Less invasive stabilisation system (LISS) for the treatment of periprosthetic femoral fractures: a 3-year follow-up.

Recent publications have reported encouraging results with a locked plating system in the management of periprosthetic femoral fractures. However, data on mid- or long-term functional outcome is not available. Here we report on the mid-term functional outcome of 16 patients with a periprosthetic femoral fracture following total hip arthroplasty managed with the LISS-system at a 3-year follow-up. Functional outcome was measured using the Harris Hip score and the Karnofsky activity index. The Harris Hip score and the Karnofsky activity index averaged 79.5 points and 81%, respectively. There were a total of two major complications due to screw pullout representing a complication rate of 13%. This series suggests that the management of periprosthetic femoral fractures with the LIS-System results in a good mid-term functional outcome.
