Bilateral bipartite carpal scaphoid: a case report and literature review.

Congenital bipartite carpal scaphoid has been reported as an extremely rare congenital anomaly. We report a case of a 47-year-old man who was found with bilateral bipartite carpal scaphoids with no history of injury. Radiographs demonstrated symmetric findings of the distinct bipartition of the scaphoid without obvious degenerative change in both wrists. The patient complained of no other symptoms. The diagnostic differentiation of scaphoid bipartition from the pseudarthrosis of the scaphoid could be important in avoiding unnecessary surgery and inappropriate assessment in compensation cases.
