Open axle surgical implant

A method of engaging a surgical tool having spaced apart jaws with inward facing tubular protrusions with a stabilization member connectable bone interfacing implant, said method comprising:

• providing said implant with a body configured for interfacing with a bone structure and a head connected with said body, said head having spaced apart posts juxtaposed by a stabilization member receiving area, each said post having an outward side face, said outward side face having an upper generally vertical surface intersecting with a generally inward directed under surface intersecting with a lower generally vertical surface, said outward side face of each said post having at least one generally cylindrical indention intersecting said upper generally vertical surface and said inward directed under surface, said lower generally vertical surfaces of said posts being spaced apart a distance D1 and said upper generally vertical surfaces being spaced apart a distance D2 greater than said distance D1;
• providing each said generally cylindrical indentions with a circular profile that projects onto and extends along said upper generally vertical surfaces over a 180° arc and defining an indentation window at said under surface having a window width D4, and providing said tubular protrusions with a radius closely approximating a radius of said generally cylindrical indentions, said tubular protrusions having a flattened region defining a protrusion width greater than said window width D4, said tubular protrusions defining a protrusion height perpendicular to said protrusion width that is less than said window width D4;
• separating said tubular protrusions apart to define a separation distance therebetween closely approximating said distance D1;
• positioning said tubular protrusions adjacent said generally lower vertical surfaces defined by said posts of said implant head;
• displacing said tubular protrusions in an upward direction along said generally lower vertical surface toward said generally cylindrical indentions while maintaining said separation distance therebetween;
• and
• angling said surgical tool to generally align said protrusion height with said window width D4 and inserting said tubular protrusions through said indention windows to position said tubular protrusions within said generally cylindrical indentations, and straightening out said surgical tool to lock said tubular protrusions within said generally cylindrical indentions.
