ABSTRACT
Background: Hip bone is the most sexually dimorphic bone in adult human skeleton, which provides sufficientevidence for sex determination even if fragmentary remains are available, and thus it is of great use both formedico-legal and archaeological purposes. Recent improved researches on metric assessment of variousparameters of hip bone are an effort to decrease ambiguity in assessment methods. Present study aims todetermine the sexual dimorphism in the morphometric parameters of ischial component of dry hip bone.Material and Methods: Present study was conducted on 100 undamaged hip bones, of known sex and unknownage (M:F=80:20, R:L= 50:50) procured from the Department of Anatomy, Government Medical College, Amritsar.The various dimensions measured were (1) Height of Ischium, (2) Length of Ischium upto the farthest point onacetabular rim, (3) Lower Spinal Height, (4) Front Spinal Height. The observations were statistically evaluated tofind out sex & side related differences.Results: All these parameters were significantly longer in males as compared to females. Also these were more onright side in both sexes but the difference was statistically insignificant.Conclusions: The results of the present study can be used for sex determination from the fragmentary remains ofhip bone. The study also advocates a need for more studies of similar parameters for other regional populationsto build up larger databases due to paucity of comparative data
