  1. Ch. 20 Elbow and Forearm

  2. Objectives • Define the major landmarks of the elbow • List major injuries and conditions of the elbow

  3. Anatomy • Hinge joint • 3 major bones • Humerus • Radius-on thumb side of forearm • Ulna-on pinky side of forearm • Ulna is hooked on the end of the humerus • Radius rests next to humerus therefore allowing supination and pronation

  4. Ligaments • Ulnar Collateral-on the medial side • Radial Collateral-on the lateral side • Annular-encircles the head of the radius • Interosseous Membrane-connects the radius to the ulna

  5. Muscles • Flexors • Brachialis-major flexor • Biceps Brachii-also supinates hand • Brachioradialis • Extensors • Triceps Brachii • Anconeus

  6. Muscles

  7. Contusion • Vulnerable area due to lack of padding • Result of direct blow or fall • S/S: swelling and/or bruising • Treatment: RICE, x-ray if not improving

  8. Olecranon Bursitis • Caused by direct blow or fall • S/S: swelling, pain • Treatment: RICE, can be aspirated by doctor • Easily infected due to abrasions on elbow

  9. Ulnar Nerve Contusion • Hitting your funny bone • The ulnar nerve runs behind the medial epicondyle • Caused by a direct blow • S/S: pain, burning and tingling sensation down medial side of forearm • Should alleviate in mins

  10. Elbow Sprains • MOI: hyperextension or valgus/varus stress • S/S: ‘pop’, sharp pain, swelling • Ulnar collateral sprains are more common due to throwing mechanics • Treatment: RICE, strengthen wrist flexor or extensors, surgery if ruptured

  11. Medial Epicondylitis • Golfer’s Elbow • Little League Elbow • Irritation of the wrist flexors causing pain at the medial epicondyle • Treat with RICE, NSAIDs, change in mechanics

  12. Lateral Epicondylitis • Tennis Elbow • Inflammation of the wrist extensors causing pain at the lateral epicondyle • Same treatment as medial epicondylitis

  13. Elbow Dislocation • Most common is posterior dislocation • MOI: falling on outstretched hand • Obvious deformity • Splint, stabilize, check circulation, check motor and sensory function • Refer to doctor

  14. Elbow Fracture • Direct blow or falling on arm • Common in children • S/S: Point tenderness, swelling, increase pain with movement • Refer to doctor for x-rays

  15. Volkmann’s Contracture • Occurs in the absence of blood flow to the forearm • Causes muscles to shorten • Usually associated with elbow fractures, bleeding disorders, animal bites
