A supporting instrument with a modular intramedullary nail includes a plurality of intramedullary nails and a coupling module. Each intramedullary nail is in a form of a long rod and has a coupling portion arranged between two ends of the intramedullary nail and an abutting surface along a longitudinal face of the intramedullary nail. The coupling module is mounted to the coupling portions of the plurality of intramedullary nails for the abutting surfaces of the plurality of intramedullary nails to abut against each other and for assembling the plurality of intramedullary nails.

A method for treating a surface of a metal implant includes a polishing step, a grafting step and a surface modifying step. The polishing step includes polishing a surface of a metal implant to remove an uneven, natural oxide layer on the surface of the metal implant and to generate an even oxide layer on the surface of the metal implant. The grafting step includes grafting an anti-adhesion macromolecule on an outer face of the even oxide layer. A covalent bond between the anti-adhesion macromolecule and oxygen atoms on the outer face of the even oxide layer is formed. Thus, a macromolecular anti-adhesion layer on the outer face of the even oxide layer can be created. The surface modifying step includes changing a property of the surface of the metal implant with the macromolecular anti-adhesion layer by high temperature and high pressure, providing the metal implant with high hydrophilicity.
