Oblique cord
Oblique cord (pronounced: oh-BLEEK kord) is a small, oblique ligament in the forearm. It is also known as the cord of Winslow or interosseous oblique ligament.
Etymology
The term "oblique cord" is derived from the Latin obliquus, meaning "slanting", and the Old French corde, meaning "string or rope". The term "cord of Winslow" is named after the British anatomist, Jacob Winslow (1669-1760), who first described it.
Anatomy
The oblique cord is a small, flattened band, extending downwards and medially, from the lateral side of the ulna near the base of the coronoid process, to the radius a little below the radial tuberosity. It is only distinct when the arm is fully supinated, and is sometimes wanting.
Function
The oblique cord serves to maintain the relative positions of the radius and ulna in the forearm. It also helps to prevent excessive supination or pronation of the forearm.
