Supratrochlear Foramen Of The Humerus: Two Cases From The Hellenic Region Of Magnesia

The supratrochlear foramen (STF) of the distal part of the humerus bone presents a known anatomical skeletonvariation. On the other hand the cause for its appearance remains obscure. Its incidence is reported to be from0% up to 60% among the adults, depending of the population. Results. Our research on dry bone skeletal remainsdemonstrated a very low incidence of 0.8% in the Magnesia region of the central Greece. Conclusions. STFincidence presents a huge percentage interval depending on the region in study. Due to various interventionalprocedures performed in the distal part of the humerus clinicians should be aware of this rare anatomicalvariation.
