1. A method for providing stabilization and compression of a bone fracture, the method comprising:

  • providing an intramedullary prosthesis sized for insertion into the intramedullary canal of a bone, the intramedullary prosthesis consisting of a metallic mesh structure having a round cannulated mesh body terminating in a distal end and a proximal end, and at least two barbs projecting from the round cannulated mesh body;

    positioning the intramedullary prosthesis within the intramedullary canal of the bone so that the round cannulated mesh body spans the bone fracture, with at least one of the at least two barbs being disposed on one side of the bone fracture and at least one of the at least two barbs being disposed on the other side of the bone fracture; and

    radially expanding and longitudinally contracting the round cannulated mesh body so that the at least two barbs grip the side wall of the intramedullary canal on either side of the bone fracture and pull the bone segments on either side of the bone fracture together, whereby to provide stabilization and compression of the bone fracture.
