To evaluate the effectiveness of Proximal Femoral Nail Anti-rotation (PFNA) for the treatment of unstable intertrochanteric fracture comparing with Compression Hip Screw (CHS) with Trochanteric Stabilizing Plate (TSP).

With clinical study, 43 patients who were treated surgically for unstable intertrochanteric fractures were retrospectively evaluated. One group was treated with CHS and TSP (Group 1, 22 cases) and the other was treated with PFNA (Group 2, 21 cases). By postoperative radiograph and last follow up radiograph we measured Tip-apex distance, Cleveland index, Lag screw slippage, Neck-shaft angle change and Union time. And By retrospective medical record review, the clinical results were evaluated with the operation time, intraoperative estimated blood loss, amount of drainage, amount of transfusion, walking ability change and complication.

There was a lower operation time, intraoperative estimated blood loss, amount of drainage, amount of transfusion, lag screw slippage and neck shaft angle change in the Group 2 than in the Group 1 (p<0.05).

PFNA showed better results than CHS with TSP in operation time, estimated blood loss, amount of drainage and transfusion, lag screw slippage and neck-shaft angle change.
