The Cooke and Newman classification of periprosthetic hip fractures is a modification of the Bethea classification proposed several years earlier.
-
type I
- explosion type fracture, comminuted around the stem of the implant
- the prosthesis is always loose and the fracture is inherently unstable
-
type II
- oblique fractures around the stem
- fracture pattern is stable, but prosthetic loosening is usually present
-
type III
- transverse fracture at the level of the tip of the stem
- the fracture is unstable, but the prosthetic fixation is usually unaffected
-
type IV
- fracture distal to the implant
- the fracture is unstable, but the prosthetic fixation is usually unaffected
