Reconstructing the interosseous ligament: A technique using a single bundle synthetic tape.

Reconstruction of the interosseous membrane of the forearm has gained popularity over recent decades and several surgical techniques have been described to treat the longitudinal instability of the forearm after an Essex-Lopresti injury (ELI). We propose a synthetic reconstruction of the interosseous ligament (IOL) with double Arthrex FiberTape® and present data from cadaveric specimens used to test the reconstruction. After reconstruction, proximal migratory forces were applied to the radius to assess the radioulnar displacement at wrist level. Safety of the technique was also assessed by measuring the distance between the fixation system and the posterior interosseous nerve (PIN). These experiments provide preliminary biomechanical data to support further evaluation of this technique for potential clinical application.
