Sternoclavicular joint is what kind of joint Ans: Complex saddle
joint
Increases the congruity of the highly irregular joint surfaces Ans:
Sternoclavicular joint articular disc
Ligaments of the sternoclavicular joint Ans: SC ligament,
interclavicular, Costoclavicular
Achieved by placing the arm down at the side of the body Ans:
Loose packed position of the SC joint
, 2
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. Ans: Closed
packed position of the SC joint
Conditions of the SC joint Ans: Osteoarthritis, sprain, dislocation, all
are not that common, clavicular fracture is most likely
© 2025 Assignment Expert
With ankylosis of a SC joint shoulder elevation is severely limited to
approximately 19° Ans: Osteoarthritis
Can be very serious injury may require open reduction surgery

the side of the shoulder, such as an impact or a fall, typically
benign Ans: Anterior dislocation with superior medial
displacement of SC joint
Acromioclavicular joint is what kind of joint? Ans: Planer joint with
incongruent surfaces

Ligaments of the AC joint Ans: Coracoclavicular ligament
comprised of coronoid and trapezoid ligaments, and AC ligament
, 3
Achieved by bringing the GH joint into 90° of abduction Ans: AC
joint closed packed position
This position is debatable Ans: Loose packed position of the AC
joint
Conditions of the AC joint Ans: Osteoarthritis, osteolysis, AC joint
dislocation or shoulder separation
© 2025 Assignment Expert
Resorption of the subchondral bone of the distal clavicle, can be
due to trauma or repetitive stress Ans: Osteolysis
Guru01 - Stuvia
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 Ans:
AC joint dislocation or shoulder separation
