The shoulder girdle is comprised of which four joints? - CORRECT
ANSWER Sternoclavicular (S/C)
Acromioclavicular (A/C)
Glenohumeral (G/H)
Scapulothoracic Articulation (S/T)
Sternoclavicular joint is what kind of joint - CORRECT ANSWER
Complex saddle joint
Increases the congruity of the highly irregular joint surfaces -
CORRECT ANSWER Sternoclavicular joint articular disc
Ligaments of the sternoclavicular joint - CORRECT ANSWER SC
ligament, interclavicular, Costoclavicular
Achieved by placing the arm down at the side of the body - CORRECT
ANSWER Loose packed position of the SC joint
Achieved through maximum shoulder elevation, when the GH joint
exceeds greater than 110° of flexion or abduction. The clavicle must
,MEDSTUDY.COM
upwardly rotate to achieve this. - CORRECT ANSWER Closed packed
position of the SC joint
Conditions of the SC joint - CORRECT ANSWER Osteoarthritis,
sprain, dislocation, all are not that common, clavicular fracture is most
likely
With ankylosis of a SC joint shoulder elevation is severely limited to
approximately 19° - CORRECT ANSWER Osteoarthritis
Can be very serious injury may require open reduction surgery -
CORRECT ANSWER Posterior dislocation of SC joint
Most common dislocation, usually occurs due to direct trauma to the
side of the shoulder, such as an impact or a fall, typically benign -
CORRECT ANSWER Anterior dislocation with superior medial
displacement of SC joint
Acromioclavicular joint is what kind of joint? - CORRECT ANSWER
Planer joint with incongruent surfaces
High degree of variability between individuals and within individuals -
CORRECT ANSWER Articular disc of the AC joint
Ligaments of the AC joint - CORRECT ANSWER Coracoclavicular
ligament comprised of coronoid and trapezoid ligaments, and AC
ligament
,MEDSTUDY.COM
Achieved by bringing the GH joint into 90° of abduction - CORRECT
ANSWER AC joint closed packed position
This position is debatable - CORRECT ANSWER Loose packed
position of the AC joint
Conditions of the AC joint - CORRECT ANSWER Osteoarthritis,
osteolysis, AC joint dislocation or shoulder separation
Resorption of the subchondral bone of the distal clavicle, can be due to
trauma or repetitive stress - CORRECT ANSWER Osteolysis
Common mechanism of injury is direct impact to the lateral aspect of
shoulder or a fall on outstretched hand, graded on damage to ligaments
and displacement of clavicle, six types of grades of separation, grades 4
to 6 are variations of grade 3 - CORRECT ANSWER AC joint
dislocation or shoulder separation
One of the most mobile joints - CORRECT ANSWER Glenohumeral
The glenohumeral joint is what type of joint - CORRECT ANSWER
Ball and socket joint
The head of the humerus articulates with what. To form the GH joint -
CORRECT ANSWER Glenoid fossa
, MEDSTUDY.COM
The GH joint at the glenoid fossa is supported by what - CORRECT
ANSWER Glenoid labum, ligaments, joint capsule, rotator cuff
What ligaments are in the GH joint? - CORRECT ANSWER The
superior, middle, inferior, and posterior GH ligaments
What are the rotator cuff muscles? (SITS) - CORRECT ANSWER
Supraspinatus, infraspinatus, teres minor, subscapularis muscles
In the coronal plane line of the scapula with approximately 38-40° of
abduction - CORRECT ANSWER Loose packed position of the GH
joint
Full abduction and full external rotation - CORRECT ANSWER
Closed packed position of the GH joint
Prevents inferior displacement of the humerus along with the
supraspinatus, taught with adduction and inferior and posterior
translation - CORRECT ANSWER Superior ligament at the GH joint
Prevents anterior translation of the head of the humerus and external
rotation, becomes taught at 90° abduction and stabilizes internal
rotation, acts as a sling for the humeral head - CORRECT ANSWER
Inferior ligament at the GH joint
