Introduction :
The early operative treatment of the peritrochanteric fractures is widely accepted practice and different sliding nail-plate systems, including Gamma Nails (GN) are used in the treatment. The GN was designed to treat unstable trochanteric fractures.
Aim:
The aim of this study was to discuss the results of treatment of unstable peritrtrochanteric fracture of femur in 30 patients treated by fixation by Gamma nail regarding its outcome .
Patients and methods :
The study was based on a total of 30 patients surgically treated for the unstable peritrochanteric femoral fracture in the period between August / 2014 till July /2017. All patients underwent gamma nail osteosynthesis. The average age of the patients was 67.2 years (range 40-81 years) with 13 male patients and 17 female patients. The average operative time was 71.8 min (range 45 -100 min). Clinical and radiographic assessments were performed during follow-up visits at 2 weeks , 6 weeks , 12 weeks and 6 months up to one year.

Results :
According to the final Harris hip score , results were excellent in 7 patients , good in 13 patients , fair in 5 patients and poor in 4 patients while one patient ends with deep infection and non union.
Conclusion :
This study suggests that the gamma nail is an excellent alternative in treatment of unstable peritrochanteric fracture as it gives advantage of closed technique, allows early mobilization and early weight-bearing. It involves lesser perioperative complications.
