CPC A61B 17/744 (2013.01) [A61B 17/74 (2013.01)] | 12 Claims |
1. A multi-component femoral reinforcement prophylactic device adapted to be placed into a surgically excavated upper portion of a human femur rotatably connected to one side of the human pelvis, an upper portion of the femur including an integrally formed inwardly extending neck terminating in an integrally formed generally ball shaped head constrained within a corresponding outwardly extending socket on the pelvis, the femoral reinforcement device comprising at least two separate and distinctly shaped implant components:
a downwardly curved implant component adapted to be inserted downwardly and inwardly into a first correspondingly shaped excavation extending downwardly from the intertrochanteric region and into an intramedullary portion of the femur, said downwardly curved implant component having a first non-circular cross section for restricting rotation relative to the correspondingly shaped excavated portions of the femur into which the downward curved implant component is being inserted; and
an upwardly curved implant component adapted to be inserted upwardly and inwardly into a correspondingly shaped excavation extending upwardly from the intertrochanteric region through the neck and into the ball-shaped head of the femur, said upwardly curved implant component having a second non-circular profile for restricting rotation of the second implant component relative to the correspondingly shaped excavated portions of the intertrochanteric, neck and head portions of the femur into which the upwardly curved implant component is being inserted,
wherein the upper end of the downwardly curved implant component and the lower end of the upwardly curved implant component comprise respective integrally formed mating portions, the mating portions each comprising up to two components and for securing the two implant components from rotation relative to each other once both implant components have been inserted into the intertrochanteric region, and wherein the downwardly curved implant component further comprises means for coupling the downwardly curved implant component to an upper end of a femoral retrograde intramedullary fixation nail that is subsequently inserted upwardly into the intertrochanteric region from the lower end of the human femur.
