An interbody spinal implant / fusion cage and implant inserter system for facilitating interbody fusion in the lumbar spine using bone graft while reducing the number of passes made through the patient's disc space and the sensitive surrounding tissue by integrating bone graft delivery into the inserter system. The system combines insertion of the interbody implant with bone graft delivery directly into the disc space. The system includes the interbody implant, an interbody cover plate, an implant inserter assembly, a cover plate inserter, a bone graft plunger and a bone graft funnel. The inserter assembly includes a large rectangular cannula which attaches to a large rectangular posterior opening in the interbody implant instead of a round cannula. The rectangular cannula approximates the shape of the annulotomy and provides a larger cross-sectional area for passage of a much larger quantity of bone graft material without jamming. Related methods and kits are also disclosed.
