  • Patent number: 10682161
    Abstract: The invention concerns an inner fixation device for the correction of axial deformities of a limb, for example a long limb, of the type comprising at least one plate (2, 2?) for epiphysiodesis with at least a pair of lobes (3,4) each provided with a through hole (7) to be laterally fixed to a bone portion or to a long bone head. Advantageously, the device (1) comprises one second plate (12, 12?) placed on the opposite side of the bone portion with respect to said at least one plate (2, 2?) and connected to that by at least one rod (15) passing through the bone portion. The rod (15) is extended through the bone in parallel to an epiphyseal plate and it has opposite extremities (16,17) connected to the plates (2,2?; 2,12?) to keep them close to the bone and to stop the bone growth in one central portion of the bone.

  • Patent number: 10667926
    Abstract: An osteotome suitable for cutting through cancellous bone that is holding an orthopaedic implant requiring revision within a cavity of a bone, comprises a cylindrical waveguide connectable to a source of ultrasonic vibrations at its proximal end and a blade having a hollow part-cylindrical cross-section and a cutting edge at its distal tip. The respective longitudinal axes of the waveguide and the blade cross at an angle of about 30°, and the waveguide and blade taper and curve smoothly together where they meet. The osteotome is dimensioned such that a first antinode of the ultrasoncic vibrations is located at a proximal end of the waveguide, a second antinode is located at the distal tip of the blade and a node is located where the waveguide and blade meet. The osteotome cuts readily through cancellous bone when ultrasonically energized.
