Shoulder disorders & injuries Flashcards
Scapular Fx etiology
- Result of HIGH ENERGY trauma
- Fall, MVA, pedestrian accident, shoulder dislocation
Clinical presentation of a scapular fracture
- Patient holding arm close to their side
- Pain with movement of the upper arm
PE for a scapular fracture
- Ecchymosis
- Swelling/deformity
- Tender to palpation
- Possible crepitus
- Limited ROM
- Check other systems
Scapular Fx diagnostics
- X-ray
- Often these patients are not able to sit upright
- Obtain a chest & shoulder films
- CT
- Any poorly visualized fracture
- Any fracture involving the joint itself
- (glenoid fractures)
Scapular Fx treatment
- Non-operative
- arm in a sling
- Early ROM as tolerated
- Scapular body fx consider admission due to pulmonary contusions
Scapular Fx referral flags
- Displaced fracture >2 mm
- Glenoid fracture (articulating surface)
- Fractures of the neck of the scapula (>30 degrees angulation)
- Acromion fractures with impingement signs
Clavicular Fx etiology
- Most often occurs in children and young adults
- Can result as indirect or direct trauma to the clavicle
Most common shoulder fx in children and young adults
Clavicular fx
Medial clavicle fx’s usually occur due to _____
anterior chest trauma
Distal clavicular fx’s & AC joint disruption are associated with ______
direct blows to the distal clavicle or acromion
Clavicular Fx presentation
- History of an injury
- Outstretched arm or direct impact
Physical Examination of a clavicular fx
- Decreased ROM of the shoulder with pain
over Fx when palpated - Ecchymosis
- Shoulder droop or the patient will hold it
higher - Deformation, tissue tenting
- Feel gliding of the clavicle
- Crepitus possible
- Examine NEUROVASCULAR FUNCTION
How to examine neurovascular function of a clavicular fx
- Distal to the fracture
- Axillary, musculocutaneous, median, ulnar, and radial nerves
- Sensation of the UE’s
- Muscle strength in the UE’s
- Reflexes: Brachioradialis, Biceps, Triceps
- Look for evidence of decreased perfusion
- Skin color changes, diminished pulses, decreased cap refill
Clavicular Fx Diagnostic Testing
- X-ray
- AP view (10° cephalic tilt) for most clavicle fx’s
- CT scan
- For suspected medial clavicle fx’s
Clavicular Fx treatment (outpatient)
- Most mid-shaft fx’s are nonsurgical
- Simple shoulder sling: Worry for skin breakdown, and neurovascular injury
- After ~3-4 weeks start gentle shoulder exercises.
- NSAIDs for pain
- Ice packs initially and then heat once swelling is down
- PT referral if continued decreased ROM
When to reduce/not reduce a clavicular fracture
- Middle third is almost never required: Manipulation can cause neurovascular injury
- Displaced proximal or distal third fx’s requires orthopaedic referral for
reduction - Open fractures, severe displacement with skin at risk, fx’s with neurovascular
injury may require open reduction and internal fixation (ORIF) - Nonunion over 4 months = further evaluation (orthopaedics)
When to send a clavicular fracture to surgery
- Displaced fx of the distal clavicle
- Any proximal clavicular fracture
- Comminuted or severely shortened overall clavicle length: >2cm if over 12 y.o.
- Open fx’s
- Neurovascular involvement
- Skin over fracture is at risk
Clavicular Fx adverse outcomes
- Neurovascular complications (rare)
- Nonunion (common)
- Malunion – visual or palpable bump
- Degenerative arthritis if AC intra-articular involvement
- Surgical repair can have increased chance of:
- Infection
- Hardware issues (loosening or breaking)
- Skin and/or Neurovascular complications.
Humeral Fx etiology
- Usually in children and osteoporotic patients
- High energy trauma in adults
- Fall on outstretched hand that is abducted
- Direct trauma to the proximal humerus
Proximal Humerus Fx’s Clinical Presentation
- History of mechanism of injury that could potentially cause a fx
- fall, osteoporosis, blunt force trauma…
- Severe pain (even with slight movements)
- Swelling
- Find out the dominant hand – may change treatment in pts who use it for
their occupation
Physical Examination for Proximal Humerus Fx’s
- Ecchymosis
- Arm may be rotated
- Neurovascular testing
- Inspect for any lacerations, contusions, or signs of an open fx
Proximal Humerus Fx’s Diagnostic
- Trauma series of the shoulder
- AP, Axillary view, Scapular Y
Proximal Humerus Fx’s treatment
- Minimal displacement = sling with exercise program after 3 weeks and signs of
healing - Early ROM is important to decrease chance of frozen shoulder
- PT with humeral fracture protocols your clinic has developed
When to refer Proximal Humerus Fx’s to surgery
- Surgical treatment if any part is angulated >45° or >1 cm displacement
- Displacement of the greater tuberosity > 0.5cm needs surgical consult
- Any displaced 2-part fractures
- All 3 and 4-part fractures
- Any neurovascular involvement
