Reconstruction of the distal oblique bundle of the interosseous membrane with extensor carpi radialis hemitendon: a new minimally-invasive technique

Abstract

The main stabilizing element of the distal radioulnar joint (DRUJ) is the triangular fibrocartilage complex (TFCC). Secondary stabilizers include the distal oblique band (DOB), which is inconsistently found. When TFCC repair has failed or cannot be performed, DOB reconstruction is a therapeutic option. Even though distal radioulnar ligamentoplasty remains the technique of choice, recent papers show similar outcomes from both methods. We present two cases of successful DOB repair with the extensor carpi radialis longus (ECRL) hemitendon.
