quiz 1 shoulder

Question 1

inferior medial border is prominent at rest & inferior angle tilts dorsally w movement

acromion tilts anteriorly over thorax

what type of scap dyskinesis

Answer 1

Type I Scapular Dyskinesis

Question 2

med. border of scap being prominent and lifting away from posterior chest wall

can indicate SLAP lesion

Answer 2

Type II Scap Dyskinesis

Question 3

superior medial border of scap is elevated

shoulder shrug initiates movement and there is minimal winging

Answer 3

Type III Scap dyskinesis

Question 4

both scapulae are symmetrical at rest and during motion

Answer 4

Type IV Scap dyskinesis

Question 5

limits inferior translation and restricts anterior and lateral rotation up to 45 abduction

Answer 5

Superior Glenohumeral Ligament

Question 6

limits lateral rotation between 45-90 abduction

Answer 6

Middle Glenohumeral Ligament

Question 7

has an anterior and posterior band with an “axillary pouch” in between acting like a hammock

Answer 7

Inferior Glenohumeral Ligament

supports the humeral head above 90 abduction, limiting inferior translation while the anterior band tightens on lateral rotation and posterior band on medial rotation

*most important

Question 8

primarily limits inferior translation and helps limit lateral rotation below 60 degrees abduction

Answer 8

Coracohumeral Ligament

• found in rotator interval between the anterior border of the supraspinatus tendon and superior border of subscapularis tendon, uniting the two tendons anteriorly

Question 9

forms an arch over the humeral head, acting as a block to superior translation

Answer 9

Coracoacromial Ligament

Question 10

forms a roof over bicipital groove to hold the long head of biceps tendon in place

Answer 10

Transverse humeral Ligament
