  Radius (bone) - Wikipedia, the free encyclopedia
Beneath the neck, on the medial side, is an eminence, the radial tuberosity; its surface is divided into a posterior, rough portion, for the insertion of the tendon of the biceps brachii muscle, and an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone.
The lower fourth is prominent, and gives insertion to the pronator quadratus muscle, and attachment to the dorsal carpal ligament; it ends in a small tubercle, into which the tendon of the brachioradialis muscle is inserted.
The third is broad, for the passage of the tendons of the Extensor indicis proprius and Extensor digitorum communis.

It arises from the medial epicondyle by the common tendon; from the fascia of the forearm; and from the intermuscular septa between it and the Pronator teres laterally, the Palmaris longus medially, and the Flexor digitorum sublimis beneath.
It arises from the medial epicondyle of the humerus by the common tendon, from the intermuscular septa between it and the adjacent muscles, and from the antibrachial fascia.
It arises from the pronator ridge on the lower part of the volar surface of the body of the ulna; from the medial part of the volar surface of the lower fourth of the ulna; and from a strong aponeurosis which covers the medial third of the muscle.

Superficial muscles of the chest and front of the arm.
Sternocostal head: anterior surface of the sternum, the superior six costal cartilages, and the aponeurosis of the external oblique muscle.
The Pectoralis major is a thick, fan-shaped muscle, situated at the upper front (anterior) of the chest wall.

 Pronator quadratus - Wikipedia, the free encyclopedia
Pronator quadratus is a square shaped muscle on the distal forearm that acts to pronate (turn so the palm faces downwards) the hand.
Its fibres run perpendicular to the direction of the arm, running from the most distal quarter of the anterior ulna to the distal quarter of the anterior radius.
When pronator quadratus contracts, it pulls the lateral side of the radius towards the ulna, thus pronating the hand.

Radio-humeral joint - joint between concave part of end of radius and the capitulum of the humerus, 1° freedom, movement is a spinning as the forearm supinates and pronates.
Damage to either of these structures may lead to significant loss of function in the case of nerve damage or ischaemic damage to structures distal to the elbow if the brachial artery is severed.
Other structures that might be damages are the anteriorly placed muscle groups (biceps brachii, brachialis and possibly the forearm flexors and extensors) and the anteriorly placed joint structures such as the joint capsule etc.

Lateral wrist x-ray, a reveals abnormal bulging of a fat plane adjacent to an area of underlying osseous injury.
The ventral bulging of the fat plane overlying the pronator quadratus muscle has been coined the "pronator sign." Although it typically means underlying fracture is present, it may also be seen in simple soft-tissue injury of the same region.
It is a good sign and should alert the radiologist of possible fracture when present.
