The Gamma nail is used for the treatment of trochanteric and subtrochanteric fractures because it pravides the theoretical advantage of a load-sharing femoral component. We report the postoperative results of DYAX-A (titanium gamma nail) for trochanteric and subtrochanteric fractures in 24 cases from October 2002 to July 2003 and results of comparison between reamed nailing and unreamed nailing.
We found no difference in blood loss, postoperative patients' mobility, and fracture union. But operating time were shorter in the unreamed nailing cases,in which the one step conical reamer was used. The unreamed procedure is useful, especially when shorter operative time and less blood loss is desired.
There were few operative and postoperative complications, but cut-out occurred in one case. To avoid cut-out, it is necessary to master the appropriate surgical techniques and insert the lag screw in an appropriate position.
