Background: Intertrochanteric fractures are extracapsular injuries involving the upper portion of the femur, located between the greater and lesser trochanters, and can sometimes extend into the subtrochanteric region. These fractures are common in older adults with advanced osteoporosis, often resulting from low-energy trauma such as minor falls. The Proximal Femoral Nail A2 (PFN A2) is a contemporary intramedullary device designed to provide strong resistance against complications like cut-out and offers improved fixation, making it especially beneficial for patients with osteoporotic bones.
Materials and Methods: In our prospective study, we included 20 patients diagnosed with intertrochanteric fractures. Of these, 12 were female and 8 were male, all of whom underwent surgery using the PFN A2 system within a week of diagnosis. The follow-up period for all patients was at least 6 months. Functional and radiological assessments were conducted at 6, 12, and 24 weeks, with functional outcomes evaluated using the Modified Harris Hip Score
Results: Most patients were in their 60s and 70s, with a higher proportion being female. The average incision length was 6 centimeters, and the mean duration of the surgery was 50 minutes. Fracture union was achieved in all cases within approximately 12 weeks. On average, patients were allowed to begin full weight-bearing activities by the 12th week, following confirmation of union through clinical and radiological assessments. No complications were observed in this study
Conclusion: The PFN A2 system is an effective surgical option for treating intertrochanteric fractures, offering benefits such as shorter surgery duration, minimal blood loss, a smaller incision, early rehabilitation, and a lower risk of implant failure.
