Unstable intertrochanteric fracture continues to be a challenge for orthopaedic surgeons. Despite high union rate, the functional outcome still tends to be disappointing. Intact lateral wall plays a key role in stabilization of unstable trochanteric fracture by providing a lateral buttress for proximal fragment and its deficiency leads to excessive collapse and varus malpositioning. Patients admitted in with unstable intertrochanteric fractures satisfying the inclusion criteria will be included in the study and will be alternatively allocated into two groups i.e. Group A (will contain patients treated with proximal femoral nail without any augmentation,) Group B (will contain patient treated with proximal femoral nail augmented with additional screw or encerclage wire). In our study, in augmentation group According to Harris Hip scoring system (Modified), excellent results are seen in 10(66.7%), we had good results in 1(7.7%), Fair in 4(26.7%) and no case with poor results. Our results are comparable with other studies. In our study in Control group According to Modified Harris Hip Score excellent result are seen in 6(40%), we had good result in 7(46.7%), Fair in 2(13.3%) and no case with poor results.
