Background: The elderly are most frequently affected by intertrochanteric fractures, which have a major effect on the medical community and society at large. In 2003, AO introduced the proximal femoral nail anti-rotation device, which was further improved and named proximal femoral nail antirotation II (PFNA II) in 2009. Methods: This study was conducted from December 2020 to August 2022. The 60 cases of proximal femoral nail anti-rotation II-managed intertrochanteric femur fractures were assessed. Results: In the present study, 24 patients (40%) had type IV (Evan’s) fractures. Right hip was involved in 30 patients (50%). Meantime for clinic-radiological union was 20 weeks. There was complication rate of 2.08% as helical blade protrusion and non-union, 2.08% as helical blade protrusion, 2.08% as blade backout, 4.17% as superficial infection and 4.17% as lateral wall fracture. Seven patients expired postoperatively within 3 months while 5 patients lost during follow Up. After a 6-month follow-up, the Harris hip grade was used to evaluate 48 instances. Of these, 8 cases (16.67%) had an excellent score, 29 cases (60.42%) had a good score, 7 cases (14.58%) had a fair score, and 4 cases (8.33%) had a poor score. Thirty-seven of the 48 cases had reached the one-year follow-up mark. Thus, of the 37 patients assessed, 11 cases (29.73%) had excellent Harris hip grades, 19 cases (51.35%) had good scores, 4 cases (10.81%) had fair scores, and 3 cases (8.11%) had poor scores at the end of a one-year follow-up. Conclusions: Even in rural populations, PFN A-II is a better, safer implant with a low rate of complications for treating stable and unstable intertrochanteric femur fractures.
