<p>The device according to the invention is composed of an axially perforated cylinder having at least one split end so as to form at least two independent sectors. The material of which the cylinder is made is a Ni-Ti alloy with hot, cold or superelastic shape memory. The cylinder is inserted in a hole that passes through the fracture region and is heated with an electric scalpel, causing the independent sectors of the split end to open out and accordingly compact and couple the two fractured segments.</p> |
