- Abstract
Purpose Fingerprints of an individual are considered as mark of his/her identity. The identity of a person from fingerprints is based upon dermal ridges which have very large variations in the form of ridge characteristics. Though only few people have been reported for not having dermal ridges on their palmer and plantar surfaces, quite large number of population is reported with hand and foot deformities causing effect on dermal ridges also. Some of these deformities can be classified as syndactyly, polydactyly and polysyndactyly. In present work, cases of such deformities have been studied with respect to dermal ridges on distal phalanges of the fingers which are used for fingerprinting. Method Inked Fingerprints of affected fingers were obtained along with photographs of the hands with deformities. The pattern types, flow of ridges were recorded and relationship of these with deformity was attempted. Results Very interesting findings have been observed and have been reported in the paper, as commonness of ridge pattern or no pattern type of the ridges etc. It seems that there is a relationship between pattern type and type of deformity. Conclusion In spite of being brief study, it is hoped that it may lead to a study at larger scale to understand the dermal ridges configuration on hands with deformities. In the field of crime investigation when fingerprints having supernumerary finger are found at the crime scene, additional information about the culprit is available to draw the inferences.
