Bilateral scaphotrapezium-trapezoid coalition with bipartite scaphoid: case report.
We report on a 15-year-old girl with bilateral scaphotrapezium-trapezoid coalitions and bipartite scaphoids. There was no history of trauma or any other associated pathology. Wrist pain was alleviated by arthrodesis of the pseudarthrosis of the scaphoid component of the coalitions. Coalition of the distal portions of the scaphoids may have interfered with union of 2 ossification centers of the scaphoid. It is also possible that the carpal coalitions predisposed the scaphoid to fracture and that this represents bilateral nonunion.
