Abstract
A surgical rotational cutting tool, a surgical kit and a method of preparing a femur to receive a stem of a femoral prosthetic. The tool includes a longitudinal axis and a shaft extending along the longitudinal axis, which has a proximal end and a distal end. The tool also includes a head located at the distal end of the shaft. The head includes a pointed distal tip, a bone contacting outer surface having a portion which curves inwards toward the longitudinal axis as it approaches the tip, and a plurality of flutes. The edges of distal parts of neighboring pairs of the flutes meet to define a plurality of cutting edges which extend proximally from the pointed distal tip. A proximal part of each flute extends proximally across the curved portion.
