Abstract: Aim: To evaluate sexual differences using demarking points and index of sexual dimorphism of the Breadth of the talus in relation to age of males and females in north eastern Nigerians. Methodology: Three hundred and twelve (312) radiographs of adult north eastern Nigerians (156 males and 156 females) with age ranged 20 to 69 years were measured retrospectively. Radiographs used for this study were obtained from the collection of the records unit of the Radiology Department, University of Maiduguri Teaching Hospital (UMTH) in Borno State, Nigeria. Both female and male samples were grouped into two separate subsamples (right and left talus). Samples were classified separately into five (5) age groups spanned ten years’ interval. Plain antero-posterior radiographs of the ankle were used for this study. Transverse Breadth (TB) of the talus was measured as a linear distance between the most medial and lateral points on the body of talus with a meter rule in centimeters (cm). Results: The result showed age related variation, with male TB of the talus ranging from 4.41cm at 60-69 years age group to 4.68 cm at 30-39 years age group; while the female TB of the talus ranged from 3.96 cm at 60-69 years age group to 4.19 cm at 30-39 years’ age group. The means of TB of talus for males are all significantly greater than their female counterparts of the same age group. The results also show statistically significant (p<0.001) differences between the Breadth of talus in males and females with the values of demarking points (DP) in males higher than those in the females. Parameters of index of sexual dimorphism (ISD) are greater than 100 which suggest that males have higher value over their female counterparts. Conclusion: It was observed that the TBs of talus are sexually dimorphic; the DPs of male parameters are all higher than those of their female Counterparts. ISD also shows that, male TBs are greater than those of the female counterparts: because the ISDs were all greater than 100 at all age groups. However, more studies are required in other part of Nigeria, so as to capture the racial variation in the country.
