Abstract
A bone screw and method of inserting a bone screw into a bone is disclosed. In one example, the bone screw includes a tip segment for creating a starter hole in the bone. A pilot segment is located proximally of the tip segment for creating a pilot hole in the bone after creation of the starter hole. A threaded segment is located proximally of the pilot segment for fixedly securing the bone screw in the bone. A head is located proximally of the threaded segment for allowing a surgical rod to be fixedly secured to the bone screw.
Claims45
A bone screw, comprising:
- a pilot segment for creating a pilot hole in said bone after creation of said starter hole;
- a threaded segment proximate said pilot segment for fixedly securing said bone screw in said bone;
- and
- a fixation segment proximate said threaded segment.
A bone screw, comprising:
- a drill bit segment located at a distal end of said bone screw;
- a threaded segment proximate said drill bit segment;
- and
- a fixation point proximate said threaded segment.
A bone screw, comprising:
- a probe segment located at a distal end of said bone screw;
- a threaded segment proximate said probe segment;
- and
- a head proximate said threaded segment.
A method of inserting a bone screw in a bone, comprising:
- forming a pilot hole with a pilot segment of said bone screw proximate said tip segment;
- and
- forming a threaded connection in said bone with a threaded segment of said bone screw proximate said pilot segment such that said bone screw is fixedly secured in said bone.
A method of inserting a bone screw in a bone, comprising:
- (a) forming a starter hole in said bone with a tip segment of said bone screw;
- (b) forming a pilot hole with a drill bit segment of said bone screw;
- (c) forming a threaded connection in said bone with a threaded segment of said bone screw proximate said drill bit segment such that said bone screw is fixedly secured in said bone;
- and
- wherein steps (a), (b), and (c) above are performed by said bone screw in one fluid surgical step.
A method of inserting a bone screw in a bone, comprising the steps of:
- forming a pilot hole with a probe segment of said bone screw;
- and
- forming a threaded connection in said bone with a threaded segment of said bone screw proximate said probe segment such that said bone screw is fixedly secured in said bone.
