Laparoscopic Acetabular Plate Fixation: A Cadaveric Feasibility Study for Technique Development

This technical note describe the feasibility of a reproducible laparoscopic technique for acetabular fracture fixation, focusing on the feasibility of using infra-pectineal and supra-pectineal plates and proper screw placement. A standardized preperitoneal laparoscopic approach was performed on ten adult cadavers. Infra-pectineal and supra-pectineal plates were inserted under laparoscopic control, and screw placement was guided using an eight-zone pelvic classification. Feasibility criteria included exposure quality, implant positioning, operative time, and complications. The procedure was successfully completed in 9 of 10 specimens (90%). Key anatomical landmarks were consistently identified. All implants were positioned as planned. Mean operative time was 115 min (range 90-120), with no major vascular, visceral, or neurological injuries. This technique appears feasible and reproducible and may offer a minimally invasive alternative for selected acetabular fractures, particularly in fragile patients. LEVEL OF EVIDENCE: IV; cadaveric study.
