The Ulnar Nerve: Bilateral Complete Congenital Dislocation

This represents an exceptionally rare presentation. I will refrain from statistical elaboration, but note it is the first such case I have encountered in my medical career. After thorough literature review, I found similar reported cases – but these were clearly acquired (as explicitly stated by their authors). Thus, the congenital origin and bilateral involvement constitute, in my opinion, its exceptional and unique nature.
