Abstract:
A synthesis device for orthopaedia and traumatology, comprising a cylinder which is made of a Ni--Ti alloy having shape memory, at least one of two ends of said cylinder being split outwardly openable by heating, assuming a memorized shape and maintaining said memorized shape after cooling, said cylinder having a chosen length such that when inserted in a through hole traversing a fracture line of a fractured region of a bone said at least one of the two ends protrudes by a short extent from an outer cortical region of the bone so that said split outwardly opening by heating produces a compaction and coupling of two fracture segments of said fractured region of the bone, said cylinder having a median region which continues with two end regions which are split and divided into a plurality of sectors, an axial hole being provided for insertion of a heating electric scalpel.
