Abstract
Background: Sexual identification from the skeletal parts has medico legal and anthropological importance. The femur the longest and strongest bone in the skeleton.
 Objectives: to obtain values of maximum femoral length and to evaluate its possible usefulness in determining correct sexual identification.
 Material and Methods: Study sample consisted of 190 dry, normal, adult, human femora (140 male & 50 female) from skeletal collections of Anatomy department, Government Medical College, Datia. Maximum length of femur was considered as maximum vertical distance between upper end of head of femur and the lowest point on femoral condyle, measured with the osteometric board.
 Results: Mean Values obtained were, 450.81 and 416.48 for right male and female, and 443.35 and 419.44 for left male and female respectively. Higher value in male was statistically highly significant (P< 0.001) on both sides. Demarking point (D.P.) analysis of the data showed that right femora with maximum length more than 474.70 were male and less than 377.99 were female; while for left bones, femora with maximum length more than 484.49 were male and less than 385.73 were definitely female.
 Conclusion: Maximum length identified 13.43% of right male femora, 4.35% of right female femora, 7.25% of left male femora and 8% of left female femora
 Keywords: Maximum length, Sexual dimorphism, Femur, osteometry, femoral length.
Highlights
The femur the longest and strongest bone in the skeleton
Maximum length of femur was considered as maximum vertical distance between upper end of head of femur and the lowest point on femoral condyle, measured with the osteometric board
Maximum length was measured with Femur on Osteometric board in such a manner that medial condyle touches the short vertical wall; the moveable cross-piece should touch the highest point of the head
Summary
The femur the longest and strongest bone in the skeleton. It is almost perfectly cylindrical in the greater part of its extent. The determination of sex from skeletal remains is of very much medico legal and anthropological importance. Sex determination is relatively easy if the entire skeleton is available, pelvis and skull are the most reliable bones for this purpose.[2] in medicolegal cases one does not always have a complete pelvis or skull. Present study was carried out to ascertain sexual dimorphism of maximum femoral length in femora from datia region. Sexual identification from the skeletal parts has medico legal and anthropological importance. Objectives: to obtain values of maximum femoral length and to evaluate its possible usefulness in determining correct sexual identification. Conclusion: Maximum length identified 13.43% of right male femora, 4.35% of right female femora, 7.25% of left male femora and 8% of left female femora Keywords: Maximum length, Sexual dimorphism, Femur, osteometry, femoral length
