Physical Fit Analysis in Forensic Anthropology: Its Role in Fragment Reassociation and Human Identification

Physical fit analysis has become an important complementary approach in forensic anthropology, particularly in cases involving fragmented human remains, where fragment reassociation is often critical to human identification. This review examines the role of physical fit analysis in fragment reassociation and its contribution to identification in forensic contexts, including disaster victim identification. To this end, the available literature was critically reviewed, with emphasis on physical fit, fracture matching, fracture morphology, and the interpretation of skeletal discontinuities in fragmented remains. The reviewed studies indicate that physical fit analysis can support the recognition of corresponding fragments, the reconstruction of disrupted skeletal regions, and the integration of anthropological findings with other identification methods, especially in cases involving highly fragmented or commingled remains. At the same time, the literature reveals important limitations, including methodological heterogeneity, limited validation studies, and interpretive challenges related to preservation and fracture complexity. Overall, physical fit analysis represents a promising adjunct in forensic anthropology for fragment reassociation and human identification, although further standardization and validation remain necessary to strengthen its forensic applicability.
