Avascular Necrosis of the Femoral Head Following Intramedullary Nailing of a Femoral Shaft Fracture in a Skeletally Mature Adult: A Case Report

Avascular necrosis (AVN) of the femoral head is a well-documented complication that occurs following femoral neck fractures in both adults and pediatrics. Incidence of AVN following intramedullary nailing (IMN) for femoral shaft fractures is relatively rare. We are reporting an exceptional case of a 28-year-old skeletally mature adult, with no risk factors, who developed stage 3 AVN following trochanteric entry-point IMN for a traumatic femur shaft fracture. Our case contributes to the existing literature by adding to the limited number of reported cases available. In addition, it emphasizes the importance of observation and anticipation for such complications and shows the need for further studies to understand the relationship between this modality of treatment and the development of AVN of the femoral head.
