1. Chapter 11 Elbow Joint
3 bones, 3 ligaments, 2 joints, 1 capsule

2. Joint Structure and Motions
Elbow flexion and extension
Forearm pronation and supination
Carrying angle
Flexion & Extension – uniaxial degrees
Forearm pronation – 0-80; supination 0-90; radioulnar joint
Carrying angle – 5 degrees males; degrees female

10. Common Elbow Pathologies
Lateral epicondylitis
Medial epicondylitis
Elbow dislocation
Supracondylar fracture
Lateral epicondylitis – tennis elbow; esp. ECRB
Medial Epicondylitis – golfer’s elbow
Supracondylar fracture – children with FOOSH;
Little league Elbow – stress of medial epicondyle
Pulled elbow/ nursemaid’s elbow – radial head subluxation; children under age of 5
Volkmann’s Ischemic contracture – damage to brachial artery
