How should acute clavicle pain be evaluated and managed?

Evaluation and Management of Acute Clavicle Pain

Start with plain radiography of the shoulder/clavicle as your initial imaging study—this is the standard of care for any acute shoulder or clavicle pain. 1

Initial Evaluation

Imaging Approach

• Obtain standard radiographs first including anteroposterior (AP) views in internal and external rotation plus an axillary or scapula-Y view 1

  • These views are essential because AP views alone can miss acromioclavicular joint injuries and dislocations 1
  • Radiographs should be performed upright when possible, as supine imaging can underrepresent malalignment 1

• If radiographs show a clavicle fracture, proceed to CT shoulder without IV contrast to characterize the fracture pattern, assess displacement, comminution, and shortening 1

  • CT provides superior detail of fracture planes and is the appropriate next step for surgical planning 1

• If radiographs are normal but clinical suspicion remains high for occult fracture, order either CT shoulder without IV contrast or MRI shoulder without IV contrast 1

  • CT identifies subtle nondisplaced fractures with high spatial resolution 1
  • MRI demonstrates bone marrow edema from trauma and can identify associated soft tissue injuries 1

Management Based on Fracture Pattern

Indications for Emergent Orthopedic Consultation 2

• Open fractures
• Posteriorly displaced proximal clavicle fractures
• Associated neurovascular injuries

Indications for Urgent Orthopedic Referral 2

• Fractures with >100% displacement
• Shortening >2 cm
• Comminuted fractures
• Unstable distal clavicle fractures
• Floating shoulder injuries

Displaced Midshaft Clavicle Fractures in Adults

Surgical treatment achieves higher union rates and better early patient-reported outcomes compared to nonoperative treatment, though long-term outcomes are similar—both options are valid. 1

• Surgical fixation provides faster time to union, which matters for patients needing rapid return to work or sport 1
• The main benefit of surgery is reducing nonunion risk 1, 3
• Key clinical pearl: If pain shows minimal or no decrease from week 2 to week 4 after injury (VAS ratio >0.6), the patient has an 18-fold increased risk of symptomatic nonunion and should be considered for surgical intervention 3

Nondisplaced or Minimally Displaced Fractures

Treat conservatively with sling immobilization, pain management, and early range-of-motion exercises as tolerated. 2, 4, 5

• Use sling for comfort only—not strict immobilization 2, 4
• Initiate physical therapy as pain allows 4
• Most heal without operative intervention 2, 5

Pain Management

Multimodal Analgesia

• Oral analgesics (NSAIDs, acetaminophen) as first-line 2
• Topical analgesics for localized pain 6
• Consider ultrasound-guided clavipectoral plane block for severe pain—this can provide complete pain relief for up to 36 hours in the emergency department setting 6

Pediatric Considerations

• Manage pediatric clavicle fractures conservatively with sling and supportive care 2, 4
• Adolescents >9 years (girls) or >12 years (boys) should be treated using adult algorithms 2

Common Pitfalls to Avoid

• Don't rely on AP views alone—you will miss AC joint injuries and dislocations without axillary or scapula-Y views 1
• Don't assume all displaced fractures need surgery—both operative and nonoperative approaches are valid, with similar long-term outcomes 1
• Don't ignore persistent pain at 4 weeks—this is a red flag for potential nonunion requiring surgical consideration 3
• Don't order CT as initial imaging—radiographs are sufficient to identify displaced fractures and malalignment, which are the primary acute concerns 1

Follow-Up

• Arrange orthopedic follow-up within 1-2 weeks for all clavicle fractures 2
• Monitor pain trajectory closely in the first month—lack of improvement suggests healing problems 3
• Radiographic union typically occurs by 6 months 3, 5
