Abstract
A bone screw configured to be screwed into a bone having: an exterior casing; a head having a head interior surface; a tip configured to be driven into the bone; a shaft extending between the head and the tip, the shaft having exterior threads; a magnet; an interior cavity within the bone screw configured to house the magnet; a cap having: a top end having a recess configured to receive a means for driving the bone screw into the bone; and a bottom end having cap threads; the head being configured to receive the cap by having interior threads on the head interior surface; wherein an association of the cap threads with the interior threads causes the cap to be sealed to the head, and thus causes the magnet to be encased within the bone screw with no portion of the magnet exposed outside of the exterior casing.

A bone screw configured to be screwed into a bone, comprising:
- an exterior casing;
- a head having a head interior surface;
- a tip having a distalmost point configured to be driven into the bone;
- a shaft extending between the head and the tip;
- a magnet having a north pole and a south pole;
- an interior cavity within the bone screw configured to house the magnet;
- a cap having:
- a top end having a recess configured to receive a means for driving the bone screw into the bone;
- and
- a bottom end having a set of cap threads;
- wherein the exterior casing encloses the tip, the shaft, at least a portion of the cap, and at least a portion of the head, and wherein a portion of the exterior casing enclosing the shaft comprises a set of exterior threads;
- the head being configured to receive the cap by having a set of interior threads on the head interior surface;
- and
- wherein an association of the set of cap threads with the set of interior threads causes the cap to be sealed to the head, and thus causes the magnet to be encased within the bone screw with no portion of the magnet exposed outside of the exterior casing.
