Articulated rod of an orthopaedic device

Articulated rod of an orthopaedic device comprising

• a pair of arms,
• two covering plates,
• a polycentric joint that articulates said pair of arms in mutual rotation, where said rotation comprises a direction of flexing rotation and a direction of extension rotation, two rotation pins engaged in through holes of at least one covering plate of said two covering plates and in through holes of said pair of arms,
• wherein every arm of said pair of arms carries a slot, and in wherein the articulated rod comprises a pair of cams, each cam carrying a through hole engaged by the rotation pin and at least one covering plate carrying two through openings,
• wherein each cam is rotatably engaged in a respective through opening of said two through openings of said at least one covering plate, each cam comprising at least one axial extension adapted to be engaged in a respective slot of the arm, each cam comprising a plurality of coupling teeth and an indication element,
• said articulated rod also comprising at least one locking element comprising a plurality of teeth adapted to be engaged with said plurality of coupling teeth of the pair of cams so as to constrain said rotation in at least one direction of rotation of said two directions of rotation in a preset angular width of the rotation.
