ABSTRACT
As the importance of the foveal attachment of the triangular fibrocartilage complex (TFCC) on the stability of the distal radioulnar joint (DRUJ) is emphasized, the traditional repair techniques such as arthroscopic capsular repair for the 1B TFCC tear become accepted as ineffective method for treating DRUJ instability. Recently, several techniques which repair the TFCC directly to the ulnar fovea have been developed and introduced. Further advances of the techniques will be expected with increasing knowledge of the anatomy and biomechanics of the TFCC and DRUJ. Regardless of the techniques, fundamental principle of anatomical repair of the TFCC to the ulnar fovea is utmost important. Herein we present our technique of arthroscopic transosseous repair by making a drill hole in the ulnar and securing the sutures with Pushlock anchors.
