Study Notes
- The interosseous membrane binds the radius and ulna together in the forearm.
- The central band is the prominent fiber of the interosseous membrane.
- The central band is nearly twice as thick as other fibers and has a high tensile strength.
- Two smaller components of the interosseous membrane are described, including the oblique cord at the proximal forearm and the distal oblique fibers at the extreme distal aspect of the forearm.
- The functional significance of the oblique cord is in question, but it may help limit distal migration of the radius relative to the ulna.
- The distal oblique fibers are present in about 40% of membranes and add to the stability of the distal radio-ulnar joint.
- The distal oblique fibers flow in an irregular fashion, but are generally directed distal-laterally from the distal one-sixth of the ulnar shaft to the extreme distal radius.
- The distal oblique fibers are located directly deep to the pronator quadratus muscle.
- The interosseous membrane has been studied extensively in cadavers.
- The interosseous membrane is an important structure for the stability and function of the forearm.
