Abstract
Provided are fixation members useful in fixing an implant to a bone. The fixation members include an awl tip so as to enable their secure installation by use of an awling motion, which in turn speeds the installation of the fixation members.
Claims28
A bone implant assembly comprising:
- an implant that includes opposed bone-engaging surfaces and further defines at least one aperture extending therethrough;
- and
- a bone anchor configured to extend through the at least one aperture an into a bone so as to fix the implant to the bone, the bone anchor including:
- a proximal end, a distal end opposite the proximal end, and an intermediate portion extending between the proximal and distal ends,
- wherein the distal end defines a tip configured to cut into the bone, at least a portion of the intermediate portion being unthreaded, and the proximal end of the bone anchor defines an exterior thread configured to engage a complementary thread of implant in the aperture.
2 more elements
A bone anchor, comprising:
- a body comprising a tip, a shaft that extends proximally from the tip, and an externally threaded head extending proximally from the shaft,
- the tip configured to penetrate into a bone, wherein at least a portion of the shaft is unthreaded and extends proximally from the tip;
- and
- an engagement feature configured to engage a complementary feature of a driving instrument that is configured to apply a torsional force to the bone anchor so as to drive the tip into the bone.
