Fig. 3From: Arthroscopic-assisted radiocarpal ligaments tensioning for dynamic radiocarpal instabilitySchematic diagram showing the steps of arthroscopic procedures. a Perform thermal shrinkage for the radioscaphocapitate (RSC) (black arrow) and long radiolunate (LRL) (white arrow) ligaments from 3 to 4 (or 1–2) portal. b Inset a switch stick into the interval between the RSC and LRL ligaments and forward it volarly to come out of the volar wrist skin. c Set the arthroscope sheath onto the switch stick from the volar side and forward it dorsally to come out of the dorsal wrist skin. d Removal of the switch stick and subsequently set the vessel loop through the canal of the arthroscopic sheathBack to article page
