Abstract:
BACKGROUND:Less Invasive Stabilization System (LISS) has been shown to hold the same biomechanical strength to proximal femoral nail anti-rotation.OBEJCTIVE:To investigate the safety and effectiveness of the reversed LISS plates for senile femoral intertrochanteric fractures.METHODS:Thirty elderly patients with femoral intertrochanteric fractures were treated with reversed LISS plates.The operation time,incision length and total blood loss (intraoperative plus volume of drainage 1 day postoperative) were recorded.Physiologic and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) and modified POSSUM scoring systems were used to predict the incidence of complications and mortality,and then the real incidence of complication and mortality was compared to evaluate the safety of reversed LISS plates.The clinical effectiveness was evaluated by fracture healing time and Harris scores at the last follow-up.RESULTS AND CONCLUSION:(1) The incidence of complications showed significant difference between predicted (46.05％) and real (13.3％) results (P=0.05),but the mortality did not differ significantly between predicted (3.93％) and real (0％) results (P=1).(2) The fracture healing time was 21-32 weeks,and the excellent and good rate in Harris scores at the last follow-up was 83.3％.(3) These results indicate that the reversed LISS plates are easy to operate,safe and obtain good efficacy in the treatment of senile femoral intertrochanteric fractures.
