| A. Ext indices proprius (index finger)B. Ulnar: 1 and 1/2- Flexor carpi ulnaris and Flex dig profundus (ulnar half). Nerve is pinched between these 2 muscles.C. Biceps brachii supinator and flexor, brachialis attaches to ulna so only flexion and coracobrachialis all musculocutaneous n.D. FDProfundus, curls up all fingers, then need thumb flexed (F pollicis logis), then need to pronate- pronator quadratus. All innervated by median except ulnar 1 and 1/2 muscles FCU and FDPE. 20 12 extensors (6 deep, 6superficial) , 8 flexors (4,1,3)F. 1. Brachioradialis- lateral epicondyle to radius-supinates but if wrist is pronated, it flexes elbow. 2. Ext carp rad longus and brev, 4. Ext digitorum all 4 fingers, 5. Ext Dig minimi, 6. Ext carpi ulnaris. G. 1/2 fdprofundus, FCU all else medianH. 1. Anconius (small triangular muscle causes extension of elbow), Supinator- opposite pronator teres, snuffbox brevis sandwich. 2 bottom are abductor pollicis long, ext pol brevis, ext pol longus. And finally ext indicisis to index finger. From prox to diI. 12- 6 deep, 6 superficialJ. Spinoglenoid and supraspinal notch on the floor of the spine of the scapulaK. SSn, axillary, branches of subscap and musculocutaneous (not usually) and supraclavicularL. 8 (4 superficial, 1 middle, 3 deep) put thumb on medial epicondyle and fingers across and say pass fail, pass fail. Pronator teres flips radius over, flexor carpi radialis, palmarus longus, flexar carpi ulnaris. Flexor dig superficialis M. 1/2 LOAF- lumbricles, opponens, abductor flexor pollisis N. <10mm- >13 is abnormalO. Common extensor tendon- ECRB EDC ECU- crozens test 3rd digit testP. No only scapula to radius- causes supinationQ. Obrien’s test- pain worse with resisted extension of pronated hand relieved with supinationR. Palmar cutaneous branch at radial side just prox to flexor retinaculum and cutaneous branch of ulnarS. Upper lateral brachial cutaneous nerve (branch of axillary nerve that innervates lateral shoulder and skin over the deltoid muscle). Medial brachial brachial cutaneous n and intercostobrachial cutaneous nerves (upper medial arm), biceps is Mabc nT. Flex dig profundus- does the tips
Then flex thumb flex pol longus
Then pronate with pronator quadratus |
