Convexity of radius

Not to be confused with Radius of convexity a mathematical term.


Bones of the Forearm. Left: Anterior view, Right: Posterior view.

The Convexity of the radius or the convexity of the lateral surface of the radius refers to the lateral border of the radius bone (which curves outwards to be convex lateralward).

The Pronator teres muscle is described as attaching (distally) to the "middle of convexity of lateral surface of radius".^[1] It does this just below the insertion of the Supinator muscle.
