Anatomic Interosseus Membrane Reconstruction Utilizing the Biceps Button and Screw Tenodesis for Essex-Lopresti Injuries.

Longitudinal radioulnar dissociation, also known as the Essex-Lopresti lesion, is a potentially debilitating condition causing painful instability of the forearm that often results from high-injury trauma with compromise of the proximal radius, triangular fibrocartilage complex, and the interosseous membrane. Indications for reconstruction of the interosseous membrane primarily include chronic instability of the forearm. Our reconstructive technique utilizes an anatomic allograft reconstruction with intraosseous fixation, in an effort to biologically reconstruct and anatomically tension the central band of the interosseus membrane.
