Cooke and Newman classification

Mr Andrew Murphy and Dr Yair Glick et al.

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
