Context: Olecranon fossa in humerus may be perforated. The perforated olecranon fossa, in general is reported associated to the left humerus and humerus of the female sex. Aims: In the present study, it is aimed to find out the occurrence of the perforated olecranon fossa in the humerus. Settings and Designs: Department of Anatomy, International Medical School, Bangalore. Methods and Materials: 44 humerus were available in the institute; out of which, 22 each belonged to the right and left sides. The subjective sex determination could identify 24 as male and 20 as the female humerus. Statistical Analysis: The percentage analysis was done. Results: The perforated olecranon fossa was observed in 17 (38.6%) humerus. Their presence was found to be associated to the left (50%) and the female (50%) humerus. Conclusion: The finding could be of significance, academically for the anatomists and anthropologists and clinically for the radiologists and orthopedic surgeons for the transhumoral approach for the elbow arthroscopy.
