Support orthopaedic device (1) for a knee joint, comprising a proximal connector (2) and a distal connector (3), articulated among themselves and respectively intended to be associated with a proximal bone (100) and a distal bone (101) of a lower limb connected among themselves by a knee joint. The device comprises a first rod (4a) and a second rod (4b), which are hinged, according to hinging axes normal to a median excursion plane of the orthopaedic device (1), to the proximal connector (2) and to the distal connector (3) so as to form with them an articulated quadrilateral. The articulated quadrilateral is planarly mobile according to a plane parallel to the excursion plane between a configuration corresponding to an extended position of the knee joint and configurations corresponding to bendings of different entity of the knee joint; the relative motion imposed to the proximal and distal connectors (2, 3) by the articulated quadrilateral is consistent with the physiological movement of the knee joint. |

1. id="REI-00001" date="20160726" Supportid="REI-00001" id="REI-00002" date="20160726" A support id="REI-00002" orthopaedic device for a knee joint, comprising
a first anchoring device and a second anchoring device, the first and second anchoring devices being arranged to be integrally associated respectively with a proximal bone and a distal bone of a lower limb, and the proximal bone and the distal bone being connected among themselves by a knee joint,; a proximal connector and a distal connector, the proximal connector and the distal connector being articulated among themselves and respectively intendedoperable to be directly connected to said first and a second anchoring devices,; a first rod and a second rod hinged, according to hinging axes normal to a median excursion plane of the orthopaedic device, to the proximal connector and to the distal connector so as to form with them a four-bar linkage;, said four-bar linkage being planarly mobile according to a plane parallel to the excursion plane between a main configuration corresponding to an extended position of the knee joint and a plurality of secondary configurations corresponding to a different degreedegrees of bending of the knee joint, the relative motion imposed to the proximal and distal connectors by the four-bar linkage being consistent with the physiological movement of the knee joint, wherein said proximal connector presents, in correspondence with one of its distal ends, aincludes a reference aperture defined therein at a distal end and normal to the excursion plane, the reference hole, normal to the excursion plane, intendedaperture being operable to temporarily house a guide thread integral with the proximal bone to allow the accurate positioning of the proximal connector with respect to the bone, wherein the device comprises a first means to lock arranged to allow the locking of the four-bar linkage in the main configuration or in any one of its secondary configurations, and wherein at least one of the first and second rods has acomprises a first transversal threaded aperture defined therein, the first transversal threaded hole withaperture having an axis normal to the excursion plane of the device;, and the first means to lock comprisingcomprises a locking screw, insertable into the first transversal holethreaded aperture and into a slot of a first septum integral with one of the distal or proximal connectors;, said locking screw being clampable against a wall of the first septum to lock the four-bar linkage in a wanted configuration. |
