“Cut-In” Phenomenon – the Rare and Secret Complication of Proximal Femoral Nails – 2 Case Reports and Review of Literature

The use of intramedullary devices to fix intertrochanteric Neck of Femur fractures is an internationally well-established fixation method which demonstrated mechanical and biological advantages, especially in the treatment of unstable fractures patterns. Despite the biomechanically proved advantages of the proximal femoral nails, some complications had occurred over the years. A very rare type of complication was sporadically reported over the last few years, and was termed “Cut-in” or “medial migration” of the blade. We will present our experience of 2 cases with the “cut-in” complication and review the latest literature.
