Q

Force couple muscles for protraction, upward rotations and elevation

A

UT, SA, lower trap

28
Q

When does ER rotation of humerus begin and why?

A

75 degrees abd in order to prevent greater tubercle hitting superior ridge of glenoid fossa

29
Q

What degrees and what ligament tighten causing clavicle to rotate post

A

110 abd and Coracoacromial lig tighten

30
Q

T spine does what for full arm elevation single and double

A

Single: SB
B/L: extend

31
Q

Resting position for GH jt

A

55 abduction, 30 horiz add

32
Q

AC/SC resting position

A

Resting by side in normal physiological position

33
Q

GH closed packed

A

Full abduction and ER

34
Q

AC and SC closed packed

A

AC 90 abduction

SC full elevation

35
Q

GH capsular patterns

A

ER, ABD, IR

36
Q

AC/SC capsular pattern

A

ERP

37
Q

Proper positioning humeral head

A

Don’t want more than 1/3 of the humeral head in front of acromion

38
Q

Vertebral border of scap should be how many inches from SPs

A

3

39
Q

The spine and inferior angle are at what thoracic levels

A

Spine T3 and inf angle T7

40
Q

Normal anterior tilt of scap

A

10 degrees

41
Q

Scapula rotates how many degrees anterior in frontal plane

A

30 degrees

42
Q

AC and SC and clavicle angle

A

AC higher than SC

15-20

43
Q

3 Elbow joints

A

Humeroulnar
Humeroradial
Prox radioulnar

44
Q

Forearm, ulna, radius, interosseus membrane 3 joints

A

DRUJ
PRUJ
Radio ulnar syndesmosis

45
Q

Carrying angle

A

In full extension the ulna deviates laterally producing 7-12 degree angulation between humerus and forearm

46
Q

Humero radial joint arthrokinematics flx and ext

A

Flx: radial head glides anteriorly on capitulum
Ext: same but glides post

47
Q

Distal radio ulnar joint
- articular disc purpose

A

Connects radius and ulna
Separates radio ulnar joint from radio carpal joint
Provides dual articular surface
- proximal surface disc sweeps
- distal surface triquetrum glides

48
Q

Radio ulnar syndesmosis does what during supination

A

Tightens

49
Q

Radius and ulna connected by

A

Oblique cord of syndesmosis

50
Q

Proximal radioulnar joint lateral and medial surface

A

Lateral: radial head
Medial: radial notch of ulna

51
Q

Annular ligament

A

Stabilizes head of radius and connects it to the ulna

52
Q

Quadrate ligament

A

Further connects radius and ulna, acts as brake for rotation

53
Q

Main motion at Prox radioulnar joint

A

Rotation

54
Q

Ulna and radius during pronation

A

Ulna and radius cross, motion limited by bone on bone contact of radius and ulna

55
Q

Ulna and radius during supination

A

They become parallel, rotation limited by tightening of interosseus membrane, quadrate lig, and anterior lig of DRUJ

56
Q

Pronation and supination radius

A

Radius does not rotate around stationary axis but rotates in annular ring

Ulnar moves post/lat with pronation
Ulna moves med/and with supination

57
Q

Elbow resting position

A

70 flx, slight sup

58
Q

Radiohumeral resting position

A

Full ext/sup

59
Q

PRUJ resting position

A

70 flx, 35 sup

60
Q

DRUJ resting position

A

10 sup

63
Q

PRUJ closed

A

5 sup

64
Q

DRUJ closed packed

A

5 sup

65
Q

Elbow capsular pattern and forearm

A

Elbow: flx over ext
Forearm: pro/sup equal

66
Q
