Shoulder: Acromioclavicular Joint Injury
general
Etiology: A.K.A “shoulder separation”
Microtears or large tears of ligaments connecting the acromion and clavicle
Disruption of the acromioclavicular (AC) and coracoclavicular (CC) ligaments
Most common in male athletes
Mechanism: Direct blow to shoulder or fall onto shoulder
Common symptoms/complaints:
Pain at superior shoulder over the AC joint
Decreased strength
Shoulder: Acromioclavicular Joint injury
PE and testing
Physical exam:
Tenderness with palpation of AC joint
Edema at AC joint
Diminished strength and ROM
Testing:
X-rays will show varying degrees of separation depending on type of injury
Bilateral shoulder radiographs are helpful
Acromioclavicular Joint injury
Shoulder: Acromioclavicular Joint injury
Tx and complictions
Treatment:
Depends on severity of displacement
Type I, II and III (< 2cm of clavicle displacement) –> Sling, rest, ice, NSAIDs
Goal: Early ROM – regain function @ 6 w, back to normal activity @ 12 weeks
Type IV, V, VI – surgical fixation: hook plate, screw, CC screw, dog bone
Goal: Immobilize for 6 weeks & back to normal activity 6 months
Complications:
AC joint arthritis
Chronic instability
Shoulder: Acromioclavicular Joint Arthritis (OA)
General
Etiology: repetitive microtrauma resulting in degenerative loss of cartilage at the joint due to wear and tear
More common with age & weightlifters (heavy overhead activities)
Common symptoms/complaints:
Pain with overhead motion
Pain with sleeping on side
Grinding sensation at AC joint
Shoulder: Acromioclavicular Joint Arthritis
PE and testing
Physical exam:
TTP at AC joint
Pain with cross arm test
Testing:
X-rays will show joint space narrowing, osteophytes and maybe subchondral cysts
Shoulder:Acromioclavicular Joint Arthritis
Tx and complications
Treatment:
NSAIDs
Physical therapy – avoid overhead movements/strengthen shoulder girdle
Steroid injection – temporary relief
Surgical resection of the end of the clavicle (must take care not to take too much and destabilize the joint)
Complications:
AC joint instability
Persistent pain (incomplete resection)
Heterotopic ossification (HO)
Shoulder: Subacromial Impingement
general
Most common complaints
Referred pain?
Etiology:
Diminished space between the end of the acromion and the humerus
Compression of rotator cuff muscles by superior structures causing “pinching” of the structures beneath resulting in inflammation (bursitis)
A.K.A – Subacromial Bursitis
Common symptoms/complaints:
Pain with overhead activity
Referred pain into the deltoid and mid- arm
Shoulder: Subacromial Impingement
PE and testing
Physical exam:
Pain with overhead AROM and PROM (forward flexion and abduction)
+ Neer & Hawkins Tests
Testing:
Little findings on x-ray, might be able to see a small amount of spurring on acromion or diminished clearance between acromion and humerus (think hooked acromion)
MRI will show inflammation of the bursa
Shoulder: Subacromial Impingement
Tx
Treatment:
NSAIDs,
Steroid injection,
Surgical subacromial decompression if no improvement with conservative tx
(removal of bursa and acromial spurring)
Shoulder: Rotator Cuff Tendon
Strain/ Tear
general
Common complaints
Etiology:
Tear of rotator cuff tendon related to repetitive trauma (think impingement) or acute trauma
Common symptoms/complaints:
Pain with shoulder motion overhead activities
Deltoid pain
Diminished AROM with decreased strength
Shoulder: Rotator Cuff Tendon
strain/tear
PE and testing
Physical exam:
+ Neer, Hawkins, empty can, drop arm
Good PROM, poor AROM
Testing:
MRI, injecting with contrast (arthrogram) will improve visibility of tears, X-Ray will show proximal migration of humeral head
Shoulder: Rotator Cuff Tendon
Srain/ Tear
Tx
Treatment:
Full thickness tears require surgery to prevent osteoarthritis and restore proper function – debridement and repair (8-to-12-week recovery, 6-to-12 month return to normal activity)
Partial thickness tears typically non-operative and managed with physical therapy and cortisone injections
Pearls:
Supraspinatus is most common
Usually distinct injury with young, healthy people and slow, degenerative problem with middle-aged and elderly patients
Shoulder: Labral Tear
general
Etiology:
Tear of the labrum
Tears related to dislocation are often assoc. with Bankart and Hill-Sachs lesions (next slide)
Tears related to pulling from the long head of the biceps tendon are superior labrum, anterior to posterior (SLAP tear)
Common in weightlifters, swimmers, football lineman, gymnasts, wrestlers
Common symptoms/complaints:
Some are asymptomatic, some have pain and instability w/ posterior directed forces, some just have pain, clicking/popping w/ ROM
Shoulder: Labral Tear
PE and testing
Physical exam:
Posterior joint line tenderness
Posterior apprehension test
Testing:
Hill-Sachs & Bankart lesions can be seen on x-rays and MRI (arthrogram is good here)
Will need MRI to diagnose most labral tears, sometimes will need contrast if nothing shows up with simple MRI
Shoulder: Labral Tear
Tx
Treatment:
Sling, rest immediately after injury
First line – NSAID’s, PT, activity modification
Surgical repair for instability and prevent dislocations if related to dislocation
SLAP tear surgical repair is debated, as is PT
Shoulder: Dislocation
general
Etiology:
Humeral head is forced out of the glenoid fossa/ cavity
Common symptoms/complaints:
Diffuse shoulder pain
Edema
Decreased strength and motion
Can usually recall the injury/cause
Shoulder: Dislocation
PE and testing
Physical exam:
Acute pain
Obvious deformity
Diminished ROM
+ Apprehension test
Testing:
X-rays: obvious dislocation and possibly HS & Bankart lesion
MRI is helpful to determine soft tissue damage
Rotator cuff and labrum
Shoulder (Glenohumeral) dislocation
general
Most common major joint dislocation:
- Anterior (95-97%)
- Posterior (2-4%)
May be associated with:
- Fracture dislocation
- Rotator cuff tear
Neurovascular injury (Axillary & Musculocutaneous Nerve)
Hill Sachs deformity
Bankart lesion
Pre-reduction neurovascular exam and x-ray.
Procedural sedation/ intra-articular anesthesia.
Immobilize: Shoulder immobilizer
Shoulder injection (ASPIRATION)
Posterior Approach
- Palpate the posterior lateral edge of the acromion process
- Mark a spot 2cm inferior to this edge
- Inject the shoulder with 10 mL’s of anesthetic targeting the coracoid process
