Universal implant-to-bone fixation system

An implant-to-bone anchor, comprising:

• a shaft terminated at one end by a head including a shoulder having one or more walls parallel to a longitudinal axis of said shaft and disposed between a shaft-facing surface of said head and said shaft;
• and
• a plurality of generally planar fins each comprising a major radius, a minor radius, a first surface, a second surface and a free edge corresponding to the major radius of each respective generally planar fin and having a beveled cross-section including a leading cutting-edge portion and a trailing cutting-edge portion;
• wherein each of said plurality of generally planar fins are attached to said shaft along less than one half of a circumference of said shaft and angled about the minor radius thereof along an imaginary helix spiraling axially about said shaft such that each 360 degree rotation of the imaginary helix comprises only one of the plurality of generally planar fins,
• wherein each of said plurality of generally planar fins are placed only partially above or partially under an adjacent generally planar fin,
• and
• wherein said minor radius of a generally planar fin of said plurality of generally planar fins which is located closest to said head is the largest in size and wherein said minor radius of a generally planar fin of said plurality of generally planar fins which is located farthest from said head is the smallest in size.
