A pseudo-epiphysis is an epiphysis-looking end of a bone where an epiphysis is not normally located.
A pseudo-epiphysis is delineated by a transverse notch, looking similar to a growth plate.
However, these transverse notches lack the typical cell columns found in normal growth plates, and do not contribute significantly to longitudinal bone growth.
Pseudo-epiphyses are found at the distal end of the first metacarpal bone in 80% of the normal population, and at the proximal end of the second metacarpal in 60%.
