ANALYSIS OF DISTAL TRANSVERSE, PROXIMAL TRANSVERSE AND THENAR CREASE TYPES

Objective: Palmar creases, which develop during embryonic life, are clinically important for identifying potential chromosomal abnormalities. This paper investigated palmar creases' definition, variation, course, type, and class. Material and Methods: The sample comprised 753 right and left hands of 377 participants (222 females and 155 males). Participants were recruited from the Faculty of Medicine of Karadeniz Technical University. Their palmar creases were visualized and classified according to the type, location, and relationship with each other. Results: The distal transverse, proximal transverse, and thenar creases were predominantly of the forked type. When comparing the localization types of the proximal transverse and thenar creases on the radial side of the right and left hands by gender, the closed type was found to be the most common in both hands. Conclusion: This study focused on palmar creases. Our results provide clues for early detection of chromosomal aberrations. We think that we need to define palmar creases as a useful indicator during surgery.
