Area of Science:

  • Orthopedic Surgery
  • Minimally Invasive Surgery
  • Surgical Anatomy

Background:

  • Displaced acetabular fractures typically necessitate open surgical interventions.
  • Current minimally invasive approaches may have limitations in surgical access.

Purpose of the Study:

  • To evaluate a laparoscopic approach for preparing the anterior acetabular column and quadrilateral plate.
  • To assess the feasibility of a minimally invasive osteosynthesis for acetabular fractures.

Main Methods:

  • A step-by-step laparoscopic preparation and anatomical demonstration in a human cadaver.
  • Modular plate osteosynthesis of the anterior column and quadrilateral plate using standard laparoscopic instruments.

Main Results:

  • The laparoscopic preperitoneal preparation provides enhanced range of motion for surgical instruments.
  • Successful demonstration of minimally invasive osteosynthesis of the anterior acetabular column.

Conclusions:

  • Laparoscopic preperitoneal preparation is a viable technique for acetabular fracture surgery.
  • This approach offers advantages over the total extraperitoneal approach regarding instrument maneuverability.
  • Further development of specialized tools and implants is needed for widespread clinical adoption.
