1) The shoulder girdle is comprised of which four Sternoclavicular (S/C)
joints? Acromioclavicular (A/C)
Glenohumeral (G/H)
Scapulothoracic Articulation
(S/T)
2) Sternoclavicular joint is what kind of joint Complex saddle joint
3) Increases the congruity of the highly irregular Sternoclavicular joint articular
joint surfaces disc
4) Ligaments of the sternoclavicular joint SC ligament, interclavicular,
Costoclavicular
5) Achieved by placing the arm down at the side Loose packed position of the SC
of the body joint
6) Achieved through maximum shoulder Closed packed position of the
elevation, when the GH joint exceeds greater SC joint
than 110° of flexion or abduction. The clavicle
, must upwardly rotate to achieve this.
7) Conditions of the SC joint Osteoarthritis, sprain,
dislocation, all are not that
common, clavicular fracture is
most likely
8) With ankylosis of a SC joint shoulder elevation Osteoarthritis
is severely limited to approximately 19°
9) Can be very serious injury may require open Posterior dislocation of SC joint
reduction surgery
10) Most common dislocation, usually occurs due Anterior dislocation with
to direct trauma to the side of the shoulder, superior medial displacement of
such as an impact or a fall, typically benign SC joint
11) Acromioclavicular joint is what kind of joint? Planer joint with incongruent
surfaces
12) High degree of variability between individuals Articular disc of the AC joint
and within individuals
13) Ligaments of the AC joint Coracoclavicular ligament
comprised of coronoid and
trapezoid ligaments, and AC
ligament
14) Achieved by bringing the GH joint into 90° of AC joint closed packed position
abduction
15) This position is debatable Loose packed position of the
, AC joint
16) Conditions of the AC joint Osteoarthritis, osteolysis, AC
joint dislocation or shoulder
separation
17) Resorption of the subchondral bone of the Osteolysis
distal clavicle, can be due to trauma or
repetitive stress
18) Common mechanism of injury is direct impact AC joint dislocation or shoulder
to the lateral aspect of shoulder or a fall on separation
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
19) One of the most mobile joints Glenohumeral
20) The glenohumeral joint is what type of joint Ball and socket joint
21) The head of the humerus articulates with what. Glenoid fossa
To form the GH joint
22) The GH joint at the glenoid fossa is supported Glenoid labum, ligaments, joint
by what capsule, rotator cuff
23) What ligaments are in the GH joint? The superior, middle, inferior,
and posterior GH ligaments
24) What are the rotator cuff muscles? (SITS) Supraspinatus, infraspinatus,
teres minor, subscapularis
