Introduction: The Supra trochlear aperture is situated on thin transparent bony plate which separates the Olecranon fossa and Coronoid fossa of the humerus. The Supra trochlear foramen (STF) is relatively common, seen in some humerii.
Materials and Methods: The current study was done in 108 dried humerii (right 45 and left 63) from the Anatomy Department, Kamineni Academy of Medical Sciences and Research Centre, Hyderabad, Gandhi Medical College, Secunderabad and Osmania Medical College, Hyderabad. The presence of STF, its different shapes and the vertical and transverse diameter were observed. In bones w here the foramen was not present, translucency and opacity of Supra trochlear septum were noted.
Results and Conclusion: The supra trochlear foramen was seen in 34 humerii (31.4%) and 74 humerii (68.5%) were without STF. Among 74 humerii, translucency Supra trochlear septum was seen in 23 (21.2%) and the rest opaque septum (normal) was seen in 51 humerii (47.2%). The supra trochlear aperture was more common on the left side about 23 in number (21.3%) than on the right side which was 11 in number ( 10.1%) . The different shapes like oval, round and triangular were also observed and most common shape is oval.
We attempted to enlighten the knowledge of presence of Supra trochlear foramen and translucent supra trochlear septum in the dry humerii. These bony features are important for anatomists, orthopedicians and radiologists in their routine practical knowledge and interpretation in their respective areas.
