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.

Abstract: Endosseous screw (1) for fixing a plate (102) to a bone site (300), comprising an at least partially threaded shaft (2), insertion means for inserting the screw into a bone site and a distal portion (33) provided for engaging said plate to fasten it to said bone site and comprising a head (3) having facets (30) defining an external peripheral profile provided for engagement with a tubular manipulating wrench, to allow the screw (1) to be extracted from the bone site (300) into which it has been inserted, wherein the facets (30) are curvilinear and the external peripheral profile defined by same facets (30) has a convex barrel-like shape, in order to allow a stable coupling between the tubular manipulating wrench and said profile, which is maintained during the untightening phase of screw from plate, even when said tubular manipulating wrench is oriented in an inclined direction with respect to a longitudinal axis (x) of the endosseous screw (1).

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.

Abstract: An intramedullary nail for a fractured elongated bone, comprising a cannulated rod having proximal and distal ends; an outside tubular sleeve for coaxially hosting and guiding the rod; and at least a pair of shape memory elements hosted in corresponding seats at the distal end of the rod. Each shape memory element can be retractably housed in its seat in a first configuration, allowing insertion of the nail into the bone, and can project from a sleeve opening in another configuration. Pairs of transversal holes are provided in proximal portions of the rod and the sleeve. The distal pair of shape memory elements lie on an offset plane to the plane of the proximal holes and are kept in their corresponding seats by a distal cover fixed to the rod. This improves the stability of the nail in the medullary canal.
