Attempts to separate congenital radioulnar synostosis and restore forearm rotation had been disappointing until a new mobilization technique was developed by Kanaya and colleagues using free vascularized fascio-fat graft interposition. This technique provides a functional rotation arc, but postoperative forearm motion is difficult to evaluate given the inaccuracies in determining the range of motion and rotational axis using conventional x-rays or computed tomography. This study represents an attempt to analyze in vivo three-dimensional motion of the forearm with radioulnar synostosis treated by Kanaya's operation using a markerless bone registration technique. Six patients with seven postoperative forearms (six with congenital and one with posttraumatic radioulnar synostosis) underwent 3D computed tomography with the forearm in neutral, fully pronated, and fully supinated positions. Range of motion according to this method was 30 AE 188, significantly smaller than the 82 AE 298 from manual examination. Improvements in range of motion were significantly greater in cases without dislocation of the radial head (46 AE 138) than in cases with dislocation (19 AE 108). Dislocation of the radial head was also significantly correlated with an abnormal axis of rotation of the forearm. ß

“…Previous models (Kasten 2002, Yasutomi 2002 generally omit this physical IOM behavior, solving it purely geometrically without wrapping or material constraints, which potentially limits the range of pathologies that can be simulated. For example, the pathological cases where the IOM might be the reason for limited range of motion or instability could only be simulated and potentially diagnosed with our proposed system.…”

The Interosseous Membrane (IOM) is a fibrous ligament bundle connecting the ulna and the radius. It is well known that the IOM allows transferring partial load from the radius to the ulna (Pfaeffle 2005). It also influences the kinematics of the radioulnar joint (Yasutomi 2002, Tarr 1984).Three-Dimensional (3D) computer-assisted methods for preoperative planning of osteotomy have been applied successfully on forearm pathologies (Fürnstahl 2010, Murase 2008, Vlachopoulos 2015). However, to the best of our knowledge, models and studies of the influence of the IOM during pro-supination are limited to a kinematics analysis of the system, either with actual bone geometry (Fürnstahl 2009) or without it (Kasten 2002). In this work, we present a physical simulation of the forearm pro-supination involving the IOM biomechanical properties, for providing insights on the influence of the IOM on the radioulnar motion. We demonstrate a preliminary validation using a sample simulation performed on a healthy forearm by comparing its outcome with literature, and analyze the kinetic data that our method allows.
