Femoral Head

• Results from high-energy trauma (e.g. dashboard to flexed knee)
• Usually occurs along with dislocation:
  • Posterior dislocation
    • Fx of inf aspect of femoral head; concomitant sciatic nerve injury
  • Anterior dislocation
    • Fx of anterior femoral head; concomitant vascular injury
• Management
  • Immediate ortho consult; emergent closed reduction of dislocation
