摘要： Extrakorporal längenverstellbares Implantatsystem umfassend - eine Implantatkomponente (1) für eine implantierbare Prothese, die zur Befestigung an einem zu verlängernden Knochen (90) ausgebildet ist und eine Verstelleinrichtung (2) aufweist mit zwei gegeneinander verschieblichen Befestigungsteilen (21, 22), von denen jedes an einem Teil des zu verlängernden Knochens (90) anzuordnen ist, wobei die Verstelleinrichtung (2) ausgebildet ist, die zwei gegeneinander verschieblichen Befestigungsteile (21, 22) zu distrahieren, und ein Antriebselement (3) mit einem drehbeweglich angeordneten Permanentmagneten und ein Getriebe (4) umfasst, das eine Drehbewegung des Permanentmagnets in eine distrahierende Längsbewegung der Verstelleinrichtung (2) umsetzt; sowie - eine extrakorporale Antriebseinheit (7, 7', 7") für das Antriebselement der Implantatkomponente(1). Die extrakorporale Antriebseinheit (7, 7', 7") weist einen drehbar gelagerten extrakorporalen Magnetring (8) mit einem Innenraum (80), der zur Aufnahme des zu verlängernden Knochens (90) mit der Verstelleinrichtung (2) ausgebildet ist, und eine Betätigungseinrichtung (75) auf, die dazu ausgebildet ist, den extrakorporalen Magnetring (8) in seiner Ringebene zu rotieren, wobei der extrakorporale Magnetring (8) in Permanentmagnetbauweise ausgeführt ist und in seinem Innenraum ein gerichtetes statisches magnetisches Feld aufweist, das ringfest ist, und der extrakorporale Magnetring (8) mechanisch von der Betätigungseinrichtung (75) rotiert ist. Die Erfindung erreicht so eine Erhöhung der Verstellsicherheit bei gleichzeitiger Vereinfachung der Antriebseinheit, und wird so laien- und patiententauglich.

摘要： The present invention relates to an implantable bone elongation device including an inner rod defining an internal cavity housing a rotational actuator having an output shaft connected to a lead screw disposed at the end of the inner rod and in threaded engagement with a threaded inner surface of an outer rod. Rotation of the lead screw converts rotation motion into linear motion resulting in telescopic movement of the outer rod relative to the inner rod. Rotational motion is converted into linear motion by components disposed in a parallel configuration thereby minimizing the overall length of the bone elongating device while maintaining a maximum stroke length. In various embodiments, additional components, such as electronic circuit boards, electrical power supply or battery power source, may be housed within the internal cavity formed by the inner rod.

摘要： A method of evaluating a bone fracture reduction includes imaging, intraoperatively, a fractured bone to obtain a representation of the fractured bone in a computing system. The fractured bone defines at least first and second bone fragments separated by a fracture. The method includes imaging a contralateral bone of the patient to obtain a representation of the contralateral bone in the computing system and further includes generating, intraoperatively in the computing system, a virtual model of the fractured bone from data presented in the representation of the fractured bone and a virtual model of the contralateral bone from data presented in the representation of the contralateral bone. The method includes comparing, intraoperatively in the computing system, a spatial dimension measured with respect to the virtual model of the fractured bone with a corresponding spatial dimension measured with respect to the virtual model of the contralateral bone.
