Subtrochanteric fractures pose a therapeutic challenge to the surgeons.With the advent of proximal femoral nails, most of the cases are treated with nailing.Newer nails like proximal femoral nail ant-rotation (PFNA) require the blade to be directly hammered into the bone compared to older nails where the screws are drilled and tapped before insertion.We report one such case in a middle aged female that had intraoperative lateral cortex blowout during PFNA blade insertion in a sclerotic bone.This occurrence to the best of our knowledge is unreported in literature.It is therefore imperative to consider the quality of bone before a decision is made on the implant chosen.
