supracondylar foramen humerus
An olecranon foramen, also known as septal aperture or supratrochlear foramen, is a common normal anatomical variant of the distal humerus.
There is a wide variation of incidence, occurring between 5% to 50% of the population depending on ethnicity, being more common in individuals of African descent than Caucasians, and is most often bilateral .
The olecranon foramen is an aperture formed by the failure of ossification of the septum that separates the coronoid and olecranon fossae.
- presence may put patients at increased risk of distal humerus fractures
