This invention is the multi functional femoral intramedullary nail system having multi locking system which provides union by fixing bones in case of single or multiple fractures of femoral bones except head and neck fractures. The invention includes a nail using the same system for the right or left femur bone by antegrade or retrograde method, and seven locking holes that can apply compression on the proximal side of the nail and provide locking at five different angles and 2 locking holes at the distal end. Unlike conventional nails, the nail also includes a wedge-shaped tip at the distal end that allows easy insertion and locking on the distal supporting screw without using a fluoroscope, thus allowing early movement and loading.
