Describe the arthrokinematics at the SC joint during elevation.
The medial end of the clavicle rolls superiorly and glides inferiorly.
Describe the are arthrokinematics at the SC joint during retraction.
The medial end of the clavicle rolls and slides posteriorly.
What structure becomes taut during elevation of the clavicle?
Costoclavicular ligament (CCL)
What structure becomes slack during elevation of the clavicle?
Superior capsule and interclavicular ligament
What structures becomes taut during retraction of the clavicle?
CCL and Anterior capsular ligament
True or False: Upward and downward rotation at the AC joint occur in the sagittal plane.
False, it ocurrs in the frontal plane around a sagittal axis
What motion occurs at the SC and AC joint that creates Scapulothoracic elevation?
SC- elevation, AC- downward rotation
What motion occurs at the SC and AC joint that creates Scapulothoracic protraction?
SC-protraction, AC- Lateral horizontal plane adjustments
What motion occurs at the SC and AC joint that creates Scapulothoracic downward rotation?
SC-depression, AC-downward rotation
True or False: Rotation at the SC joint occurs in the sagittal plane.
True
What 2 ligaments comprise the Coracoclavicular ligament?
Conoid and trapezoid ligaments
True or False: the clavicle rotates posteriorly during scapular upward rotation?
True
True or False: the AC joint is classified as a plane joint.
True
True or False: the SC joint is classified as a plane joint.
False, it is classified as a saddle joint

What motions make up shoulder horizontal abduction?

• Horizontal abduction of the humerus


• Retraction of the scapula


• Retraction of the clavicle

What motions make up shoulder extension?

•Extension of the humerus


•Downward rotation and retraction of the scapula


•Depression and retraction of the clavicle

What is the closed packed position for the Glenohumeral joint?
There are two: Abduction concurrent with ER and Flexion concurrent with IR
True or False: the anterior band of the Coracohumeral becomes taut with shoulder flexion.
False, it becomes taut with shoulder extension.
During what motions does the inferior Glenohumeral ligament become taut?
All fibers: Abduction, Anterior band: ER, posterior band: IR

During what motion does the Conoid ligament become taut?

Retraction of the clavicle

What are the arthrokinematics at the Glenohumeral joint during shoulder IR in an open kinematic chain?
The humeral head rolls anteriorly and slides posteriorly
What is/are the arthrokinematics at the glenohumeral joint during shoulder flexion in an open kinematic chain?
Spin
What are the arthrokinematics at the Glenohumeral joint during shoulder ABD in an open kinematic chain?
The humeral head rolls superiorly (laterally) and slides posteriorly (medially)
What is the loosed packed position of the Glenohumeral joint?
55 degrees of ABD and 30 degrees of horizontal ADD

During what motions does the anterior middle and inferior GH ligaments become taut?

ER and Abduction

What motions does the clavicular portion of the Pect Major produce?

• Internal rotation of the shoulder

• Flexion of the shoulder


• Horizontal adduction of the shoulder
