Fluted sub-trochanteric nail system
First Claim
1. A sub-trochanteric intramedullary rod for fracture fixation of long bones comprising an elongated generally cylindrical rod member having a major distal portion and a minor proximal portion, said proximal portion having a diameter greater than the distal portion, a plurality of longitudinal flutes spaced about the periphery of each of said portions, the flutes on said major portion terminating in sharp cutting points which extend beyond said portion.

Abstract
A sub-trochanteric intramedullary rod for use in fracture fixation in the femur characterized in that it is fluted throughout its length and has a minor portion of a diameter greater than its major portion, thereby being of stepped configuration. The distal ends of the flutes in each of the major and minor portions have sharp points thereon adapted to cut into bone and means are provided beneath the points to receive bone particles and chips cut by the points.
