Abstract

An implant having an integrated cutting broach and/or cutting burr. The integrated implant may be inserted without requiring separate steps for drilling and broaching bone. The integrated implant assembly may include an integrated implant, a flexible sheath, a delivery rod, and a delivery pin. The implant may have a core which may have any of a variety of cross-sectional geometries. A method for fusing bone may involve inserting the implant laterally through the ilium, through the sacral-iliac joint, and into the sacrum.

Claims (14)

a core having a hollow structure formed by a multi-sided wall;

a delivery pin hole within the core extending from a proximal end to a distal end of the core, the delivery pin hole configured to securely receive a delivery pin; and

a plurality of cutting edges at a distal end of the multi-sided wall, the plurality of cutting edges configured to cut through bone; wherein the multi-sided wall comprises a plurality of interlocking wall sections, the wall sections configured to be implanted independently and interlocked after insertion into a patient.

7. The implant of claim 6 , wherein the biologic aid is hydroxyapatite.

8. The implant of claim 6 , wherein the biologic aid is bone morphogenetic protein.

9. The implant of claim 8 , wherein the bone morphogenetic protein is incorporated into a controlled release formulation.

10. The implant of claim 1 , wherein the multi-sided wall has a plurality of fenestrations.

11. The implant of claim 1 , wherein the plurality of cutting edges taper to points.
