The following case documentation illustrates the medical course of severe chronic polyarthritis and, subsequently, pseudarthrosis. The patient underwent RL screw arthrodesis to stabilize the wrist with preservation of partial mobility. Radiograph 1 year postoperatively shows significant pseudarthrosis. A second procedure involves the removal of the 2.4mm thick metal screws. After core drilling and tapping, two 3.5mm thick Shark Screw® grafts are inserted.
