Abstract          Introduction: Subtrochanteric femur fractures have demanded special consideration in orthopaedic traumatology, given the high rate of complications associated with their management. 10%–34% of all hip fractures occur in the subtrochanteric region. Purpose of the study: To compare the clinical outcome of Seinsheimer type IIB and type IIIA subtrochanteric fractures treated with PFN versus LCP – PF. Materials and Method: A prospective study of 40 patients with Seinsheimer type IIB and type IIIA subtrochanteric fracture among which 20 were treated with Proximal Femoral Nail and 20 with Proximal Femoral-Locking Compression Plate at two Hospitals attached to J.J.M Medical College Davangere, Karnataka, India between June 2014 to October 2015.. At final follow up results were assessed with Modified Harris Hip score. Result: In the PFN group, 9 patients (45%) showed excellent outcome, 9 patients (45%) showed good outcome and 2 patients (10%) showed fair outcome. Among the PF-LCP group, 12 patients (60%) showed good outcome, 4 patients (20%) showed fair outcome and 04 patients with poor outcome. Conclusion: Proximal Femoral Nail for subtrochanteric fractures has better results compared to Locking Compression Plate-proximal femur with less failure rates and restoring better hip biomechanics.
