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 diD. 1/2 fdprofundus, FCU all else medianE. Spinoglenoid and supraspinal notch on the floor of the spine of the scapulaF. 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 G. Flex dig profundus- does the tips
Then flex thumb flex pol longus
Then pronate with pronator quadratusH. 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 FDPI. <10mm- >13 is abnormalJ. Biceps brachii supinator and flexor, brachialis attaches to ulna so only flexion and coracobrachialis all musculocutaneous n.K. Obrien’s test- pain worse with resisted extension of pronated hand relieved with supinationL. Medial half Lumbricles, opponens POLLICIS abducter POLLICIS & flexor POLLICIS all median others are all ulnar (PADS and DABS etc)M. 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. N. Aplepb 1st dorsal compartmentO. Ulnar: 1 and 1/2- Flexor carpi ulnaris and Flex dig profundus (ulnar half). Nerve is pinched between these 2 muscles.P.

Ext indices proprius (index finger)R. 12- 6 deep, 6 superficialS. 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. From lateral epicondyle- 6 superficial: brachioradialis supinates. But if pronated causes elbow flexion2&3 ECRL&B, 4 extensor digitorum, 5 ext digiti minimi, 6 Ext carpi ulnaris from medial to radial to ulnar |
