Abstract

An end member for use with a bone fusion implant is disclosed. The end member has a first portion, a second portion, and a shoulder connecting the two portions. The second portion is sized to fit within the interior of the bone fusion implant in such a fashion that the shoulder rests on the edge of the implant. The top surface of the first portion has at least one slot to receive a surgical instrument such as an inserter and / or distractor to facilitate implantation of the end member and bone fusion implant. The top surface may also have teeth to provide initial mechanical stability between the bone and end plate and promote bone fusion.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation application of U.S. patent application Ser. No. 09 / 497,123 filed Feb. 3, 2000, from which priority of Provisional Application no. 60 / 118,806 filed on Feb. 4, 1999 is claimed under 35 U.S.C. § 119(e), both of which are incorporated by reference herein in their entirety.FIELD OF THE INVENTION

[0002] The present invention relates to a device for bone fusion, and in particular to an end member for a bone fusion implant. BACKGROUND OF THE INVENTION

[0003] The treatment and management of bone defects remains one of the most challenging aspects of orthopaedics. Bone defects occur in a wide variety of clinical situations. Restoring natural anatomical length and shape of any long bone with a bone defect is problematic. Additionally, whenever a vertebra has to be removed, it is necessary to insert a vertebral spacer to restore the natural length and curvature of the spine as well as to promote bone fusion. Resto...
