A cystic subchondral bone defect without joint pathology is called an intraosseous ganglion. Most occur in the lower limb. In the wrist the scaphoid and lunate are most often involved. We report a case of an intraosseous ganglion within the triquetrum, treated by curettage and grafting with the pisiform that had been removed.
