Abstract
To introduce a ligament in the posterior distal extent of the forearm interosseous membrane (IOM). Ten cadavers were dissected in which the ligament was consistently present extending obliquely from the distal radius metaphysis to the distal radioulnar joint capsule. The ligament was also explored in a patient during posterior interosseous nerve (PIN) excision. The posterior oblique ligament (POL) is found consistently in all cadavers via a dorsal approach. This discovery highlights the complexity of forearm ligamentous structures and their role in the proximal, middle, and distal radio-ulnar stabilization.
