Flashcards in Orthopedics Deck (15):

What is the most common type of shoulder dislocation and what is the mode of injury for this typically?

anterior dislocation




fall on an outstretched arm (contact sports in younger patients and falls in older patients)

A image thumb

Only 2 - 4% of shoulder dislocations are posterior. What type of occurrence is this most commonly seen with?


A image thumb

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

abducted and externally rotated

"squaring" of the shoulder: loss of rounded appearance (humeral head) and sharp prominence of the acromion 

A image thumb

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)

A image thumb

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 


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


Treatment for shoulder dislocations


post-reduction films

sling and swath

physical therapy


what part of the clavicle is most often fractured?

middle third


A image thumb

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 

A image thumb

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

elevation of the clavicle

AC joint separation


A image thumb

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

A image thumb

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

cross-chest testing


A image thumb

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
