Fig. 2From: Arthroscopic triangular fibrocartilage complex reconstruction with free tendon graft for chronic distal radioulnar joint instabilityFovea preparation and ulnar tunnel creation. A The fovea region of the distal ulna was identified under arthroscopy. B The microvector drill guide was used to create an ulnar tunnel for anatomic insertion of the tendon graft. C The direction of pin could be confirmed by the fluoroscopy. D The intraarticular exit of the tunnel was confirmed through the fovea under arthroscopyBack to article page
