|---|---|
| Pronator Quadratus O, I, A |  O: medial anterior surface of distal ulna, I: lateral anterior surface of distal radius, A: Pronate the forearm |
| Pronator Teres O, I, A | O:medial epicondyle of the humerus, common flexor tendon and coronoid process of the ulna, I:middle of the lateral surface of radius. A: pronate forearm, assist to flex the elbow |
| Supinator O, I, A | O:radial collateral ligament, annular ligament and supinator crest of the ulna (lateral epicondyle). I; lateral proximal radial shaft. A: supinates forearm. |
| Palmaris longus O, I, A | O:common flexor tendon from medial epicondyle, I:flexor retinaculum and palmar aponeurosis, A:tense the palmar fascia, flex wrist, flex elbow. |
| extensor digitorum communis | O Lateral epicondyle of humerus, I: second to fifth digits, A:extends the hand, wrist and fingers. |
| Elbow/forearm protocol | 1)pronator teres, 2)supinator, 3)extensor digitorum communis, 4)3 flexors (flexor carpi ulnaris, flexor carpi radialis, palmaris longus) |
| pronator teres location | Distal tip of equilateral triangle drawn from Ht 3 and Pc 3, needle perpendicular .5-1 inch |
| Supinator location | With forearm pronated, it is deep to LI 9 (or, 1.5 cun distal to Lu 5 and .5 towards radial side) |
| Extensor digitorum communis location | Tip of equilateral triangle drawn fro LI 8 and LI 9, on the ulnar side. |
| 3 Flexors (carpi ulnaris, radialis, longus) | On a line drawn from the medial epicondyle of the humerus to Ht 7, Pc 7, and Lu 9, on the proximal 1/3rd between these points. Ulnaris is to Ht 7, radialis is to Pc 7 and P. longus is to Lu 9) |
| Other points | 1) pronator quadratus (Pc 6 - use for true carpal tunnel in addition to regular protocol), 2) thread both sides of insertion of wrist flexors (medial) or extensors (lateral)-->to tx epicondylitis. |
| Pronator teres syndrome | Muscle tension can cut off median nerve and mimic carpal tunnel |
| How to access radial nerve | via li 9 |
| how to access median nerve | via PC 3 |
| how to access ulnar nerve | Si |
| What prevents varus in elbow | lateral collateral ligament |
| what prevents valgus in elbow | medial collateral ligament |
| annular ligament | ring in which radius rotates |
