What is the best course of treatment for a patient with a fractured shoulder and lung injury?

Management of Fractured Shoulder with Lung Injury

For a patient with both a fractured shoulder and lung injury, immediate priorities are stabilizing the thoracic injury with closed thoracic drainage (tube thoracostomy) for pneumothorax or hemothorax, followed by radiographic assessment of the shoulder fracture to determine if surgical fixation is required based on fracture stability and displacement. 1

Immediate Thoracic Management

Primary Assessment and Intervention

• Most thoracic injuries (90%) can be managed non-operatively with tube thoracostomy, appropriate airway management, oxygen support, volume resuscitation, and adequate pain control 2
• Place closed thoracic drainage immediately for pneumothorax or hemothorax 1
• Adequate pain control is critical—it may be the most effective treatment for chest wall trauma and enables proper respiratory mechanics 2

Indications for Thoracotomy

• Progressive hemothorax despite closed thoracic drainage 1
• Large air leaks in the trachea or severe pulmonary hemorrhage 1
• Severe lung lacerations with persistent dyspnea after tube thoracostomy 1
• Severe tracheal or bronchial injuries causing airway obstruction 1

Lung-Specific Injuries

• Most lung lacerations heal with closed thoracic drainage alone 1
• If laceration is too severe for repair, consider lobectomy or segmentectomy; pneumonectomy carries >50% mortality and should be last resort 1
• For tracheal/bronchial ruptures with mediastinal emphysema: small ruptures can be managed conservatively, but large ruptures require surgical repair if tracheotomy and drainage fail to alleviate dyspnea 1

Shoulder Fracture Assessment

Initial Imaging

• Obtain standard three-view radiographs: AP views in internal and external rotation plus axillary or scapula-Y view 1
• The axillary or scapula-Y view is vital—AP views alone can misclassify dislocations 1
• Radiographs determine fracture classification and guide surgical versus conservative management 1

Advanced Imaging for Fracture Characterization

• CT without contrast is indicated when radiographs show complex or comminuted proximal humeral fractures to fully characterize fracture morphology 1
• CT changes clinical management in up to 41% of proximal humeral fractures by revealing fracture details not visible on radiographs 1
• Three-dimensional CT reconstructions help assess fracture displacement and humeral neck angulation, which affect functional outcomes 1

Shoulder Fracture Management Strategy

Surgical Indications

• Unstable or significantly displaced fractures require acute surgical fixation 1
• Joint instability requires surgical intervention 1
• Patient age, comorbidities, and activity level influence the surgical decision 1

Conservative Management

• 85% of humeral head fractures can be managed non-operatively, particularly in elderly patients 3
• More than 80% of clavicle fractures are managed conservatively 3
• Soft tissue injuries (rotator cuff tears, labral tears) may undergo initial conservative management 1

Critical Exception

• Traumatic massive rotator cuff tears require expedited surgical referral (within weeks, not months) for optimal functional outcomes 1
• Up to 40% of humeral head fractures have associated rotator cuff tears 1

Integrated Management Approach

Sequencing of Care

1. Stabilize thoracic injury first—this takes precedence as it affects oxygenation and ventilation 1, 2
2. Obtain shoulder radiographs once patient is hemodynamically stable 1
3. Determine if shoulder fracture requires immediate surgical fixation or can be managed conservatively 1
4. If both injuries require surgery, coordinate timing with trauma and orthopedic teams 1

Pain Management

• Adequate analgesia is essential for both injuries 2
• Consider regional anesthesia (interscalene block) for shoulder pain if not contraindicated by thoracic injury 4
• Oral analgesics (acetaminophen or NSAIDs) if no contraindications 5

Critical Pitfalls to Avoid

• Do not obtain only AP shoulder radiographs—this misses dislocations and underestimates fracture complexity 1
• Do not delay tube thoracostomy if pneumothorax or hemothorax is present—this is life-threatening 1, 2
• Do not assume all shoulder fractures need immediate surgery—most can be managed conservatively 3
• Do not delay surgical consultation for massive rotator cuff tears—early repair (within 4 months maximum) improves outcomes 1
• Do not underestimate the importance of pain control—inadequate analgesia worsens respiratory mechanics in chest trauma 2

Follow-up Imaging

• If shoulder pain persists despite 3-6 months of conservative management, obtain MRI without contrast to evaluate for soft tissue injuries 1, 5
• MRI is particularly important if rotator cuff tear is suspected based on weakness or impingement signs 6
