Comparative study of PFN vs PFNA 2 in intertrochanteric fractures: A randomised control trial

Introduction: As the life expectancy increases due to improved medical facilities, it leads to increased incidence of intertrochamteric fracture. The intertrochanteric fractures can be managed by conservative methods or by surgery. PFN comprise of an intramedullary nail with two screws of which one is the lag screw settling the fracture as it collapses and other is antirotation screw giving the rotational stability. PFN comprise of an intramedullary nail with two screws of which one is the lag screw settling the fracture as it collapses and other is antirotation screw giving the rotational stability. Aim of our study is to analyze both the intramedullary devices as functional outcome and implant related complications. Material and Method: A prospective, randomized, comparative study of 60 patients. This study was conducted in Patna Medical College and Hospital, Patna, Bihar, between June 2017- June 2019 for two Years. Conclusion: From the study we concluded that the PFNA2 reduces the surgery time, blood loss, and image shots number as compared to PFN. As the union rate is more with PFNA2, the functional outcome is significantly better with PFNA2 than PFN. Implant related late complication is more with PFN which was markedly reduced with PFNA2.
