Interosseous membrane
Membrana interossea
Definition
The interosseous membrane is a broad, fibrous sheet of connective tissue that joins the shafts of two long bones, most notably the radius and ulna in the forearm (Interosseous membrane of forearm) and the tibia and fibula (Interosseous membrane of leg).
It is composed of both membranous and ligamentous regions, including distinct structures such as the central band, accessory bands, proximal interosseous band, and membranous portions.
