Sternal foramen

Dr Henry Knipe et al.

Sternal foramen (or perforated sternum) is a developmental variant of the sternum and results from incomplete fusion of the sternal ossification centres. They are common occurring in approximately 5% of the population (range 4.3-6.7%). They are most commonly found in the inferior aspect of the sternal body

Small foramina can be mistaken for sternal fractures.
