The invention relates to a device that is used to perform surgery to reduce multiple femoral diaphyseal and intertrochanteric fractures, hip fractures and/or diaphyseal fractures. The inventive device comprises a grooved centro-medullary nail which is applied with or without an angular plate or with or without a diaphyseal plate. Said grooved centro-medullary nail comprises a body (15) consisting of at least one groove (16) which enables the positioning of the tightening screws (30). Moreover, said device comprises an extension piece (18) which can be connected to the nail (10) in order to increase the dimensions thereof and ensure that said nail can penetrate the medullary canal of the fractured bone. The aforementioned extension piece can be removed from the nail (10) once said nail been inserted sufficiently into the medullary cavity to enable the anchoring of the angular plate. Furthermore, said extension can be connected to the nail (10) once again in order to extract same from the medullary cavity. In addition, the inventive device comprises an angular plate which is used to support the fractured diaphyseal and epiphyseal portions.
