Interosseous Membrane

- Discussion:
     - almost completely bridges radius & ulna from proximal to distal R-U joint
     - acts as a hinge for rotation of radius about ulna;
     - fibers run distally in oblique direction from radius and ulna;
     - central portion thickened in 3.5 cm band;
     - forces are transmitted from hand to radius & in turn to ulna via diffuse attachment of membrane
