More Book Details

Description of the Book:

The interosseous Membrane (IOM) is a fibrous structure located within the forearm that possesses distinct direction and shape patterns. The membrane maintains the interosseous space between the radius and ulna through forearm rotations and actively transfers forces from the radius to the ulna. The interosseous membrane’s load transferring ability reduces the forces placed on the radiocapitellar joint, thereby preventing radial head fracture. However, large chronic loading results in attenuation of the membrane fibers, thereby reducing longitudinal stability. We propose that the IOM functions similarly to a composite material composed of stiff central fibers (longitudinal portion) surrounded by a supporting fibrous matrix (transverse portion). A novel theoretical/experimental approach is taken to measure mechanical properties of the intact interrosseus membrane. This data will be necessary for modeling forearm stability in normal and pathologic conditions and analysis of repair procedures
