Abstract
A tool for inserting an intramedullary guide wire comprises a curved metal guide tube having a through lumen and a sharp point at its distal end, a handle for manipulating the tube, and a sighting guide affixed to the tube. The curvature of the guide tube enables the surgeon to align a drilling tool passed through the lumen with the axis of the femoral canal. The sighting guide has a straight distal portion parallel to a line tangent to the lumen axis at the distal end, so that the surgeon can better judge the position and orientation of the tip of the tool within the patient.
