Aim: The supratrochlear foramen is an aperture or hole that is created when the bony septum between the olecranon fossa and coronoid fossa becomes perforated. The STF has achieved importance in recent years as its knowledge is useful for anatomists, anthropologists, orthopedic surgeons, and radiologists. The goal of our study was to determine the morphometric measurements of STFs in the AndhraPradesh population. Materials &Methods: The study was conducted on 135 humeri of unknown sex and age. The STFs were measured using Vernier calipers and the measurements on both the sides were tabulated & statistically analyzed. A light source was used to determine the translucency of the septum. Observations & Results: The prevalence of STF in the present study is 22.96% and is more common on the left side. Majority of STFs were oval (61.29%) followed by round apertures (32.25%). In the present study, the mean transverse diameter of the STF was 6.49mm and 6.35 mm, on left and right sides respectively while the vertical diameter was 4.88mm and 4.16mm on left and right sides respectively. Conclusion: STF is associated with narrow and shorter medullary canal and anterior angulation at the distal humerus. The knowledge of STF is very important for preoperative planning of intramedullary nailing for treatment of supracondylar fractures, especially following traumatic injuries and pathologic fracture.
