Objective: The coronoid fossa and the olecranon fossa located the distal end of the humerus are separated by a thin bone septum. This septum may be translucent or opaque. In some cases this septum may become perforated and it is called supratrochlear foramen. The aim of this study is to describe the morphology of the supratrochlear foramen of the humerus.


Material and Methods: This study was conducted on 108 dry humeri (R: 56, L: 52) belonging to adults whose age, gender and racial properties are unknown. They were examined to determine the presence of supratrochlear foramen. The shapes of supratrochlear foramen were determined and their diameters were measured.


Results: Supratrochlear foramen was observed in 11 cases on the right side and 11 cases on the left side. On the right side, 5 of these foramens were detected to be round-shaped, 3 of these oval-shaped and 3 of these kidney-shaped, while on the left side, 6 of these were detected to be oval-shaped, and 5 of these round-shaped. Fifty seven of the 86 dry humeri with no supratrochlear foramen had a translucent septum (R: 30 L: 27), and 29 of the 86 dry humeri had an opaque septum (R: 15, L: 14).


Conclusion: It is apparent that supratrochlear foramen has been evaluated on bones in generally in the literature and there are differences in incidence rates. Due to the clinical significance of this formation, it is thought that studying on a wider population of living individuals using radiologic imaging methods will contribute to the literature. In addition, although there are different terms used to express this formation in the literature, it is thought that adopting the name which is commonly used as supratrochlear foramen, is most appropriate.
