THR Acetabular Fracture

 

Incidence

 

Increased incidence with press-fit component

- especially if under ream

 

Prevention

 

Don't under-ream >1mm

 

In osteopenic bone 

- line to line reaming

- i.e. ream to outer diameter of cup

 

This also avoids leaving gaps at floor 

- very common if under-ream by 2mm
