Treatment for Displaced Clavicle Fracture
For adults with displaced midshaft clavicle fractures, surgical treatment is recommended when shortening exceeds 1.5cm or displacement is greater than 100% (no cortical contact), as this approach provides higher union rates, better early functional outcomes, and reduces the risk of symptomatic nonunion from 15% to approximately 3%. 1
Initial Assessment and Decision Algorithm
Obtain upright radiographs to accurately assess displacement, as supine films underestimate the true degree of displacement. 1
Key Decision Points:
Surgical indications include: 1
- Shortening exceeding 1.5cm
- Displacement >100% with no cortical contact between fragments
- Displaced lateral fractures with coracoclavicular ligament disruption
Conservative management is appropriate for: 1
- Non-displaced or minimally displaced fractures
- Fractures without significant shortening
Surgical Treatment Options
When surgery is indicated, you have two equivalent options:
Plate fixation: 1
- Use manufacturer-contoured anatomic clavicle plates (lower rates of implant removal/deformation)
- Anterior inferior plating preferred over superior plating (lower hardware removal rates)
- Better for comminuted fractures
Intramedullary nailing: 1
- Provides equivalent long-term outcomes to plate fixation
- Similar complication rates
- Suitable for simple fracture patterns
Conservative Management Protocol
For non-displaced fractures: 1
- Use a simple sling (NOT figure-of-eight brace)
- Slings are the preferred immobilization method per AAOS guidelines
Do NOT use low-intensity pulsed ultrasonography (LIPUS) - it does not accelerate healing or reduce nonunion rates. 1
Evidence Supporting Surgical Intervention
The shift toward surgery for displaced fractures is based on:
- Nonunion rates: Conservative treatment of widely displaced fractures results in nonunion rates up to 15%, compared to approximately 3% with surgery 2, 1
- Early functional recovery: Surgery provides better patient-reported outcomes in the first year and faster return to work 2, 1
- Symptomatic malunion: Conservative treatment leads to malunion rates of 11.3% versus 1.2% with surgery 3
Important caveat: Long-term patient-reported outcomes (beyond 1 year) are similar between surgical and nonsurgical approaches, so the primary benefit of surgery is faster recovery and reduced risk of nonunion/symptomatic malunion. 1
Special Populations
Adolescents (≤18 years): 4
- Nonsurgical management is generally preferred as primary treatment
- Surgery has not demonstrated significant benefits over conservative management in this age group
- High rates of subsequent hardware removal procedures
- Surgical indications limited to: open fractures, polytrauma requiring early mobilization, or severely displaced fractures with >1.5cm shortening
Young children (under 2 years): 5
- Simple sling immobilization
- Surgery not indicated
- Must evaluate for non-accidental trauma if no clear fall history
Risk Factors for Poor Outcomes
Smoking significantly increases nonunion rates and leads to inferior clinical outcomes - counsel patients on cessation. 1
Postoperative Management
Sling use and progression: 1
- Discontinue sling by 4 weeks for routine activities
- Avoid lifting, pushing, or pulling until 4 weeks
- Full weight-bearing activities allowed at 8-12 weeks based on radiographic healing
Rehabilitation protocol: 1
- Cryotherapy immediately postoperatively through first week
- Isometric strengthening at 4-6 weeks (non-weight-bearing)
- Combined strength and neuromuscular control exercises at 6-12 weeks
- Confirm >90% strength symmetry and full pain-free ROM before return to heavy labor or contact sports
Common Pitfalls
Surgical complications to anticipate: 1, 3
- Hardware removal for discomfort (10.2% of surgical patients)
- Infection (3.2% in surgical group only)
- Wound dehiscence
Conservative treatment complications: 1, 3
- Symptomatic malunion (11.3%)
- Symptomatic nonunion (11.6%)
- Cosmetic deformity
- Longer time to return to work
Urgent Orthopedic Referral Criteria
Refer urgently for: 1
- Displacement >100% (no cortical contact)
- Open fractures
- Neurovascular compromise
