Hip dislocation

Background

• Orthopedic emergency; reduction should occur w/in 6hr
• High-energy trauma is primary mechanism
• Types:
  • Posterior
    • 90% of hip dislocations
    • Acetabular fractures may result as well
  • Anterior
    • 10% of hip dislocations
    • Can be superior (pelvic) or inferior (obturator)
    • Neurovascular compromise is unusual

Clinical Features

• Posterior Dislocation
  • Extremity is shortened, internally rotated, and adducted
• Anterior Dislocation
  • Extremity is abducted and externally rotated

Imaging

• Hip AP and lateral views
• Also consider Judet views or CT to evaluate acetabulum (esp for posterior dislocation)

Management

• Reduce
