Improved analysis of palm creases

Abstract

Palm creases are helpful in revealing anthropologic characteristics and diagnosing chromosomal aberrations, and have been analyzed qualitatively and quantitatively. However, previous methods of analyzing palm creases were not objective so that reproducibility could not be guaranteed. In this study, a more objective morphologic analysis of palm creases was developed. The features of the improved methods include the strict definition of major and minor palm creases and the systematic classification of major palm creases based on their relationships, branches, and variants. Furthermore, based on the analysis of 3,216 Koreans, palm creases were anthropologically interpreted. There was a tendency for palm creases to be evenly distributed on the palm, which was acknowledged by the relationship between major and minor creases as well as by the incidences of major creases types. This tendency was consistent with the role of palm creases to facilitate folding of palm skin. The union of major palm creases was frequent in males and right palms to have powerful hand grip. The new method of analyzing palm creases is expected to be widely used for anthropologic investigation and chromosomal diagnosis.

Prevalences of Simian, Sydney and Suwon Creases and their Association with Each Other, Body Sides, Handedness, Sex and Anomalies/Diseases/Syndromes in a Population of Central India

“…Total 1000 central Indian subjects (500 males and 500 females) aged between 5 to 70 years were randomly selected and examined by authors on both sides for the presence of the Simian, Sydney and Suwon creases with the help of method presented by Park et al (2010) (Figures 2 and 3). Subjects whose father or mother was not of central Indian ethnic origin or with injury of hands were excluded from study.…”

The Enigma of Simian Crease: Case series with literature review

“…[2][3][4]10,13 In our study, the doctor has SC on the both palms and is normal according to the various studies. 13 Palm creases have additional features that might indicate the possibility of chromosomal aberrations.…”

“…2,3,10 Males are twice more common than females to have this characteristic, and it tends to run in families. 13 It is frequently seen among Asians and Native Americans than among other populations, and in some families there is a tendency to inherit the condition unilaterally.

Gambaran Garis Telapak Tangan pada Siswa SD Negeri 144 Talang Betutu, Palembang, Sumatera Selatan

“…Distribusi pola garis STPC pada orang normal di Kota Palembang, Indonesia, tampaknya lebih banyak daripada orang Nigeria yang normal berdasarkan hasil penelitian Adetona dkk., 6 yaitu sebesar 0,5% pada tangan kanan dan 0,2% pada tangan kiri dan hasi penelitian di Korea bahwa garis Simian ditemukan sebesar 6,5%. 7 Sebuah studi yang dilakukan pada populasi India mendapatkan prevalensi garis Simian sebesar 14,4%. Garis STPC lebih dominan terdapat di tangan kanan serta berhubungan dengan jenis kelamin lakilaki.…”

“…5 yang menemukan distribusi garis Sydney sebanyak 1,5% pada tangan kanan dan 1,1% pada tangan kiri serta penelitian di Korea sebesar 1,2%. 7 Sebuah studi pada populasi India mendapatkan prevalensi garis Sydney sebesar 3,6%. 7 Garis Sydney pada penelitian ini ditemukan berimbang antara lakilaki dan perempuan (rasio 1:1).…”
