Introduction: The stature of an individual, one of the key elements of identification, can be calculated from the length of long bones in the body, of which the femur has the highest correlation with stature. Many a times, forensic anthropologists have to identify unknown dead bodies from fragments of bones that are available. Studies have proven that the total length of a bone can be estimated from fragments using population-specific regression equations. In the present study, the objective was to estimate the total length of the femur (TFL), in an Indian population, from measurements of its distal segment, using regression equations. Material and Methods: One hundred and twenty-one intact adult femurs were studied. The TFL and four variables from its distal segment were measured. Linear regression analysis was performed, and regression equations were derived to calculate the TFL from each of the variables. Results: The mean TFL was 41.9 ± 3.4 cm. All the four parameters of the distal segment showed a significant positive correlation with the total femoral length (P < 0.001), and of these, the width measured between the two epicondyles showed the maximum correlation. Multivariate and univariate regression equations were derived to estimate the TFL from these variables. Discussion and Conclusion: The TFL can be reliably calculated from the measurements of the distal fragments. These measurements can be used by forensic anthropologists for the estimation of the stature of an unknown individual.

Context: The obturator artery (OA) originates from the internal iliac artery (IIA), and it runs on the lateral pelvic wall to leave through the obturator canal. It can have a varied source of origin. A small pelvic space makes it susceptible to injury during repair of femoral and inguinal hernias and pelvic surgeries. Unexpected injury of an aberrant OA can be avoided only with a thorough knowledge of its anatomy. Aim: This study aims to estimate the prevalence and describe the course of aberrant obturator arteries. Settings and Design: A descriptive, cross-sectional, cadaveric study was conducted in the Department of Anatomy, Government Medical College, Thiruvananthapuram, India. Materials and Methods: Sixty-four hemipelvices were dissected. Variations in the origin, course, and relations of the OA were observed and noted. Statistical Analysis Used: The results were tabulated, and the prevalence of each variation was calculated. Results: Variations were seen in 40.6% cases. OA originated from inferior epigastric artery (23.4%), external iliac artery (3.1%), posterior division of IIA and iliolumbar artery (1.5%), superior gluteal artery (6.2%), internal pudendal artery (1.5%), and inferior gluteal artery (3.1%) cases. Arterial corona mortis, a tortuous anastomotic channel connecting OA (originating from IIA) and inferior epigastric artery was seen along with venous connections in one specimen. Conclusions: Aberrant origins of OA pose a high risk for significant hemorrhage in trauma and various surgeries. Hence, a sound anatomical knowledge of its origin and course is vital while repairing fractures and hernias in this region.
