Abstract:
1. A system for the intramedullary fixation of a fractured bone in a body comprising: a first intramedullary plate having a first geometry and defining a plurality of first plate bores; a second intramedullary plate having a second geometry and defining a plurality of second plate bores, wherein the second intramedullary plate interfaces and is fastened to the first intramedullary plate; a plurality of fasteners configured to fasten the first and second intramedullary plates to the bone; and an alignment fixture held outside of the body that indicates the location of the bores of the first and second intramedullary plates and through which the fasteners are aligned with the bores of the first and second intramedullary plates; wherein the bores of the first and second intramedullary plates and the fasteners include mating threads; and wherein the fasteners include a first fastener component and a second fastener component, wherein the first fastener component has an outer wall having the threads and closing a distal end of the first fastener component and has an inner wall defining a non-round geometry and opening a proximal end of the first fastener component, wherein the second fastener component includes a shaft with a knob on a proximal end of the second fastener component and a cross-section that inserts into and engages with the inner wall of the first fastener component on a distal end of the second fastener component.
