TO EVALUATE THE EFFICACY OF KICK STAND SCREW IN FIXATION OF SUBTROCHANTERIC FEMORAL FRACTURES USING CONTRALATERAL REVERSED DISTAL FEMORAL LOCKING PLATEPROSPECTIVE SINGLE CENTRIC STUDY

Abstract

PURPOSE- All type of plates when used for proximal femur fractures always has chances of mechanical failure due to lack of strength of the construct, but addition of ‘kick stand screw’ has some effects on stability of the construct. Aim of our study is to evaluate the efficacy of kick stand screw in fixation of subtrochanteric fractures using contralateral reversed distal femoral locking plate. METHOD- 30 patients of subtrochanteric fractures fixed using contralateral reversed distal femoral locking plate. N(1st)=15 fixed without kick stand screw and other N(2nd)=15 fixed using kick stand screw. Calcar screw( Kick Stand Screw) is placed to support calcar region (inferior to the center in AP view and central in Lateral view). In other group screws are placed as oriented in screw holes. Outcome was assessed using Harris Hip Score and VAS score and change in the neck shaft angle is also followed. RESULT- Union rate was 80% in 1st group as compare to 94% in second group. Mean Harris hip score at the one year follow up was 71.2 in 1st group as compare to 89.2 in 2nd group. Mean Visual analogue scale was 3.2 in first group as compare to 1.6 in second group at final follow up. Mean neck shaft angle at final follow-up was 120 degree in first group as compared to135 degree in second group. Complication- 1st Group of patients had three failures 2 in the form of screw break down and one in the form of plate bending, all three lend up in to varus deformity but the 2nd group had only one failure in the form of plate bending. CONCLUSION-In our study cases in which kick stand screw was used they showed better mechanical strength and gave better clinical results. So in proximal femur fractures including subtrochanteric fracture fixation ‘kick stand screw’ must be used.
