Anatomy in Surgical Education

Knowledge of anatomy/exposure essential

Time devoted to anatomy decreasing

Interns lack adequate knowledge

Cadaveric dissection is irreplaceable

cadaver based education
Cadaver-Based Education
  • Ideal model for surgical skills training
  • Support basic and complex operations
  • Superior to other models / simulators
  • - Realistic
  • - Provides haptic feedback
  • - Representative surgical anatomy
specific aims
Specific Aims
  • Describe UCLA Surgery anatomy program
  • Assess resident attitudes toward program
