Understanding differences in the characteristics of human phalanxes is important for varied disciplines including anthropology, forensics, and surgery. For the most part, analysis of the phalanxes has been limited to “traditional” morphometric measurements such as length. Therefore, this preliminary study sought to utilize geometric morphometric methods in the analysis of phalanxes. After exclusions, a total of 1830 phalanxes (618 proximal, 610 middle, and 602 distal) from digits 2–4 were analyzed from PA radiographs. A set of four landmark points were applied to each phalanx. Canonical variate analysis (CVA) was performed among phalanx rows (i.e., proximal, middle, and distal). Additionally, CVA was utilized to identify shape variance of phalanxes, within‐row, according to digit number (i.e., 2 nd , 3 rd , 4 th , 5 th phalanxes within a given row). The results of this research suggest that geometric morphometric analysis of phalanxes may aid in the differentiation and identification of phalanxes.
