Why is it important?
Background: Supratrochlear foramen (STF) islocated on the bony septum that separates theolecranon fossa from the coronoid fossa, at the lowerend of the humerus. The knowledge of the presence of STF in a humerus may be important for preoperativeplanning for treatment of supracondylar fracture.The presence of STF may also result in erroneous interpretation of radiographs. Materials and methods: The STF was studiedin detail in 300 (175 right side and 125 left side) human dried humeri of unknown sex and age. Thetopographical anatomy of the STF was studied in detail, morphometric measurements were taken, and the specimens were photographed. Results: Out of the 300 bones studied, 140 cases(46.6%) showed the presence of STF. The STF wasoval, round, and triangular in shape in 128, 7, and 5cases, respectively. The mean length of the transverse diameter for supratrochlear foramen was 6.60 mmand 5.9 mm on the left and right sides, respectively.The mean length of the vertical diameter for STF was4.80 mm and 3.80 mm on the left and right sides, respectively. Most of the bones that had no STFshowed a translucency of septum, in 54.4% of the bones. Conclusions: The results of our study show that STFis more common on the right side, with the oval shapebeing more common. The respective sides did notexhibit any statistical significant differences. Presence of STF may be important for anthropological, clinical, and academic purpose.
