Johansson classification

The Johansson classification of periprosthetic hip fractures was the first classification system proposed and is the simplest. It is based on the level of fracture in relation to the prosthesis.

  • type I: fracture proximal to tip of prosthesis with stem still in contact with medullary canal
  • type II: fracture extends distal to tip of prosthesis, with dislodgement of stem from medullary canal of distal fragment
  • type III: fracture entirely distal to tip of prosthesis

Other classification systems for periprosthetic hip fracture include:
