The shoulder girdle is comprised of which four joints? - (answer)Sternoclavicular (S/C)
Acromioclavicular (A/C)
Glenohumeral (G/H)
Scapulothoracic Articulation (S/T)
Sternoclavicular joint is what kind of joint - (answer)Complex saddle joint
Increases the congruity of the highly irregular joint surfaces - (answer)Sternoclavicular joint articular
disc
Ligaments of the sternoclavicular joint - (answer)SC ligament, interclavicular, Costoclavicular
Achieved by placing the arm down at the side of the body - (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 upwardly rotate to achieve this. - (answer)Closed packed
position of the SC joint
Conditions of the SC joint - (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° -
(answer)Osteoarthritis
Can be very serious injury may require open reduction surgery - (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 - (answer)Anterior dislocation with superior medial displacement of
SC joint

joint
Ligaments of the AC joint - (answer)Coracoclavicular ligament comprised of coronoid and trapezoid
ligaments, and AC ligament

This position is debatable - (answer)Loose packed position of the AC joint
Conditions of the AC joint - (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 -
