AP wrist view with comparative normal study (left) and trapezoid dislocation (right).
The circle indicated the dislocated trapezoid bone in the distal carpal row.
Case Discussion
Carpal bone dislocation is uncommon. Orthogonal views are essential in identifying carpal bone injuries.
Close assessment of the alignment of the carpal rows will reduce the chance of missing this important injury.
