Q

Pain of the shoulder at 45 degrees or below indicates what degree of impingement? What about at 60-70 degrees?

Study These Flashcards
A
  • Severe (45 or below)

- Moderate (60-70)

20
Q

What is the treatment for shoulder impingement?

Study These Flashcards
A
  • Ice, NSAIDs, activity modification
  • NO arm sling
  • Physical Therapy referral
  • Follow up 2-3 weeks later to confirm improvement in symptoms
  • May have benefit from steroid injections if persistent
  • Surgery if symptoms are severe and anatomic variant could be improved
21
Q

What is the MOI for a labral tear?

Study These Flashcards
A
  • FOOSH or sudden pull

- Repetitive overuse (throwing athletes, laborer)

22
Q

What is the clinical presentation of a labral tear?

Study These Flashcards
A
  • Pain if acute
  • Clicking/catching if chronic
  • Frequently associated with other shoulder pathology
23
Q

What is typically observed on physical exam in a labral tear?

Study These Flashcards
A
  • Biceps tendon pain
  • Restricted internal/external rotation of the glenohumeral joint
  • Motion dysfunction of the scapula
  • Positive Anterior Glide, Speed’s, O’Brien’s test
24
Q

What imaging can be done for a labral tear?

Study These Flashcards
A
  • Radiographs (initial)
  • MRA > MRI
  • Arthoscopy for definitive diagnosis
25
What is the preferred treatment for a labral tear?
- Nonsurgical | - NSAIDs and PT
26
How is adhesive capulitis diagnosed?
- ROM tests confirm reduced ROM at glenohumeral joint in 2 or more planes (passive and active) (Positive Apley Scratch Test) - Severe pain - Loss of ROM is a mechanical restriction, not pain restriction - Abduction/External rotation most common
27
What is the treatment for adhesive capsulitis?
- Consult Physical Therapy - Most cases are self limited - Conservative treatment
28
What is the MOI for an acromioclavicular injury?
Fall onto the tip of the shoulder with arm tucked into the side
29
How does a patient typically present with an acromioclavicular injury?
Bump on the shoulder that is worse at bedtime
30
What is typical on the physical exam of a patient with an AC sprain?
- AC joint swelling and possible deformity - AC joint tenderness - Pain aggravated with downward traction - Pain with passive cross-body adduction (Cross-Over Test)
31
In a Grade I AC injury, is there any tear/separation? What is seen on imaging?
There is pain, but no separation. Radiographs will be normal
32
In a Grade II AC injury, is there any tear/separation? What is seen on imaging?
There is separation of the Acromioclavicular (AC) ligament (partial separation). Radiographs show slight widening and offset at the clavicle.
33
In a Grade III AC injury, is there any tear/separation? What is seen on imaging?
There is separation of the Acromioclavicular (AC) AND Coracoclavicular (CC) ligaments. Radiographs show distal clavicle at or above the superior margin of the acromion.
34
What is the treatment for an AC sprain?
- Shoulder immobilizer for 3-4 weeks - Restriction of overhead, reaching, and weights - Ice, rest, NSAIDs, and steroid injections if not improving after 2-4 weeks - Surgical consideration for Grade III
35
Where do most clavicular fractures occur?
In the middle 1/3 of the clavicle
36
Which clavicular fracture location should you evaluate for internal organ involvement and refer to a specialist?
Proximal 1/3 (least common)
37
What is the clinical presentation of a clavicular fracture?
- Visual deformity - Tenderness - Decreased ROM
38
What imaging is appropriate to obtain for a clavicular fracture?
Single AP radiograph of the clavicle
39
What is the treatment for a clavicular fracture?
Conservative treatment for non-displaced, minimally displaced, or pediatric patients - Sling vs figure of 8 harness - Analgesics, muscle relaxers - Sleep upright Ortho Referral: - Displaced mid clavicle fracture and all proximal and distal 1/3 fractures - Surgery
40
What can cause subacromial bursitis?
- Repetitive movement | - May result from systemic disease (RA, gout, sepsis)
41
What is the clinical presentation of subacromial bursitis?
- Pain with ROM and rest - Localized tenderness to palpation - May be associated with rotator cuff tendonitis - May cause impingement syndrome
42
What is the treatment for subacromial bursitis?
- Ice and NSAIDs - Restriction of overuse - Aspiration and Steroid injection (do not do injection if you suspect sepsis or aspirate)
43
What is the clinical presentation of biceps tendonitis?
- Pain to anterior shoulder with abduction and external rotation - Max point of tenderness along bicipital groove - Popping sensation - Weakness - Positive Yergason's, Speed's
44
What can be seen on clinical presentation of an individual with a ruptured biceps tendon?
"Popeye Deformity"
45
What is the treatment of biceps tendonitis?
- NSAIDs and rest to reduce inflammation - Physical therapy to help with strength and prevent rupture - Surgery for ruptured tendon
