Park, Won, and Han: Treatment of Intertrochanteric Fractures Using Targon Proximal Femoral Nails



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.


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.


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.
