Then the Pronator quadratus muscle is found and detached from the radius.
2.
Why the contraction of pronator quadratus produces pronation, and not supination?
3.
It is assisted in this action by pronator quadratus.
4.
In the forearm, this action is performed by pronator quadratus and pronator teres muscle.
5.
The approach is made passing the Flexor carpi radialis with detachment of the Pronator quadratus muscle from the radius.
6.
At the upper border of the pronator quadratus muscle it pierces the interosseous membrane and reaches the back of the forearm, where it anastomoses with the dorsal interosseous artery.
7.
The anterior interosseous artery supplies the deep layer of the anterior compartment of the forearm, including the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus muscles.
8.
The pinching will simulate contraction of pronator quadratus, and will show the action of the muscle .-- talk 06 : 01, 7 May 2008 ( UTC)
9.
:Pronator quadratus runs from the lateral ( outside ) of the radius to the medial border of the ulna, and is found in the anterior compartment of the forearm.
10.
After the injury, the fracture is subject to deforming forces including those of the brachioradialis, pronator quadratus, and thumb extensors, as well as the weight of the hand.
