BACKGROUND: Studies have suggested that identification of
aberrant palmar creases may give clues for an early and non-
invasive method of diagnosis of certain disease conditions. Toward
this purpose, awareness of the normal variants of palmar creases
must be first recognized. Accordingly, this study aimed to investigate
the patterns of palmar creases in healthy Ethiopian population
among Medical and Dental Students in Addis Ababa.
SUBJECTS AND METHODS: Right and left palm pictures from
318 (177 females and 141 males) participants were taken using a
mobile camera, and evaluated qualitatively. Observations were
analyzed by Fisher's exact test, and significance levels for
comparisons were set at p<0.05.
RESULTS: Aberrant creases were observed in 13.8% of the palms.
Simian crease was the most common among the aberrant crease
types, followed by Suwon and Sydney. Palmar creases with two and
three points of origin were significantly more common, respectively,
in males and the females. Minor variants as accessory to the radial
longitudinal crease and middle longitudinal crease were also
CONCLUSION: This study suggests that aberrant crease types at
the observed frequencies may not be indicative of known disease
conditions as they occurred in apparently healthy Ethiopians.
However, the results of this study, besides revealing the patterns of
palmar creases among Ethiopians, could give a baseline for studies
aimed at diagnosis of disease conditions based on palmar crease
configurations. Further qualitative and quantitative studies of
palmar creases in wider populations with various conditions,
including ethno-geographic factors, are recommended.
