Clavicle X-Ray: Radiographic Views and Management
For suspected clavicle fractures, obtain standard anteroposterior (AP) and 20° cephalic tilt views initially, with consideration for additional orthogonal views (45° cephalic and 45° caudal tilt) when displacement is uncertain or surgical decision-making is needed.
Radiographic Imaging Protocol
Standard Initial Views
- AP view and 20° cephalic tilt view comprise the standard trauma series for clavicle fractures 1
- These two views are adequate for most initial evaluations and treatment planning
Enhanced Imaging for Surgical Decision-Making
Adding orthogonal views (45° cephalic tilt and 45° caudal tilt) significantly improves surgical decision-making, with studies showing:
- 26% of cases changed from nonoperative to operative management when additional views were obtained 2
- Improved intraobserver reliability (R = 0.76 vs 0.64 for 2-view series) 2
- Better visualization of anterior-posterior displacement 2, 3
When to Use Advanced Imaging
- CT scanning is indicated when:
Upright vs Supine Radiographs
Routine upright clavicle radiographs rarely alter management and should be reserved for case-by-case consideration rather than routine use. Recent evidence shows only 1.3% of patients had management changed based on upright films, with no significant difference in displacement measurements between supine and upright views (average change 4.5 mm, P=0.71) 6.
Management Algorithm Based on Fracture Pattern
Immediate Orthopedic Consultation Required
- Open fractures
- Posteriorly displaced proximal fractures (risk of neurovascular injury)
- Associated emergent injuries (vascular compromise, pneumothorax, brachial plexus injury) 1
Urgent Orthopedic Referral (Within 1-2 Days)
- Displacement >100%
- Shortening >2 cm
- Comminuted fractures
- Unstable distal fractures (Neer type II and V) 1, 7
- Floating shoulder (combined clavicle and scapular neck fracture)
Nonoperative Management with Outpatient Follow-up
Minimally displaced or nondisplaced fractures without neurovascular injury can be safely managed with sling immobilization 1:
- Simple sling (not figure-of-8, which offers no advantage)
- Multimodal analgesia
- Activity restriction
- Outpatient orthopedic follow-up within 1-2 weeks
Surgical vs Nonsurgical Treatment for Displaced Fractures
For displaced midshaft clavicle fractures in adults, surgical treatment provides higher union rates and better early patient-reported outcomes, though long-term outcomes are similar 8.
Evidence Supporting Surgery
The 2023 AAOS guidelines provide a strong recommendation that surgical treatment of displaced clavicle fractures results in:
- Higher union rates (nonunion risk 15% with conservative treatment vs <5% with surgery)
- Better short-term functional outcomes (Constant and DASH scores)
- Faster return to work (particularly relevant for active adults)
- Reduced symptomatic malunion rates 8
Key Consideration
Long-term patient-reported outcomes (beyond 1 year) are similar between surgical and nonsurgical treatment, making both valid options depending on patient factors 8. The decision should weigh:
- Patient age and activity level
- Occupation and need for rapid return to work
- Cosmetic concerns
- Surgical risks vs nonunion/malunion risks
Pediatric Considerations
- Generally managed conservatively regardless of displacement
- Adolescents >9 years (girls) or >12 years (boys) follow adult algorithms 1
Common Pitfalls
Missing subtle fractures on standard radiographs: Maintain high clinical suspicion and obtain CT if radiographs are negative but clinical examination suggests fracture 4
Underestimating displacement: Standard 2-view series may miss anterior-posterior displacement; consider 4-view series when surgical decision is borderline 2, 3
Routine use of upright films: These add minimal value and should not be routine 6
Distal clavicle fractures: Require special attention to coracoclavicular distance and ligament integrity; increased CC distance indicates need for CC stabilization 7
Assuming all pediatric fractures heal well: Adolescents approaching skeletal maturity should be evaluated using adult criteria 1
