Abstract :

 Intertrochantric femoral fractures are commen among elderly age group and are associated with substantial morbidity and mortality A wide range of treatement modalities are available for the management and many author have reported that intramedullary devices such as PFN are biomechanically stronger and rigid compared to extramedullary device. PFN has also showed more number of complications like implant failures in the form of screw cutout in case of unstable intertrochantric fractures To improvise in 2003 AO/ASIF introduced PFNA (Antirotation system ) . This study was conducted to understand and analyze the advantages of PFNA over PFN in the management of unstable intertrochantric fractures at Sanjay Gandhi Institute of Trauma and Orthopedics Bangalore between 2012 t–2015 . In all the cases pre operative and post operative clinical evaluation radiological evaluation, assessment regarding operative time, blood loss, fluoroscopy time, time for fracture union, post operative complication are also noted clinical results were evaluated using Harris Hip score The results showed PFNA has better rotation stability with single screw and better functional outcome in treating unstable introchantric fractures
