Abstract
Introduction: Th e pelvis is most sexually dimorphic and is the fi rst bone assessed in sex determination because it is the skeletal
element most aff ected by reproduction and parturition.1 Th e assessment of the pelvis is made through metric measurements as well
as through the visual analysis of non-metric traits; both important aspects of the analysis. Th e best methods for determining sex
from adult skeletal remains involve measurement and inspection of the hip bone that presents a number of gender-related anatomical
diff erences.2 Most osteologists visually (stereoscopic) evaluate these diff erences and integrate this subjective assessment ofhip
bonemorphology into their sex determinations. Th e aim of thepresent study is to visually evaluate sexual diff erences in hip bone and
comparing its effi cacy with metric assessment. Methods: Th is study is done on 46 hip bones of adult individuals of known sex from
museum of department of anatomy of SGRRIM&HS Dehradun and TMMC&RC Moradabad, India. All these hip bones were visually
examined and under mentioned fi ve characters of the hip bone were used, (A) aspects of the preauricular surface, (B) aspects of the
greater sciatic notch, (C) the form of the composite arch, (D) the morphology of the inferior pelvis, and (E) ischiopubic proportions.
Results: In this study traits of the group (A) were most sexually dimorphic while traits of the group (E) were least sexually dimorphic.
Conclusion: Diagnostic accuracy is excellent when the complete hip bone is available. Hip bone features used for sex determination
by visual assessment seem to be fairly stable.
