CP2 UE MIDTERM EXAM QUESTIONS
AND ANSWERS 2025
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
,2 | Page
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. - 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
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
