1

AC Shoulder Dislocation vs. Separation

AC Dislocations when AC tendon tears (acromion more prominent, clavicle may move more superior)
AC dislocations are more serious when coracoclavicular tendons (stabilizing) also tear = shoulder separation
Shoulder separates from clavicle and falls d/t weight

2

What is involved with subacromial bursitis?

Subacromial bursa (between supraspinatus tendon and acromion) becomes inflamed and tender d/t calcifications and inflammation of supraspinatus tendon
Painful on abduction (painful arc syndrome)

3

Glenohumeral ligaments

(3) Radiate from supraglenoid tubercle of scapular to anatomical neck of humerus

4

Coracohumeral ligament

From corocoid process to humerus

5

Transverse humeral ligament

from greater to lesser tubercle of the humerus - holds long head of biceps in place (in intertubercular groove)

6

Coracoacromial ligament

Corocoid process to acromion of scapula - provides resistance to upward force of humerus

7

Glenoid labrum

Lip of cartilage that slightly deepens glenoid fossa

8

Subacromial bursa

between supraspinatus tendon and acromion

9

Most common muscle torn in rotator cuff injuries

Supraspinatus

10

Most common nerve injured in shoulder dislocation and clinical manifestation?

Axillary nerve - deltoid unnerved - difficulty abducting to or above horizontal

11

Frozen Shoulder/Adhesive capsulitis of GH joint

Adhesive fibrosis/scarring between inflamed joint capsule of GH joint, rotator cuff, subacromial bursa and deltoid
Extend arm and rotate to abduct --> pressure on AC joint
