Introduction: The distal end of the femur is a highly vascular tissue with unique features in its blood supply. The outcome of surgical interventions is determined by the interference of corresponding blood supply. The study examines the pattern of blood supply in terms of density, size, and direction of vascular foramina (VF) to the distal end. Material and Methods: The lower end of normal adult dry femora (n = 300) was divided into segments. The number, size, and direction of VF in each segment were documented. Wilcoxon signed-rank test identified the statistical difference in the number of VF between various segments and Friedman test compared the difference between segments of two sides. Results: The maximum average number of VF was observed in medial condylar surface while minimum in central part of intercondylar region. Condylar medial recorded the highest number of VF of all sizes. The number of VF of >2 mm size was found to be significantly different between right and left in right condylar lateral and right intercondylar posterior regions. Right condylar lateral had considerably large number of VF of >2 mm size with statistical significance (P = 0.000). A Friedman test indicated that segements of two sides rated differently. Discussion and Conclusion: The density of VF through which vessels traverse at lower end were not only numerous but also constant and uniformly scattered. Detailed understanding of the arterial anatomy of lower end helps to identify and localize vascular pedicles, thus ensuring vitality of graft as well as donor site.
