In the ideal setting the radial head would be replaced, taking care not to overstuff the radiocapitellar joint; however, this is frequently not the case as these patients often have had a previous radial head replacement that has failed and destroyed the capitellum. Kapandji A Biomechanics of pronation and supination of the forearm Hand Clin 17 1 — Biomechanics of the distal radioulnar joint. The interosseous membrane is designed to shift compressive loads as in doing a hand-stand from the distal radius to the proximal ulna. Morrey et al demonstrated these findings clinically. Stabilizers of the forearm exist proximally, centrally, and distally. If the capitellum has been severely compromised, radial head resection of the previously failed prosthesis may be all that can be done, recognizing that the reconstructed IOM will now bear more load. Some studies have been performed with an intact radial head, others with the radial head excised or with the elbow in varus, limiting radial head contact with the capitellum. The muscles are oriented obliquely from the ulna to the radius and load the distal radius through the hand-wrist unit.
The interosseous membrane of the forearm is a fibrous sheet that connects the interosseous The interosseus membrane divides the forearm into anterior and posterior compartments, serves as a site of attachment for muscles of the forearm, and transfers loads placed on the forearm.
The interosseous membrane is. Some forearm muscles attach to the interosseous membrane and it also separates the forearm muscles into anterior and posterior portions.
Interosseous Membrane of the Forearm
Understanding the anatomy of the IOM is possible only when the from the anterior and posterior interosseous nerves and arteries.
Had no idea my ulnas and radii had middlemen.

Without them our forearm bones might gnash together in high-strain activity. The interosseous membrane affects load distribution in the forearm. Wonder if other two-boned forearm-wielding creatures have them too?

The histology is similar to a tendon with a collagen arranged in an orderly manner with a surrounding elastin sheath. Support Center Support Center.
I have not had to salvage any of these patients to date with further procedures, including the ultimate salvage—a one-bone forearm.
