    • Anatomy slidesElbow and Wrist
    • 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
    • Elbow joint
    • Elbow joint movement
    • Elbow joint
    • Annular ligament
    • Myology (Muscles)• Muscles of the upper arm• Anterior – Biceps brachii – Brachialis• Posterior – Aconeus – Triceps Brachii• Lateral – Brachioradialis
    • Biceps brachii & Brachialis
    • Triceps brachii & Anconeus
    • Biceps brachii & Brachialis
    • Elbow flexion / Extension• Flexion; • Extension;• Brachialis • Triceps Brachii• Biceps Brachii • Anconeus• Brachioradialis
    • Forearm Pronation / Supination• Pronation; • Supination;• Pronator Quadratus • Supinator• Pronator teres • Biceps Brachii (with elbow flexed)
    • 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)
    • 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?
    • Fibrous joints (Syndesmosis)
    • Types of Synovial Joints
    • 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
    • Supination & Pronation
    • Movements of the radiocarpal and midcarpal joints
    • Carpal tunnel
    • Deep flexors FDP FPL PQ
    • Superficial flexors PT FDS FCR FCU PL
    • Deep extensors Supinator APL EPB EPL EI
    • Superficial extensors ECU EDM ED
    • Thenarmuscles
    • Thenar & Hypothenar muscles Adductor pollicisOpponens digiti minimi Flexor Pollicis Brevis Flexor digiti minimi Opponens pollicis Abductor digiti minimi Abductor pollicis brevis
    • 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
    • Ulna nerve• Terminal Branch of the medial cord• C7,C8,T1• Supplies – Some wrist flexors – Flex Digit Prof – Flex Carpi Ulnaris
    • Median nerve• Arises from – Lateral Cord C5,C6,C7 – Medial Cord C8, T1• Supplies – Wrist Flexors – Thenar musclesCarpal tunnel
