Diagnosis:

bipartite scaphoid



Discussion



Question : Bilateral scaphoid fracture  or Normal variation ?





Findings:


             Bilateral fragmentation of scaphoid


             Clear surrounding cortex


 



Diagnosis:  Bipartite scaphoid






Discussion:


 






Tröll (1926)



Cartilage surface between two fragments


 


 


Bipartite scaphoid does not arise from two centers of ossification as an anomaly of development, but only as the result of injuries


 

 

Piersol (1907)



True bipartite scaphoid does occur, though rarely


 


Jordan (1926)



Three possible methods


 


Persist enlarged sesamoid bone on the radial side of carpus


 


Persistence and progressive development of the primordium of an os centrale, a carpal bone of the manus of submammalian forms, represented by a discrete cartilage in human fetus, which normally disappears


 


Most probably, tow centers of ossification and failure of normal union


 

 

Faulkner DM (1928)


 


Bipartite scaphoid, with cartilaginous surface between the fragments, does occur


 


Abnormal joint maybe the seat of arthritis


 


Knowledge of this anomalous development of scaphoid is important to both radiologist and surgeon.
