METHODS.
Ink Methods Inkless Methods Transparent Adhesive Tape Method Photographic Method.
SPECIAL METHODS.

3. Dermatoglyphic Pattern Configurations.
RIDGE DETAIL (MINUTIAE) PATTERN CONFIGURATIONS.
Fingers (Fingertip pattern configurations, Dermatoglyphic landmarks, Patterns of middle and proximal phalanges) Palms (Palmar pattern configurations, Palmar landmarks) Toes Soles (Plantar pattern configurations, Plantar landmarks).
QUANTITATIVE ANALYSIS.
Pattern Intensity Ridge Counting (Finger and toe ridge counts, Ridge counts of digital areas, Ridge counting in patterns lacking triradii, Estimation of the ridge count on missing or mutilated finger-tips) Position of Axial Triradius (atd angle, Measurement of distal deviation, Ridge counting, Breadth ratio) Main-line Index
