Abstract

Purpose

To investigate the clinical and radiologic outcome after treatment of intertrochanteric fractures of femur using targon proximal femoral nails (PFN).

Materials and Methods

One hundred fifty-five cases of intertrochanteric fracture who were treated with targon PFN from August 2004 to June 2010 were included. There were 54 men and 101 women with a mean age of 74.1 years at the time of surgery. There were 97 cases of stable fracture and 58 cases of unstable fracture. Operation time, frequency of transfusion, weight-bearing time, ability of activity after operation, and complications were all clinically investigated. Also, the average sliding of a lag screw and average union period were radiologically investigated.

Results

The average operation time was 64 minutes and transfusion was required in 43 cases(27%). The average weight bearing time was 4.4 days. In 96 cases(62%), the pre-injury activity level was recovered. The average slide of the lag screw was 5.6 mm and the average union period was 10 weeks. There were 6 cases (3.8%) of complications including 3 cases antirotation pin cutout and 3 cases of periprosthetic fracture.

Conclusion

The treatment of intertrochanteric fractures using targon PFNs showed a satisfactory clinical outcome and a lower radiological complication rate.

(B) Immediate postoperative radiograph shows well reduced fracture by using Targon® Proximal Femoral Nail. (C) Postoperative 1 year hip AP radiograph shows solid union of fracture and 10 mm sliding of lag screw without lateral protrusion of lag screw.
