Abstract
A self filling autograft bone screw for stabilizing and fusing bones within a body of a patient. The self filling autograft bone screw includes an elongated body member, a lumen disposed within the elongated body member, a plurality of external threads, a cutting section, and at least one opening disposed along the length of the elongated body member. A system and method for inserting a bone screw into a bone of a patient's body includes advancing and positioning a self-filling bone screw including an elongated body member, a lumen disposed within the elongated body member, a plurality of external threads, a cutting section, and at least one opening disposed along the length of the elongated body member into a bone within a patient's body.
Claims21
A self-filling autograft bone screw, comprising:
- an elongated body member having a proximal portion and a distal portion;
- a lumen disposed within the elongated body member, the lumen extending from a proximal end of the elongated body member to a distal end of the elongated body member;
- a plurality of external threads extending from the proximal portion of the elongated body member to the distal portion of the elongated body member, the plurality of external threads adapted for anchoring the elongated body member within an internal portion of a bone within a patient's body;
- a cutting section disposed at the distal end of the elongated body member, the cutting section adapted to enable penetration of the bone screw into the internal portion of the bone and facilitate the insertion of fragments into the lumen resulting from the penetration of the bone screw into the internal portion of the bone;
- and
- at least one opening disposed along the length of the elongated body member, the at least one opening adapted for facilitating the re-growth of the fragments within the internal portion of the bone and anchoring of the elongated body member within the internal portion of the bone.
A screw system for inserting a bone screw into a bone of a patient's body, comprising:
- an external fastening member used to facilitate insertion of the self filling bone screw into the bone within the patient's body, the external fastening member including at least one flute member disposed along the length of the external fastening member;
- the self filling bone screw having an elongated body member having a proximal portion and a distal portion;
- a lumen disposed within the elongated body member, the lumen extending from a proximal end of the elongated body member to a distal end of the elongated body member;
- a plurality of external threads extending from the proximal portion to the distal portion, the plurality of external threads adapted for anchoring the elongated body member within an internal portion of a bone within a patient's body;
- a cutting section disposed at the distal end of the elongated body member, the cutting section adapted to enable penetration of the bone screw into the internal portion of the bone and facilitate the insertion of fragments into the lumen resulting from the penetration of the bone screw into the internal portion of the bone;
- and
- at least one opening disposed along the length of the elongated body member, the at least one opening adapted for facilitating the re-growth of the fragments within the internal portion of the bone and anchoring of the elongated body member within the internal portion of the bone.
A method for inserting a bone screw into a bone of a patient's body, comprising:
- providing a self-filling bone screw having an elongated body member having a proximal portion and a distal portion;
- a lumen disposed within the elongated body member, the lumen extending from a proximal end of the elongated body member to a distal end of the elongated body member;
- a plurality of external threads extending from the proximal portion to the distal portion, the plurality of external threads adapted for anchoring the elongated body member within an internal portion of a bone within a patient's body;
- a cutting section disposed at the distal end of the elongated body member, the cutting section adapted to enable penetration of the bone screw into the internal portion of the bone and facilitate the insertion of fragments into the lumen resulting from the penetration of the bone screw into the internal portion of the bone;
- at least one opening disposed along the length of the elongated body member, the at least one opening adapted for facilitating the re-growth of the fragments within the internal portion of the bone and anchoring of the elongated body member within the internal portion of the bone;
- forming a hole within the bone;
- advancing the bone screw into the hole within the bone;
- and
- positioning the bone screw into the hole within the bone.
