Physical Simulation of the Interosseous Ligaments During Forearm Rotation

8 pagesPublished: June 13, 2017


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.
