Short implanted prosthesis and method of making same

A proactive short cervical femoral endoprosthesis comprising,

• a cylindrical body part, said body comprising of an interior chamber, an outer surface of said body is provided with an helicoidal spire for engaging bone and an inner surface of said body delimiting the interior chamber, said chamber has variable lengths, diameters and shapes and communicates with an arborization system of transversal variable diameter orifices;
• said chamber has a middle treaded portion for the insertion of a syringe that delivers orthopedic cement and osteo-stimulating substances through the prosthesis;
• said orifices therethrough extending from the inner chamber to the exterior of said body, said orifices are displaced horizontally with variable angles between 90 and 180 degrees so as to distribute the orthopedic cement and the osteo-stimulating substances;
• at least a portion of said orifice being, in transverse cross-section circular and communicating with the inner chamber of said body;
• a collar located above a threaded portion of the outer surface of said body, said collar having a cylindrical chamber communicating with the interior chamber of the said body and having the main axis aligned with the longitudinal axis of said body;
• a neck with a tronconic shape on which a prosthesis cap is fixed, said neck has an orifice of hexagonal shape for introducing a dynamometric screwdriver so as to fix the endoprosthesis, said orifice is axially aligned with the longitudinal axis of the cylindrical body and collar and communicate with both said body and collar for introduction of orthopedic cement and osteo-stimulating substances;
• said orifice being configured to attach a prosthesis head.
