Introduction: Olecranon fossa and coronoid fossa of lower end of humerus are separated by a thin plate of bone called supratrochlear septum. In some cases this septum is perforated, named as supratrochlear foramen. Materials and Methods: The present study is carried out with 270 (119 left sided + 151 right sided) dried humeri of unknown sex and age. Bones were examined for the presence of supratrochlear foramen, their shape and measured vertical and horizontal diameters. Translucency of septum was identified by keeping the bone against a light source. Results: Observation of 270 humeri showed the presence of Supra trochlear foramen in 57(26%) bones. 26% left sided bones and 17.21% of right sided bones were found to have STF. Oval shaped foramen dominated the other shapes. The mean transverse diameter of foramen was observed to be 6.36 __ampersandsignplusmn; 2.88 mm on left side and 5.76 __ampersandsignplusmn; 2.22 mm on right side, where as the vertical diameter was found to be 4.76 __ampersandsignplusmn; 2.64 mm mm on left side and 4.64 __ampersandsignplusmn; 2.45 mm on right side. Out of 213 bones, transluscency of septum was observed in 130 (61.03%) humeri. Conclusion: The present study suggests left preponderance with majority of oval shape of supra trochlear foramen in similaritywith most other studies done in India. The knowledge of STF is important to Orthopedicians, radiologists and Anthropologists
