Claim Text:
1. A supporting instrument with a modular intramedullary nail comprising: a plurality of intramedullary nails, wherein each intramedullary nail is in a form of a long rod having two ends spaced along a longitudinal axis and a plurality of longitudinal faces, wherein each long rod has a cross section of a rectangular shape of a constant size between the two ends thereof, with each long rod having a coupling portion and an abutting surface extending along one of the plurality of longitudinal faces, with the coupling portion arranged between the two ends of the long rod, with a corner of the rectangular shape spaced from the abutting surface being pared off to form a round face, wherein the long rod of each intramedullary nail has a curve portion at one of the two ends bent relative to another portion extending from the curve portion to another one of the two ends of each intramedullary nail, wherein the curve portion of the long rod extends non-parallel to the longitudinal axis, wherein the other portion of the long rod extends parallel to the longitudinal axis, and wherein the curve portions of the plurality of intramedullary nails extend in different directions to firmly abut against an inner surface of a medullary cavity, and at least one screw is inserted in a gap between the curve portions and spaced from the other portions of the plurality of intramedullary nails and in a direction which is non-parallel to the longitudinal axis at both of the two ends of each long rod; and a coupling module 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.
