Olecranon process Attachment for triceps brachii tendon Patient with arm at side, elbow flexed approximately 30 degrees Bony prominence of the proximal ulna, just distal to the olecranon fossa and lateral to the medial epicondyle of the humerus
Tuberosity of the radius Insertion of the biceps brachii tendon Elbow flexed at 90 degrees Follow the biceps brachii muscle and tendon distally to the radius; once you lose the tendon the tuberosity lies just underneath your finger or thumb    
Radial shaft in supination Attachment of interosseous membrane, pronator quadratus, and wrist flexors Sitting with arm in supination Lateral forearm
Medial supracondylar ridge Serves as an attachment for the flexor muscles of the wrist Patient standing with the elbow flexes 30 degrees Located superior to the medial epicondyle of the humerus    
Radial shaft in pronation Also called the forearm Patient needs to be standing or seated with the elbow flexed at 90 degrees and then rotate the shaft laterally It attaches to the elbow (olecranon fossa) and it articulates with the capitellum and humerus on its distal end
Ulnar shaft in supination Origin of flexor digitorum profundus and pronator quadratus Arm resting on table, anatomic position Medial forearm in anatomic position
Ulnar shaft in pronation Serves as an attachment for the interosseous membrane Patient lying in the prone position with the arm relaxed When in pronation, the ulna will be located on the lateral side of the forearm. Crosses over the radius in pronation  
Lateral supracondylar ridge The site of the wrist extensors or the "mobile wad of 3" the brachioradialis, extensor carpi radialis longus, and the extensor carpi radialis brevis; also the brachioradialis originates from here Stand at the patient's side and hold the anterior lateral aspect of the arm, move upward in a linear fashion from the lateral epicondyle, and palpate a short bony ridge, palpate up and down the ridge to get a good feel for its prominence Located on the posterior distal end of the humerus above the lateral epicondyle
Styloid process-radius Reference point of carpal palpation; insertion of brachioradialis Forearm relaxed on table Distal tip of radius
Styloid process-ulna The extensor carpi ulnaris tendon runs thru a groove in the distal tip of the ulna styloid process Patient standing, relaxed The ulna styloid process is located both medially and posteriorly on the wrist in the anatomic position

Tubercle of the radius (Listerís Tubercle) When the hand is broken down into zones the tubercle of the radius makes up the 2nd zone Have the patient's hand and wrist in a neutral position It is the bony ridge located between the ulna and radius on the posterior and distal aspect of these two bones, between the ulna and radius distally
