  • Patent number: 8915914
    Abstract: A method for treating a fracture of a bone with a medullary canal. A first and a second group of three elongated monocortical pins are provided. Each pin has a stem with a first end portion having a conical shape with an external thread for insertion into a cortical portion of a bone. Each pin of the first and second group of three monocortical pins is inserted a predetermined distance from the bone fracture, and penetrates only into the cortical portion of the bone without reaching the medullary cavity, the pins of the first and second group being inserted such that they are not coplanar to each other. The stems of the pins of the first and groups are blocked to a first and a second common clamp element respectively. The first and second clamp elements are joined to a common rod to form a rigid external fixation system.

  • Patent number: 8728079
    Abstract: A clamp applicable to both temporary and definitive orthopaedic external fixation systems comprising a first coupling element having a pair of opposite jaws defining one or more seats to house a first component of the orthopaedic external fixation system. A second coupling element comprises a pair of opposite jaws defining one or more seats to house a second component of the orthopaedic external fixation system. An interconnection pin passes through and connects the first and second coupling elements along an axis of rotation. A fastening means is arranged to bring the clamp from a slack configuration. The first and second coupling elements are relatively rotatable along the axis of rotation to a locked configuration, and are relatively rotatable with each other. These fastening means include manually operable temporary fastening means to temporarily lock the clamp, and definitive fastening means operable with a fastening tool, to definitively lock the clamp.
