摘要

This invention relates to implants (10) formed from donor bone for use in lumbar interbody fusion procedures and instruments for performing such procedures. The implants are formed to include a concave surface (14) formed from a portion of the medullary canal of a long bone. The concaved surface defines a recess (15) in the implant that serves as a depot for osteogenic material. Specific instruments for inserting the implants prepared according to this invention and for preparing the intervertebral space to receive the implants are also provided.
