Transcript of "Slides6"

  1. 1. Anatomy slidesElbow and Wrist
  2. 2. POK 1 “Guidance for Routine Handling “• These anatomy slides should help you focus your attention;• ? Think what structures are you targeting and locating & why• ? What are the bony landmarks• ? What will you applicators be• ? Where are your contact points• ? What structures might you stabilize/move
  3. 3. Elbow joint
  4. 4. Elbow joint movement
  5. 5. Elbow joint
  6. 6. Annular ligament
  7. 7. Myology (Muscles)• Muscles of the upper arm• Anterior – Biceps brachii – Brachialis• Posterior – Aconeus – Triceps Brachii• Lateral – Brachioradialis
  8. 8. Biceps brachii & Brachialis
  9. 9. Triceps brachii & Anconeus
  10. 10. Biceps brachii & Brachialis
  11. 11. Elbow flexion / Extension• Flexion; • Extension;• Brachialis • Triceps Brachii• Biceps Brachii • Anconeus• Brachioradialis
  12. 12. Forearm Pronation / Supination• Pronation; • Supination;• Pronator Quadratus • Supinator• Pronator teres • Biceps Brachii (with elbow flexed)
  13. 13. Biceps brachii• Origin – Long head - supraglenoid tubercle – Short head - coracoid process• Insertion – Radial tuberosity & bicipital aponeurosis• Action – Shoulder & elbow flexion, supination• Innervation – Musculocutaneus nerve (C5-C6)
  14. 14. The Wrist and Hand• Keep thinking about;• The relationship of all the bones of the upper Limb• What are the anatomical links?• What muscles have an effect over more than 1 joint ?• What are the main nerves that supply the Upper limb and hand?
  15. 15. Fibrous joints (Syndesmosis)
  16. 16. Types of Synovial Joints
  17. 17. Carpal bones• 8 carpal bones - form the carpus – Scaphoid = boat shaped – Lunate = moon/crescent shaped – Triquetral = three cornered – Pisiform = pea shaped – Hamate = hook shaped – Capitate = head – Trapezoid = no parallel sides – Trapezium = parallel sides
  18. 18. Supination & Pronation
  19. 19. Movements of the radiocarpal and midcarpal joints
  20. 20. Carpal tunnel
  21. 21. Deep flexors FDP FPL PQ
  22. 22. Superficial flexors PT FDS FCR FCU PL
  23. 23. Deep extensors Supinator APL EPB EPL EI
  24. 24. Superficial extensors ECU EDM ED
  25. 25. Thenarmuscles
  26. 26. Thenar & Hypothenar muscles Adductor pollicisOpponens digiti minimi Flexor Pollicis Brevis Flexor digiti minimi Opponens pollicis Abductor digiti minimi Abductor pollicis brevis
  27. 27. Radial nerve• Major nerve of the Posterior cord• C5,C6,C7,C8,T1• Supplies – Triceps – Anconeus – Brachialis (lat) – Brachioradialis – Ex Carpi Rad Long• At the LHE bifurcates – Deep interosseous – Superficial Rad nerve
  28. 28. Ulna nerve• Terminal Branch of the medial cord• C7,C8,T1• Supplies – Some wrist flexors – Flex Digit Prof – Flex Carpi Ulnaris
  29. 29. Median nerve• Arises from – Lateral Cord C5,C6,C7 – Medial Cord C8, T1• Supplies – Wrist Flexors – Thenar musclesCarpal tunnel
