1. Lesson Objectives Reviewing the anatomy of the Elbow Bones & Joints
Ligaments, tendons muscles
Movements of the elbow/forearm

2. Elbow Anatomy Bones – Humerus, Ulna & Radius Humero-ulnar Joint:
Hinge (sometimes called “Limited Ball & Socket”)
Motions – Flexion & Extension
Humero-Radial Joint:
Hinge

3. Anatomy cont’d Proximal (& Distal) Radio-ulnar Joint:
Pivot
Motions – pronation & supination
Olecranon Process - Point of the Elbow (part of the ulna) where triceps attaches
Radial Tuberosity – bump on the radius where biceps tendon attaches

4. Elbow Anatomy (cont’d)
Trochlea – distal & medial portion of the articular surface of the humerus
Capitulum - distal & lateral portion of the articular surface of the humerus
Epicondyles – Medial & Lateral prominences of the humerus
Major Ligaments:
Ulnar Collateral, Radial Collateral, Annular & Capsular

5. Ligaments Annular Radial Collateral (RCL) Ulnar Collateral (UCL)
ligament that wraps horizontally around the head of the radius & holds the proximal radio-ulnar joint together
Radial Collateral (RCL)
connects radius and humerus
lateral
Ulnar Collateral (UCL)
connects ulna and humerus
medial

11. Elbow & Forearm Joints Bicipital Groove Humeroradial joint
Olecranon fossa
Humeroulnar joint
Humeroradial joint
Proximal Radioulnar joint
Bicipital Groove

12. Elbow & Forearm Joints

13. FOREARM JOINTS

14. Muscles & Motions: Flexion – Biceps, Brachioradialis, Brachialis
Extension -Triceps & Anconeus
Pronation – Pronator Teres, Pronator Quadratus
Supination – Biceps, Supinator

16. Elbow Injuries Most occur from overuse
Racket (tennis) and Throwing (baseball/softball) sports have a high incidence of injuries

17. Lateral Epicondylitis – “Tennis Elbow”
Occurs from overuse
Injury to the tendon connecting extensor muscles to lateral epicondyle

18. Medial Epicondylitis – “Little League Elbow” / “Golfer’s Elbow”

19. Olecranon Bursitis “Student’s Elbow”
Cause: hard blow or repeated minor injuries
Inflammation of the bursa - bursitis

20. Avulsion Fx
Medial Epicondyle most common

21. Elbow Dislocation Cause: most common is a fall on an outstretched arm
Ulna (olecranon process) dislocates from the humerus

22. Ulnar Nerve Contusion AKA: hitting your funny bone
Cause: knocking your ulna against a hard surface
Ulnar Nerve runs along the medial surface of the elbow
Can become entrapped due to:
Direct trauma
Repetitive strain
Progressive compression (Cubital Tunnel Syndrome)

23. UCL Constructive Surgery
Ulnar Collateral Ligament (UCL)
AKA: Tommy John Surgery
Surgery to repair & replace the UCL
Over time tiny and large tears occur; eventually rupturing
Named after famous LA Dodgers Pitcher Tommy John
