A comparative study between proximal femoral nail and proximal femoral nail antirotation in treatment of unstable inter trochanteric fractures in elderly

Introduction: Unstable intertrochanteric fractures are those intertrochanteric fractures with loss of posteromedial buttress, comminution of greater trochanter, reverse obliquity, intertrochanteric extension to neck. PFN and PFN A are two implants which have been commonly used to stabilize these fractures. Each of these implants has its own advantages and disadvantages. Our study was undertaken in an attempt to compare these two types of Intra-medullary devices. Material and Methods: A prospective follow up study was carried out at Dr. D.Y. Patil medical college, Pimpri, Pune from June 2017 to December 2018 with 25 being the sample size, randomized into 2 groups to undergo CRIF (Closed Reduction and Internal Fixation) of trochanteric fractures with either a standard PFN or PFNA. Out of the 25 patients, 13 underwent fixation with PFN (proximal femoral nail) and the remaining 12 with PFNA (proximal femoral nail antirotation) and follow-up was done at 06 weeks, 12weeks, 24weks and 1year. Conclusion: From the study we can reason that, when the fracture is united, functional result is identical in the both category. Be that as it may, contrasted with PFN, utilization of PFNA altogether lessens the operative span, measure of blood loss and number of intraoperative fluoroscopic imaging and certain implant related complications and furthermore the duration of stays in the tertiary care center.
