Hypothesis: Inflatable intra medullary femoral nailing is superior to DHS in terms of blood loss, operative complications and postoperative rehabilitation in the management of pertrochanteric femur neck fractures.

patients with pertrochanteric fractures of the femur will be randomly assigned to one of 2 groups.

group 1 will undergo internal fixation using a DHS device. group 2 will undergo internal fixation using an inflatable intramedullary femoral nail device post operative care will be the same including DVT prophylaxis, early mobilization.

weight baring will be aloud in cases of a stable fracture (EVANS 1-3) non weight bearing until callus bridge in patients with unstable fractures (EVANS 4-6)

outcomes: death within first year

postoperative complications length of hospitalization time to mobilization functional score reontgenic evaluation
