54
Clavicle Fractures

• Diagnosis
• History physical
• X-ray AP axillary views, AP with 45 tilt
• CT for proximal distal clavicle fractures

55
Clavicle Fractures

• Surgery
• Open fracture
• Neurovascular compromise
• Displacement gt shaft width
• Healed clavicle lump not desirable
• Floating shoulder (concurrent scapular neck
  fracture)

56
Clavicle Fractures

• Conservative
• Rest
• Immobilization
• sling proven BETTER than fig-8
• Pain control, NO NSAIDs
