ANATOMY OF THE FOREARM

++
++

Bones

++

The bones of the forearm are the ulna and the radius (Figure 24–1). The ulna, which may be thought of as a direct extension of the humerus, is long, straight, and larger proximally than distally. The radius, considered an extension of the hand, is thicker distally than proximally.

Articulations

++

The forearm has three articulations: the superior, middle, and distal radioulnar joints. The superior radioulnar articulation is a pivot joint that moves in a ring formed by the ulna and the annular ligament.

++

The middle radioulnar joint, which is the junction between the shafts of the ulna and the radius, is held together by an oblique ligamentous cord and the interosseous membrane. The oblique cord is a small band of ligamentous fibers that are attached to the lateral side of the ulna and pass downward and laterally to the radius. The interosseous membrane is a thin sheet of fibrous tissue that runs downward between the radius and the ulna and transmits forces directly through the hand from the radius to the ulna. The middle radioulnar ...
