Abstract

PURPOSE
This study compared the treatment results between PFN (Proximal Femoral Nail, AO synthes) and newly designed PFNA (Proximal Femoral Nail Antirotation, AO synthes) for proximal femoral fractures.
MATERIALS AND METHODS
Twenty cases, who were treated with PFNA to 20 matched pairs in regard of gender, fracture type, age among who were treated with PFN, were compared retrospectively. The clinical results were evaluated with the operation time, intraoperative bleeding and transfusion. The plain anteroposterior, axial radiograph postoperatively and the measured Cleveland Index and Tip Apex Distance were checked. Bone union, PFNA blade sliding and complications were estimated from the follow up radiograph.
RESULTS
There was a lower operation time and intraoperative bleeding in the PFNA group than in the PFN group but the bone union time and transfusion was similar in both groups. The Cleveland Index and Tip Apex Distance from the postoperative radiographs were similar but sliding and complications were lower in the PFNA cases.
CONCLUSION
PFNA is superior to PFN because the operation time and intraoperative bleeding were diminished, and the complications, such as back out, had decreased.
