3

What is the presentation for a patient with anterior shoulder dislocation?

4

What is a Bankart Lesion and what kind of injury is it associated with?

fracture of the anterior inferior glenoid following impaction of the humeral head against the glenoid  (anterior shoulder dislocation)

5

What are some conditions associated with a shoulder dislocation?

1. Bankart Lesion: fracture of glenoid cavity

2. Hill-Sachs Lesion: dent in the humeral head 

3. axillary nerve injury

4. rotator cuff tear: (MC in older patients)

5. labral tear: labrum is the cartilage that surrounds the glenoid 

6

What is a Hill-Sachs lesion?

dent in the humeral head

compression chondral injury of the posterior superior humeral head following impaction against the glenoid

Sometimes with a shoulder injury, a patient can have axillary nerve damage. What are symptoms of this?

transient neurapraxia present in 5% of shoulder dislocations

 

can present with numbness or tingling over the lateral shoulder

8

Treatment for shoulder dislocations

reduce

post-reduction films

sling and swath

physical therapy

9

middle third

10

What is the treatment for a clavicle fracture?

simply arm sling or figure 8 sling: 4 - 6 weeks in adult, ortho consult if proximal 1/3

begin PT after 4 wks with light strengthening after 6 wks

11

What is a step off deformity and what injury would you see it with?

elevation of the clavicle

AC joint separation

12

How do you appropriately grade acromioclavicular separations?

XRAY is taken with the person holding a weight to assess the level of injury to the joint

13

A patient with shoulder separation (AC joint separation) will have pain with what kind of test?

cross-chest testing

14

Management of AC joint separation

Conservative management is possible for mild to moderate injuries because they can be managed with sling and analgesia

 

more severe injuries will require operative repair
