Periacetabular fracture

Periacetabular fractures are often difficult to treat. They can happen intraoperatively in hip prosthetic replacement during the cup insertion (more often in press-fit cups), excessive acetabular reaming or they can occur after time and in stable cups due to adequate trauma.

For the correct treatment we have to know

  • amount of bone loss?
  • Column defects ? and which:
    • anterior 
    • posterior
    • central (lateral border)
    • pelvic discontinuity (all three columns)
  • previous surgery approach

To guarantee a sufficient stability of the acetabular cup, we need 2 intact or stable columns; mainly the posterior column
