Nail plate and implantation jig therefor

A system of an orthopedic implant and an implantation jig for facilitating implantation of the implant to a fractured bone, comprising:

• a) the implant including an intramedullary nail portion having a substantially straight endosteal surface and a plurality of screw holes longitudinally displaced along the nail portion, and a plate-like head portion including a first end generally opposite said nail portion and a second ends closer to said nail portion, said first end including at least one catch;
• and
• b) an implantation jig including
• i) a base having at least one anchor which is structured to engage the catch,
• ii) coupling means for coupling the base to the second end of the plate portion of the implant,
• iii) a pedestal extending upward from one end of the base,
• iv) a handle mount provided at an upper portion of the pedestal, and
• v) a handle coupled to the handle mount in a manner which permits the handle to be secured in a first position generally opposite the nail portion and reconfigured into a second position at least partially overlying the nail portion.

A method of implanting a nail-plate implant into a fractured bone having a metaphysis including an articular surface, the implant having a nail portion with screw holes, a plate portion with locking holes, and a neck portion therebetween, comprising:

• a) removing a portion of bone on one side of the fracture;
• b) reducing the fracture;
• c) inserting the nail portion of the nail-plate implant intrafocally into the medullary canal until the necks seats within the space defined one the one side of the fracture and the head portion rests on the metaphysis;
• d) inserting bone support elements into the metaphysis and locking the bone support elements relative to the plate portion;
• e) coupling a jig to the implant, the jig including a handle with guide holes;
• f) positioning the handle of the jig to overlie the nail portion;
• g) drilling holes through the guide holes into the bone and the screw holes in the nail portion;
• and
• h) inserting screws with a driver through a screw guide cannula and into the drilled holes and the screw holes in the nail portion, the screw guide cannula retaining a screw within the cannula if prematurely released from the driver within the cannula.

• and
• h) inserting screws into the drilled holes and the screw holes in the nail portion.
