[Exploration of the treatment for the periprosthetic femoral fractures].
OBJECTIVE
To investigate the clinical value of the different managements of periprosthetic femoral fractures (PFF). A retrospective study of 16 cases with PFF fixed respectively with cable, plates and screws, encircling device and altered long stem prosthesis was undertaken.


RESULTS
Clinical and functional results were followed-up from 4 to 14 months with an average of 6 months. All the fractures were healed with excellent functional recoveries. Three of these cases scored above 90; 9 cases scored 80 to 89; 3 cases scored 70 to 79; and 1 case scored 63 according to the functional evaluation. The success rate of these treatments was 75%.


CONCLUSIONS
Different types of PFF should be treated with different methods. Cable with stainless steel cerclage was used for fissure fracture from the femoral neck to lesser trochanter; a smaller type of prosthesis was grafted and then fixed with the cable for complete fissure fracture; longer prosthetic stem graft replacement accompanied by cable fixation, and locked nailing or encircling devices for distant part of the graft, were recommended for fractures happened from inferior edge of lesser trochanter to superior margin of narrowed segment of femoral stem. Steel plate or encircling devices fixation with bone graft is suitable for fractures occurred on inferior part of narrowed segment of femoral stem marrow.
