A modular femoral internal implant system for use in the treatment of femoral disorders resulting from injury, disease or congenital defect includes at least three interconnectable components: 1) an elongated epiphyseal/metaphyseal implant, 2) an intramedullary rod and 3) an angled side plate having an elongated plate portion adapted to be secured to the outer cortical wall and a hollow sleeve adapted to extend into the femur. The epiphyseal/metaphyseal implant can be connected to either the angled side plate or the intramedullary rod. The system may also include an elongated bone plate connectable to the angled side plate, one or more additional epiphyseal/metaphyseal implants of variable length, an additional angled side plate, a distal buttress plate connectable to the elongated bone plate, and a plurality of bone screws of a universal design. Preferably, many or all of the components of the system are made of an inert, resilient titanium-base alloy.

Fracture reduction tool is disclosed for use with a guide wire for reducing a bone fracture. The guide wire is of a uniform diameter and has a beaded end for placement into the medullary canal. The tool includes an elongated hollow shaft which can be passed into the medullary canal of the fractured bone through an entry hole prepared in the bone. The shaft has a bore along its length through which the guide wire can selectively pass. The shaft and/or the guide wire can be manipulated into and within the respective medullary canal portions of the fractured bone by translational and/or rotational movements so as to reduce the fracture. The tool also includes a measurement sleeve which moves over the shaft and provides a determination of the length of a nail to be inserted into the medullary canal of the reduced bone. A handle for the proximal end of the shaft allows for ease in manipulation of the shaft and guide wire. Locking mechanisms to secure the measurement sleeve and guide wire in position relative to the shaft are also provided.
