25
Scapula begins to move at
30 degrees abduction
26
GH to scapula motion
2:1 ratio
27
Force couple muscles for protraction, upward rotations and elevation
UT, SA, lower trap
28
When does ER rotation of humerus begin and why?
75 degrees abd in order to prevent greater tubercle hitting superior ridge of glenoid fossa
29
What degrees and what ligament tighten causing clavicle to rotate post
110 abd and Coracoacromial lig tighten
30
T spine does what for full arm elevation single and double
Single: SB B/L: extend
31
Resting position for GH jt
55 abduction, 30 horiz add
32
AC/SC resting position
Resting by side in normal physiological position
33

AC and SC closed packed
AC 90 abduction SC full elevation
35
GH capsular patterns
ER, ABD, IR
36
AC/SC capsular pattern

37
Proper positioning humeral head
Don’t want more than 1/3 of the humeral head in front of acromion
38
Vertebral border of scap should be how many inches from SPs

39
The spine and inferior angle are at what thoracic levels
Spine T3 and inf angle T7
40
Normal anterior tilt of scap
10 degrees
41
Scapula rotates how many degrees anterior in frontal plane
30 degrees
42
AC and SC and clavicle angle
AC higher than SC 15-20
43
3 Elbow joints
Humeroulnar Humeroradial Prox radioulnar
44
Forearm, ulna, radius, interosseus membrane 3 joints
DRUJ PRUJ Radio ulnar syndesmosis
45
Carrying angle
In full extension the ulna deviates laterally producing 7-12 degree angulation between humerus and forearm
46
Humero radial joint arthrokinematics flx and ext
Flx: radial head glides anteriorly on capitulum Ext: same but glides post
47
Distal radio ulnar joint - articular disc purpose
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
Radio ulnar syndesmosis does what during supination
Tightens
49
Radius and ulna connected by
Oblique cord of syndesmosis
50
Proximal radioulnar joint lateral and medial surface
Lateral: radial head Medial: radial notch of ulna
51
Annular ligament
Stabilizes head of radius and connects it to the ulna
52
Quadrate ligament
Further connects radius and ulna, acts as brake for rotation
53
Main motion at Prox radioulnar joint
Rotation
54
Ulna and radius during pronation
Ulna and radius cross, motion limited by bone on bone contact of radius and ulna
55
Ulna and radius during supination
They become parallel, rotation limited by tightening of interosseus membrane, quadrate lig, and anterior lig of DRUJ
56
Pronation and supination radius
Radius does not rotate around stationary axis but rotates in annular ring Ulnar moves post/lat with pronation Ulna moves med/and with supination
