Central band reconstruction for the treatment of Essex-Lopresti injury : A novel technique using the brachioradialis tendon.

Longitudinal stability of the forearm is mainly provided by three structures: the radiocapitellar contact, which acts as the primary stabilizer, the central band of the interosseous ligamentous complex (IOLC) and the intact triangular fibrocartilage complex (TFCC). In an Essex-Lopresti lesion the forearm becomes fully destabilized, since all of these three components are injured. Fixation or replacement of the radial head with a metallic prosthesis along with repair of the TFCC and stabilization of the distal radioulnar joint (DRUJ) are well-established treatment goals. However the reconstruction of the central band of the IOLC remains to some extent controversial. The authors believe that the reconstruction of the central band, particularly in active patients, is crucial in order to restore normal load distribution through the forearm, thus ensuring both transverse and longitudinal stability. In this article, we present a case with an Essex-Lopresti lesion, which was effectively treated acutely with restoration of all three components of the injury (radial head prosthesis, DRUJ repair and reconstruction of the central band of the IOLC). A novel technique by rerouting the brachioradialis tendon is described in detail.
