Osseous Scaphotrapezial Coalition

الملخص EN

Osseous scaphotrapezial coalition is one of the rarest forms of carpal coalition of the hand.

Often discovered incidentally, pain and functional limitation have not been reported.

Carpal coalitions occurring across the carpal rows are thought to occur as a result of some insult or congenital anomaly.

Isolated scaphotrapezial coalition calls into question the traditional thinking that fusion between the proximal and distal carpal rows must be acquired or associated with congenital syndromes.
