abstract: This retrospective, multicentre study has collected 250 cases of fractures of the femur following arthroplasty of the hip and covers a 20 year period from the 25/01/73 to the 30/05/93 (51 peroperative fractures and 199 fractures at some time after arthroplasty). There were 157 women and 93 men whose average age was 73 years for the 199 post operative fractures. The average period between arthroplasty and the fracture is 5 years. A common questionnaire was used by all the centres involved in this study in order to codify conditions of surgery, pre and post fracture X ray examinations and the different treatments and their complications.
