l  Bipartite scaphoid has been debated,
and is of a traumatic origin for some authors and congenital for others

l  Supportive of the diagnosis of
congenital bipartite scaphoid

•       the absence of history of trauma

•       the presence of bilateral scaphoid

•       equal size and density of the both
ossicles

•       the absence of degenerative changes
I the radial scaphoid carpal articulation

•       clear space with smooth edges
between the  components
