Treatment of Infant Clavicle Fractures
Infant clavicle fractures should be managed conservatively with simple immobilization (sling or no immobilization) and pain control, as they heal predictably without surgery.
Initial Management
For infants with clavicle fractures, nonoperative treatment is the standard of care. The approach includes:
- Immobilization: Use a sling for comfort, though no immobilization is also acceptable (37% of cases in infants 0-2 years required no immobilization) 1
- Pain control: Provide analgesics as needed (acetaminophen or ibuprofen appropriate for age)
- Parental reassurance: Counsel families that prominent callus formation during healing is normal and expected 2
Radiographic healing timeline: Infants and toddlers (0-2 years) demonstrate adequate radiographic healing by 4 weeks (average 20.4 days from injury), making routine follow-up radiographs after this point unnecessary 3
Indications for Orthopedic Referral
EMERGENT Referral (same-day consultation):
- Open fractures
- Posteriorly displaced proximal fractures (risk of neurovascular compromise)
- Associated neurovascular injuries 4
URGENT Referral (within days):
- Greater than 100% displacement
- Shortening >2 cm
- Comminuted fractures
- Unstable distal fractures
- Floating shoulder (combined clavicle and scapular neck fracture) 4
Red Flags Requiring Investigation:
- No history of trauma: Consider malignancy, rickets, or non-accidental trauma (only 1% of cases in one series were reported to child protective services, but this warrants careful evaluation) 1, 2
Clinical Pearls
Most infant clavicle fractures do NOT require orthopedic follow-up. Research demonstrates that if no surgical indications are present at initial assessment, routine clinical or radiographic follow-up is unnecessary 5. The decision to treat operatively is made at the initial assessment, and complications in conservatively managed pediatric clavicle fractures are minimal (2 refractures, no nonunions in a 340-patient series) 5.
Common injury mechanisms in infants: Fall from bed/crib (34%), playful activity (17%), and unspecified falls (16%) 1
Follow-up strategy: A single radiograph at 4 weeks is sufficient to confirm healing in infants. Additional imaging exposes children to unnecessary radiation without changing management 5, 6, 3.
