This joint allows you to pronate and supinate (rotate) your forearm and hand. (eorthopod.com)
The head of the radius also articulates with the humerus at the capitellum, allowing the forearm to pronate and supinate. (orthopaedia.com)

The injury can also result from a direct blow to the forearm with the elbow extended and the forearm in hyper pronation [6] . (physio-pedia.com)
Isolated midshaft ulna (nightstick) fractures are often caused by a direct blow to the forearm. (aafp.org)
In adults, simultaneous fractures of the shaft of the ulna and radius (the so-called 'both bone fractures') are most often the consequence of a direct blow to the forearm or other high energy mechanisms. (orthopaedia.com)
