title: Results of an operative policy in the treatment of periprosthetic femoral fracture.
abstract: OBJECTIVE
  To determine the clinical outcome of patients with periprosthetic femoral fractures treated operatively.
  
  
  METHODS
  Retrospective analysis from 1986 to 1993.
  
  
  METHODS
  Edinburgh Orthopaedic Trauma Unit, Edinburgh, Scotland.
  
  
  METHODS
  Forty-five patients identified from a computer database as being admitted to the Edinburgh Orthopaedic Trauma Unit with periprosthetic femoral fractures.
  
  
  METHODS
  Clinical outcome grade (good, fair, poor) dependent on integrity of fixation, refracture rate, and ability to perform activities of daily living analyzed against age, type of fracture, prosthetic alignment, loosening, and method of fixation.
  
  
  RESULTS
  Type I fractures were more common in uncemented or loosely cemented prostheses, whereas type II fractures occurred predominantly in securely cemented prostheses. Type I fractures treated by revision had the poorest results. Outcome in type II fractures was equally good whether treated by internal fixation or by revision. Age, loosening, and prosthetic alignment did not influence outcome. The mortality rate in this series was 20%.
  
  
  CONCLUSIONS
  If a prosthesis is loose, it should be revised, or treatment varies with fracture and prosthetic type. In type I fractures, an uncemented stem may be revised to a cemented one; however, a securely cemented prosthesis probably is better when fixed internally. Type II fractures should be fixed internally because there is less operative insult. Type III fractures probably are not related to the prosthesis and should be fixed internally according to normal practice. The results of an operative policy compare well with the results of conservative management and avoid the problems of long-term immobilization.
