Capitulum
□ Where the fovea and the head of the radius articulate
Radial fossa
□ Head of the radius lies in full flexion
Trochlea
□ T notch articulates on the ulna
Coronoid fossa
□ Coronoid process lies in full flexion
Lateral and medial supracondylar ridges
□ Attachment site
 Extensor carpi radialis longus
 brachioradialis
Lateral and medial epicondyles
□ Major attachment site
 Lateral
◊ Extensor carpi radialis brevis
◊ Extensor digitorum
◊ Extensor carpi ulnaris
◊ Extensor digiti minimi
◊ Supinator
 Medial
◊ Pronator teres
◊ Flexor carpi radialis
◊ Palmaris longus
◊ Flexor carpi ulnaris
◊ Flexor digitorum superficialis
Olecronon fossa
□ Space for the olecronon process of the ulna

○ Ligaments



Ulnar collateral
□ Prevent or resist medial deviation
 Anterior band
 Posterior band
 Oblique band
 Radial collateral
□ Prevents or resists lateral deviation
 Annular
□ Holds the head of the radius against the ulna
 *** Nursemaids elbow ***

 "Clinically" testing the integrity of the ligaments
□ Medial collateral ligament
 The distal end if free to move/ proximal end is fixed
 Where would you "apply" the force to test integrity of ligament?
