The supratrochlear foramen. Clinical and anthropological considerations

Abstract

1. 1. The supratrochlear foramen should be looked for in the roentgenogram and noted, not only because of its clinical but also because of its anthropological interest. 2. 2. It is not found before the age of six years and is usually bilateral. 3. 3. It is more common in the female and is usually more characteristic and larger on the left sde. 4. 4. It is an anatomical variation and must not be misinterpreted in injuries to the elbow. 5. 5. An increase in hyperextension was found in association with a bilateral supratrochlear foramen in a child. 6. 6. A spherical ossicle is described, probably the sesamoid cubiti of Pfitzner, which has been pressed into the foramen by the overlying structures.
