Distal; medial origin

13

Proximal; lateral origin

14

Triceps brachii; Anconeus

16

Pronators

Pronator teres; Pronator quadratus

17

Supinators

Biceps brachii; Supinator

18

Specific history questions for elbow

Heavy lifting; fall on olecranon

19

Gunstock deformity

Varus angulation of elbow

20

MCL test

Apply valgus stress; (+) = Pain and laxity of MCL

21

LCL test

Apply varus stress; (+) = Pain and laxity of LCL

22

Annular ligment test

Passively pronate & supinate arm > pain; place hand around radial head to stabilize; passively pronate & supinate; (+) = pain disappears with pressure

23

Tennis Elbow Test

Elbow at 90; ask patient to extend wrist & hold; apply resistance; (+) = Pain at lateral epicondyle

24

Lateral epicondylitis

Tennis elbow; tendonitis of wrist extensors;

25

Lateral epicondylitis - S/Sx

S/Sx = pain at lateral epicondyle; DECREASED GRIP STRENGTH; LIFTING GALLON OF MILK PAINFUL

26

Lateral epicondylitis - Mechanism

Overuse of wrist extension

27

Cozen's test

Elbow at 90; passively flex wrist & radially deviate and hold in position; ask pt to actively extend elbow while provider holds wrist in place; (+) = pain at lateral epicondyle

28

Tests for Tennis Elbow/Lateral Epicondylitis

Tennis elbow test; Cozen's Test

29

Common Elbow Fractures

Distal humerus; Proximal ulna; Proximal radius

30

Potential complications of elbow fractures

Damage to brachial a. and/or Median n.

31

Common elbow contusions

Olecranon process (most common); Lateral condyle; Radial head (defensive wound); Biceps & triceps; ulnar n.

32

Elbow dislocation vs. subluxation

Will dislocate but will not sublux

33

Posterior Elbow dislocation - mechanism

Blow to anterior forearm of flexed elbow (posterior dislocation)

34

Anterior Elbow dislocation - mechanism

Blow to posterior upper arm of flexed elbow

35

MCL sprain

Most common elbow lig sprain

36

MCL sprain - mechanism

Mechanism = Hyperextension (FALLING BACKWARD ON OUTSTRETCHED ARM); VALGUS STRESS (BASEBALL PITCHER); hit from outside

37

MCL sprain - S/Sx

S/Sx = Pain, edema, point tenderness; (+) = Valgus stress test

38

LCL Sprain - Mechanism

Mechanism = Hyperextension; Hit from inside

39

LCL Sprain - S/Sx

S/Sx = More edema than MCL; point tender; (+) Varus stress test

40

Annular ligment sprain - Mechanism

Mechanism = Falling on outstretched arm sending force up arm & causing joint to split apart

41

Annular ligament sprain - S/Sx

S/Sx = pain around radial head; edema; MORE COMMON IN KIDS & ELDERLY

42

Radial Head dislocation - Mechanism

Mechanism = Falling on outstretched arm sending force up arm & causing joint to split apart

43

Olecranon bursitis - Mechanism

Mechanism = Fall on flexed elbow (most common); direct blow; Studying on elbow; high recurrence rate

44

Olecranon bursitis - S/Sx

S/Sx = Golfball or baseball size edema; pain possible; calcifications may develop

45

Medial Epicondylitis

Golfer's elbow; tendonitis of wrist flexors; less common than tennis elbow

46

Ulnar Compression Syndrome

Inflammed ulnar nerve

47

Ulnar Compression Syndrome - S/Sx

Pain, numbness, tingling along medial (ulnar) aspect of lower forearm & hand; (+) Tinel sign at ulnar n.

48

Anterior Interosseous Nerve Syndrome

Branch of median n. passing between heads of pronator teres

49

Anterior Interosseous Nerve Syndrome - S/Sx

Paralysis of flexors of index finger & thumb; (+) = Pinch test
